While you are authoring your `.gitlab-ci.yml` file, you can validate it by using the [CI Lint](../lint.md) tool. project namespace. For example, `https://gitlab.example.com/gitlab-org/project-123/-/ci/lint`. ## Job keywords A job is defined as a list of keywords that define the job's behavior. The following table lists available keywords for jobs: | Keyword | Description | |:---------------------------------------------------|:------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [`script`](#script) | Shell script that is executed by a runner. | | [`after_script`](#after_script) | Override a set of commands that are executed after job. | | [`allow_failure`](#allow_failure) | Allow job to fail. Failed job does not contribute to commit status. | | [`artifacts`](#artifacts) | List of files and directories to attach to a job on success. Also available: `artifacts:paths`, `artifacts:exclude`, `artifacts:expose_as`, `artifacts:name`, `artifacts:untracked`, `artifacts:when`, `artifacts:expire_in`, and `artifacts:reports`. | | [`before_script`](#before_script) | Override a set of commands that are executed before job. | | [`cache`](#cache) | List of files that should be cached between subsequent runs. Also available: `cache:paths`, `cache:key`, `cache:untracked`, `cache:when`, and `cache:policy`. | | [`coverage`](#coverage) | Code coverage settings for a given job. | | [`dependencies`](#dependencies) | Restrict which artifacts are passed to a specific job by providing a list of jobs to fetch artifacts from. | | [`environment`](#environment) | Name of an environment to which the job deploys. Also available: `environment:name`, `environment:url`, `environment:on_stop`, `environment:auto_stop_in`, and `environment:action`. | | [`except`](#onlyexcept-basic) | Limit when jobs are not created. Also available: [`except:refs`, `except:kubernetes`, `except:variables`, and `except:changes`](#onlyexcept-advanced). | | [`extends`](#extends) | Configuration entries that this job inherits from. | | [`image`](#image) | Use Docker images. Also available: `image:name` and `image:entrypoint`. | | [`include`](#include) | Allows this job to include external YAML files. Also available: `include:local`, `include:file`, `include:template`, and `include:remote`. | | [`interruptible`](#interruptible) | Defines if a job can be canceled when made redundant by a newer run. | | [`only`](#onlyexcept-basic) | Limit when jobs are created. Also available: [`only:refs`, `only:kubernetes`, `only:variables`, and `only:changes`](#onlyexcept-advanced). | | [`pages`](#pages) | Upload the result of a job to use with GitLab Pages. | | [`parallel`](#parallel) | How many instances of a job should be run in parallel. | | [`release`](#release) | Instructs the runner to generate a [Release](../../user/project/releases/index.md) object. | | [`resource_group`](#resource_group) | Limit job concurrency. | | [`retry`](#retry) | When and how many times a job can be auto-retried in case of a failure. | | [`rules`](#rules) | List of conditions to evaluate and determine selected attributes of a job, and whether or not it's created. May not be used alongside `only`/`except`. | | [`services`](#services) | Use Docker services images. Also available: `services:name`, `services:alias`, `services:entrypoint`, and `services:command`. | | [`stage`](#stage) | Defines a job stage (default: `test`). | | [`tags`](#tags) | List of tags that are used to select a runner. | | [`timeout`](#timeout) | Define a custom job-level timeout that takes precedence over the project-wide setting. | | [`trigger`](#trigger) | Defines a downstream pipeline trigger. | | [`variables`](#variables) | Define job variables on a job level. | | [`when`](#when) | When to run job. Also available: `when:manual` and `when:delayed`. | ### Unavailable names for jobs Each job must have a unique name, but there are a few **reserved `keywords` that can't be used as job names**: - `image` - `services` - `stages` - `types` - `before_script` - `after_script` - `variables` - `cache` - `include` ## Global keywords Some keywords must be defined at a global level, affecting all jobs in the pipeline. ### Using reserved keywords If you get validation error when using specific values (for example, `true` or `false`), try to: - Quote them. - Change them to a different form. For example, `/bin/true`. ### Global defaults Some keywords can be set globally as the default for all jobs using the `default:` keyword. Default keywords can then be overridden by job-specific configuration. The following job keywords can be defined inside a `default:` block: - [`image`](#image) - [`services`](#services) - [`before_script`](#before_script) - [`after_script`](#after_script) - [`tags`](#tags) - [`cache`](#cache) - [`artifacts`](#artifacts) - [`retry`](#retry) - [`timeout`](#timeout) - [`interruptible`](#interruptible) In the following example, the `ruby:2.5` image is set as the default for all jobs except the `rspec 2.6` job, which uses the `ruby:2.6` image: ```yaml default: image: ruby:2.5 rspec: script: bundle exec rspec rspec 2.6: image: ruby:2.6 script: bundle exec rspec ``` #### `inherit` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/207484) in GitLab 12.9. You can disable inheritance of globally defined defaults and variables with the `inherit:` keyword. To enable or disable the inheritance of all `variables:` or `default:` keywords, use the following format: - `default: true` or `default: false` - `variables: true` or `variables: false` To inherit only a subset of `default:` keywords or `variables:`, specify what you wish to inherit. Anything not listed is **not** inherited. Use one of the following formats: ```yaml inherit: default: [keyword1, keyword2] variables: [VARIABLE1, VARIABLE2] ``` Or: ```yaml inherit: default: - keyword1 - keyword2 variables: - VARIABLE1 - VARIABLE2 ``` In the example below: - `rubocop`: - inherits: Nothing. - `rspec`: - inherits: the default `image` and the `WEBHOOK_URL` variable. - does **not** inherit: the default `before_script` and the `DOMAIN` variable. - `capybara`: - inherits: the default `before_script` and `image`. - does **not** inherit: the `DOMAIN` and `WEBHOOK_URL` variables. - `karma`: - inherits: the default `image` and `before_script`, and the `DOMAIN` variable. - does **not** inherit: `WEBHOOK_URL` variable. ```yaml default: image: 'ruby:2.4' before_script: - echo Hello World variables: DOMAIN: example.com WEBHOOK_URL: https://my-webhook.example.com rubocop: inherit: default: false variables: false script: bundle exec rubocop rspec: inherit: default: [image] variables: [WEBHOOK_URL] script: bundle exec rspec capybara: inherit: variables: false script: bundle exec capybara karma: inherit: default: true variables: [DOMAIN] script: karma ``` ### `stages` `stages` is used to define stages that contain jobs and is defined globally for the pipeline. The specification of `stages` allows for having flexible multi stage pipelines. The ordering of elements in `stages` defines the ordering of jobs' execution: 1. Jobs of the same stage are run in parallel. 1. Jobs of the next stage are run after the jobs from the previous stage complete successfully. Let's consider the following example, which defines 3 stages: ```yaml stages: - build - test - deploy ``` 1. First, all jobs of `build` are executed in parallel. 1. If all jobs of `build` succeed, the `test` jobs are executed in parallel. 1. If all jobs of `test` succeed, the `deploy` jobs are executed in parallel. 1. If all jobs of `deploy` succeed, the commit is marked as `passed`. 1. If any of the previous jobs fails, the commit is marked as `failed` and no jobs of further stage are executed. There are also two edge cases worth mentioning: 1. If no `stages` are defined in `.gitlab-ci.yml`, then the `build`, `test` and `deploy` are allowed to be used as job's stage by default. 1. If a job does not specify a `stage`, the job is assigned the `test` stage. ### `workflow:rules` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/29654) in GitLab 12.5 The top-level `workflow:` keyword determines whether or not a pipeline is created. It accepts a single `rules:` keyword that is similar to [`rules:` defined within jobs](#rules). Use it to define what can trigger a new pipeline. You can use the [`workflow:rules` templates](#workflowrules-templates) to import a preconfigured `workflow: rules` entry. `workflow: rules` accepts these keywords: - [`if`](#rulesif): Check this rule to determine when to run a pipeline. - [`when`](#when): Specify what to do when the `if` rule evaluates to true. - To run a pipeline, set to `always`. - To prevent pipelines from running, set to `never`. When no rules evaluate to true, the pipeline does not run. Some example `if` clauses for `workflow: rules`: | Example rules | Details | |------------------------------------------------------|-----------------------------------------------------------| | `if: '$CI_PIPELINE_SOURCE == "merge_request_event"'` | Control when merge request pipelines run. | | `if: '$CI_PIPELINE_SOURCE == "push"'` | Control when both branch pipelines and tag pipelines run. | | `if: $CI_COMMIT_TAG` | Control when tag pipelines run. | | `if: $CI_COMMIT_BRANCH` | Control when branch pipelines run. | See the [common `if` clauses for `rules`](#common-if-clauses-for-rules) for more examples. For example, in the following configuration, pipelines run for all `push` events (changes to branches and new tags). Pipelines for push events with `-wip` in the commit message don't run, because they are set to `when: never`. Pipelines for schedules or merge requests don't run either, because no rules evaluate to true for them: ```yaml workflow: rules: - if: $CI_COMMIT_MESSAGE =~ /-wip$/ when: never - if: '$CI_PIPELINE_SOURCE == "push"' ``` This example has strict rules, and pipelines do **not** run in any other case. Alternatively, all of the rules can be `when: never`, with a final `when: always` rule. Pipelines that match the `when: never` rules do not run. All other pipeline types run: ```yaml workflow: rules: - if: '$CI_PIPELINE_SOURCE == "schedule"' when: never - if: '$CI_PIPELINE_SOURCE == "push"' when: never - when: always ``` This example prevents pipelines for schedules or `push` (branches and tags) pipelines. The final `when: always` rule lets all other pipeline types run, **including** merge request pipelines. Be careful not to have rules that match both branch pipelines and merge request pipelines. Similar to `rules` defined in jobs, this can cause [duplicate pipelines](#prevent-duplicate-pipelines). #### `workflow:rules` templates > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/217732) in GitLab 13.0. We provide templates that set up `workflow: rules` for common scenarios. These templates help prevent duplicate pipelines. The [`Branch-Pipelines` template](https://gitlab.com/gitlab-org/gitlab/-/tree/master/lib/gitlab/ci/templates/Workflows/Branch-Pipelines.gitlab-ci.yml) makes your pipelines run for branches and tags. Branch pipeline status is displayed within merge requests that use the branch as a source. However, this pipeline type does not support any features offered by [Merge Request Pipelines](../merge_request_pipelines/), like [Pipelines for Merge Results](../merge_request_pipelines/#pipelines-for-merged-results) or [Merge Trains](../merge_request_pipelines/pipelines_for_merged_results/merge_trains/). Use this template if you are intentionally avoiding those features. It is [included](#include) as follows: ```yaml include: - template: 'Workflows/Branch-Pipelines.gitlab-ci.yml' ``` The [`MergeRequest-Pipelines` template](https://gitlab.com/gitlab-org/gitlab/-/tree/master/lib/gitlab/ci/templates/Workflows/MergeRequest-Pipelines.gitlab-ci.yml) makes your pipelines run for the default branch (usually `master`), tags, and all types of merge request pipelines. Use this template if you use any of the the [Pipelines for Merge Requests features](../merge_request_pipelines/), as mentioned above. It is [included](#include) as follows: ```yaml include: - template: 'Workflows/MergeRequest-Pipelines.gitlab-ci.yml' ``` ### `include` > - Introduced in [GitLab Premium](https://about.gitlab.com/pricing/) 10.5. > - Available for Starter, Premium, and Ultimate in GitLab 10.6 and later. > - [Moved](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/42861) to GitLab Core in 11.4. Using the `include` keyword allows the inclusion of external YAML files. This helps to break down the CI/CD configuration into multiple files and increases readability for long configuration files. It's also possible to have template files stored in a central repository and projects include their configuration files. This helps avoid duplicated configuration, for example, global default variables for all projects. `include` requires the external YAML file to have the extensions `.yml` or `.yaml`, otherwise the external file is not included. Using [YAML anchors](#anchors) across different YAML files sourced by `include` is not supported. You must only refer to anchors in the same file. Instead of using YAML anchors, you can use the [`extends` keyword](#extends). `include` supports the following inclusion methods: | Keyword | Method | |:--------------------------------|:------------------------------------------------------------------| | [`local`](#includelocal) | Include a file from the local project repository. | | [`file`](#includefile) | Include a file from a different project repository. | | [`remote`](#includeremote) | Include a file from a remote URL. Must be publicly accessible. | | [`template`](#includetemplate) | Include templates that are provided by GitLab. | The `include` methods do not support [variable expansion](../variables/where_variables_can_be_used.md#variables-usage). `.gitlab-ci.yml` configuration included by all methods is evaluated at pipeline creation. The configuration is a snapshot in time and persisted in the database. Any changes to referenced `.gitlab-ci.yml` configuration is not reflected in GitLab until the next pipeline is created. The files defined by `include` are: - Deep merged with those in `.gitlab-ci.yml`. - Always evaluated first and merged with the content of `.gitlab-ci.yml`, regardless of the position of the `include` keyword. TIP: **Tip:** Use merging to customize and override included CI/CD configurations with local definitions. Local definitions in `.gitlab-ci.yml` override included definitions. #### `include:local` `include:local` includes a file from the same repository as `.gitlab-ci.yml`. It's referenced using full paths relative to the root directory (`/`). You can only use files that are tracked by Git on the same branch your configuration file is on. In other words, when using a `include:local`, make sure that both `.gitlab-ci.yml` and the local file are on the same branch. Including local files through Git submodules paths is not supported. All [nested includes](#nested-includes) are executed in the scope of the same project, so it's possible to use local, project, remote, or template includes. Example: ```yaml include: - local: '/templates/.gitlab-ci-template.yml' ``` Local includes can be used as a replacement for symbolic links that are not followed. This can be defined as a short local include: ```yaml include: '.gitlab-ci-production.yml' ``` #### `include:file` > [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/53903) in GitLab 11.7. To include files from another private project under the same GitLab instance, use `include:file`. This file is referenced using full paths relative to the root directory (`/`). For example: ```yaml include: - project: 'my-group/my-project' file: '/templates/.gitlab-ci-template.yml' ``` You can also specify a `ref`. If not specified, it defaults to the `HEAD` of the project: ```yaml include: - project: 'my-group/my-project' ref: master file: '/templates/.gitlab-ci-template.yml' - project: 'my-group/my-project' ref: v1.0.0 file: '/templates/.gitlab-ci-template.yml' - project: 'my-group/my-project' ref: 787123b47f14b552955ca2786bc9542ae66fee5b # Git SHA file: '/templates/.gitlab-ci-template.yml' ``` All [nested includes](#nested-includes) are executed in the scope of the target project. This means you can use local (relative to target project), project, remote, or template includes. ##### Multiple files from a project > - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/26793) in GitLab 13.6. > - It's [deployed behind a feature flag](../../user/feature_flags.md), enabled by default. > - It's enabled on GitLab.com. > - It's recommended for production use. > - For GitLab self-managed instances, GitLab administrators can opt to disable it. **(CORE ONLY)** You can include multiple files from the same project: ```yaml include: - project: 'my-group/my-project' ref: master file: - '/templates/.builds.yml' - '/templates/.tests.yml' ``` Including multiple files from the same project is under development but ready for production use. It is deployed behind a feature flag that is **enabled by default**. [GitLab administrators with access to the GitLab Rails console](../../administration/feature_flags.md) can opt to disable it. To enable it: ```ruby Feature.enable(:ci_include_multiple_files_from_project) ``` To disable it: ```ruby Feature.disable(:ci_include_multiple_files_from_project) ``` #### `include:remote` `include:remote` can be used to include a file from a different location, using HTTP/HTTPS, referenced by the full URL. The remote file must be publicly accessible by a GET request, because authentication schemas in the remote URL are not supported. For example: ```yaml include: - remote: 'https://gitlab.com/awesome-project/raw/master/.gitlab-ci-template.yml' ``` All [nested includes](#nested-includes) are executed without context as public user, so only another remote or public project, or template, is allowed. #### `include:template` > [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/53445) in GitLab 11.7. `include:template` can be used to include `.gitlab-ci.yml` templates that are [shipped with GitLab](https://gitlab.com/gitlab-org/gitlab/tree/master/lib/gitlab/ci/templates). For example: ```yaml # File sourced from GitLab's template collection include: - template: Auto-DevOps.gitlab-ci.yml ``` Multiple `include:template` files: ```yaml include: - template: Android-Fastlane.gitlab-ci.yml - template: Auto-DevOps.gitlab-ci.yml ``` All [nested includes](#nested-includes) are executed only with the permission of the user, so it's possible to use project, remote or template includes. #### Nested includes > [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/56836) in GitLab 11.9. Nested includes allow you to compose a set of includes. A total of 100 includes is allowed, but duplicate includes are considered a configuration error. In [GitLab 12.4](https://gitlab.com/gitlab-org/gitlab/-/issues/28212) and later, the time limit to resolve all files is 30 seconds. #### Additional `includes` examples There is a list of [additional `includes` examples](includes.md) available. ## Keyword details The following are detailed explanations for keywords used to configure CI/CD pipelines. ### `image` Used to specify [a Docker image](../docker/using_docker_images.md#what-is-an-image) to use for the job. For: - Usage examples, see [Define `image` and `services` from `.gitlab-ci.yml`](../docker/using_docker_images.md#define-image-and-services-from-gitlab-ciyml). - Detailed usage information, refer to [Docker integration](../docker/README.md) documentation. #### `image:name` An [extended Docker configuration option](../docker/using_docker_images.md#extended-docker-configuration-options). For more information, see [Available settings for `image`](../docker/using_docker_images.md#available-settings-for-image). #### `image:entrypoint` An [extended Docker configuration option](../docker/using_docker_images.md#extended-docker-configuration-options). For more information, see [Available settings for `image`](../docker/using_docker_images.md#available-settings-for-image). #### `services` Used to specify a [service Docker image](../docker/using_docker_images.md#what-is-a-service), linked to a base image specified in [`image`](#image). For: - Usage examples, see [Define `image` and `services` from `.gitlab-ci.yml`](../docker/using_docker_images.md#define-image-and-services-from-gitlab-ciyml). - Detailed usage information, refer to [Docker integration](../docker/README.md) documentation. - For example services, see [GitLab CI/CD Services](../services/README.md). ##### `services:name` An [extended Docker configuration option](../docker/using_docker_images.md#extended-docker-configuration-options). For more information, see [Available settings for `services`](../docker/using_docker_images.md#available-settings-for-services). ##### `services:alias` An [extended Docker configuration option](../docker/using_docker_images.md#extended-docker-configuration-options). For more information, see [Available settings for `services`](../docker/using_docker_images.md#available-settings-for-services). ##### `services:entrypoint` An [extended Docker configuration option](../docker/using_docker_images.md#extended-docker-configuration-options). For more information, see [Available settings for `services`](../docker/using_docker_images.md#available-settings-for-services). ##### `services:command` An [extended Docker configuration option](../docker/using_docker_images.md#extended-docker-configuration-options). For more information, see [Available settings for `services`](../docker/using_docker_images.md#available-settings-for-services). ### `script` `script` is the only required keyword that a job needs. It's a shell script that is executed by the runner. For example: ```yaml job: script: "bundle exec rspec" ``` You can use [YAML anchors with `script`](#yaml-anchors-for-scripts). This keyword can also contain several commands in an array: ```yaml job: script: - uname -a - bundle exec rspec ``` Sometimes, `script` commands must be wrapped in single or double quotes. For example, commands that contain a colon (`:`) must be wrapped in quotes. The YAML parser needs to interpret the text as a string rather than a "key: value" pair. Be careful when using special characters: `:`, `{`, `}`, `[`, `]`, `,`, `&`, `*`, `#`, `?`, `|`, `-`, `<`, `>`, `=`, `!`, `%`, `@`, `` ` ``. If any of the script commands return an exit code other than zero, the job fails and further commands are not executed. Store the exit code in a variable to avoid this behavior: ```yaml job: script: - false || exit_code=$? - if [ $exit_code -ne 0 ]; then echo "Previous command failed"; fi; ``` #### `before_script` > Introduced in GitLab 8.7 and requires GitLab Runner v1.2. `before_script` is used to define commands that should run before each job, including deploy jobs, but after the restoration of any [artifacts](#artifacts). This must be an array. Scripts specified in `before_script` are concatenated with any scripts specified in the main [`script`](#script), and executed together in a single shell. It's possible to overwrite a globally defined `before_script` if you define it in a job: ```yaml default: before_script: - echo "Execute this in all jobs that don't already have a before_script section." job1: script: - echo "This executes after the global before_script." job: before_script: - echo "Execute this instead of the global before_script." script: - echo "This executes after the job's `before_script`" ``` You can use [YAML anchors with `before_script`](#yaml-anchors-for-scripts). #### `after_script` Introduced in GitLab 8.7 and requires GitLab Runner v1.2. `after_script` is used to define commands that run after each job, including failed jobs. This must be an array. If a job times out or is cancelled, the `after_script` commands are not executed. Support for executing `after_script` commands for timed-out or cancelled jobs [is planned](https://gitlab.com/gitlab-org/gitlab/-/issues/15603). Scripts specified in `after_script` are executed in a new shell, separate from any `before_script` or `script` scripts. As a result, they: - Have a current working directory set back to the default. - Have no access to changes done by scripts defined in `before_script` or `script`, including: - Command aliases and variables exported in `script` scripts. - Changes outside of the working tree (depending on the runner executor), like software installed by a `before_script` or `script` script. - Have a separate timeout, which is hard coded to 5 minutes. See the [related issue](https://gitlab.com/gitlab-org/gitlab-runner/-/issues/2716) for details. - Don't affect the job's exit code. If the `script` section succeeds and the `after_script` times out or fails, the job exits with code `0` (`Job Succeeded`). ```yaml default: after_script: - echo "Execute this in all jobs that don't already have an after_script section." job1: script: - echo "This executes first. When it completes, the global after_script executes." job: script: - echo "This executes first. When it completes, the job's `after_script` executes." after_script: - echo "Execute this instead of the global after_script." ``` You can use [YAML anchors with `after_script`](#yaml-anchors-for-scripts). #### Script syntax You can use special syntax in [`script`](README.md#script) sections to: - [Split long commands](script.md#split-long-commands) into multiline commands. - [Use color codes](script.md#add-color-codes-to-script-output) to make job logs easier to review. - [Create custom collapsible sections](../jobs/index.md#custom-collapsible-sections) to simplify job log output. ### `stage` `stage` is defined per-job and relies on [`stages`](#stages), which is defined globally. It allows to group jobs into different stages, and jobs of the same `stage` are executed in parallel (subject to [certain conditions](#using-your-own-runners)). For example: ```yaml stages: - build - test - deploy job 0: stage: .pre script: make something useful before build stage job 1: stage: build script: make build dependencies job 2: stage: build script: make build artifacts job 3: stage: test script: make test job 4: stage: deploy script: make deploy job 5: stage: .post script: make something useful at the end of pipeline ``` #### Using your own runners When you use your own runners, GitLab Runner runs only one job at a time by default. See the `concurrent` flag in [runner global settings](https://docs.gitlab.com/runner/configuration/advanced-configuration.html#the-global-section) for more information. Jobs run on your own runners in parallel only if: - Run on different runners. - The runner's `concurrent` setting has been changed. #### `.pre` and `.post` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/31441) in GitLab 12.4. The following stages are available to every pipeline: - `.pre`, which is guaranteed to always be the first stage in a pipeline. - `.post`, which is guaranteed to always be the last stage in a pipeline. User-defined stages are executed after `.pre` and before `.post`. A pipeline is not created if all jobs are in `.pre` or `.post` stages. The order of `.pre` and `.post` can't be changed, even if defined out of order in `.gitlab-ci.yml`. For example, the following are equivalent configuration: - Configured in order: ```yaml stages: - .pre - a - b - .post ``` - Configured out of order: ```yaml stages: - a - .pre - b - .post ``` - Not explicitly configured: ```yaml stages: - a - b ``` ### `extends` > Introduced in GitLab 11.3. `extends` defines entry names that a job that uses `extends` inherits from. It's an alternative to using [YAML anchors](#anchors) and is a little more flexible and readable: ```yaml .tests: script: rake test stage: test only: refs: - branches rspec: extends: .tests script: rake rspec only: variables: - $RSPEC ``` In the example above, the `rspec` job inherits from the `.tests` template job. GitLab performs a reverse deep merge based on the keys. GitLab: - Merges the `rspec` contents into `.tests` recursively. - Doesn't merge the values of the keys. The result is this `rspec` job, where `script: rake test` is overwritten by `script: rake rspec`: ```yaml rspec: script: rake rspec stage: test only: refs: - branches variables: - $RSPEC ``` If you do want to include the `rake test`, see [`before_script`](#before_script) or [`after_script`](#after_script). `.tests` in this example is a [hidden job](#hide-jobs), but it's possible to inherit from regular jobs as well. `extends` supports multi-level inheritance. You should avoid using more than 3 levels, but you can use as many as eleven. The following example has two levels of inheritance: ```yaml .tests: only: - pushes .rspec: extends: .tests script: rake rspec rspec 1: variables: RSPEC_SUITE: '1' extends: .rspec rspec 2: variables: RSPEC_SUITE: '2' extends: .rspec spinach: extends: .tests script: rake spinach ``` In GitLab 12.0 and later, it's also possible to use multiple parents for `extends`. #### Merge details `extends` is able to merge hashes but not arrays. The algorithm used for merge is "closest scope wins", so keys from the last member always override anything defined on other levels. For example: ```yaml .only-important: variables: URL: "http://my-url.internal" IMPORTANT_VAR: "the details" only: - master - stable tags: - production script: - echo "Hello world!" .in-docker: variables: URL: "http://docker-url.internal" tags: - docker image: alpine rspec: variables: GITLAB: "is-awesome" extends: - .only-important - .in-docker script: - rake rspec ``` This results in the following `rspec` job: ```yaml rspec: variables: URL: "http://docker-url.internal" IMPORTANT_VAR: "the details" GITLAB: "is-awesome" only: - master - stable tags: - docker image: alpine script: - rake rspec ``` Note that in the example above: - `variables` sections have been merged but that `URL: "http://my-url.internal"` has been overwritten by `URL: "http://docker-url.internal"`. - `tags: ['production']` has been overwritten by `tags: ['docker']`. - `script` has not been merged but rather `script: ['echo "Hello world!"']` has been overwritten by `script: ['rake rspec']`. Arrays can be merged using [YAML anchors](#anchors). #### Using `extends` and `include` together `extends` works across configuration files combined with `include`. For example, if you have a local `included.yml` file: ```yaml .template: script: - echo Hello! ``` Then, in `.gitlab-ci.yml` you can use it like this: ```yaml include: included.yml useTemplate: image: alpine extends: .template ``` This example runs a job called `useTemplate` that runs `echo Hello!` as defined in the `.template` job, and uses the `alpine` Docker image as defined in the local job. ### `rules` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/27863) in GitLab 12.3. The `rules` keyword can be used to include or exclude jobs in pipelines. Rules are evaluated *in order* until the first match. When matched, the job is either included or excluded from the pipeline, depending on the configuration. If included, the job also has [certain attributes](#rules-attributes) added to it. `rules` replaces [`only/except`](#onlyexcept-basic) and can't be used in conjunction with it. If you attempt to use both keywords in the same job, the linter returns a `key may not be used with rules` error. #### Rules attributes The job attributes allowed by `rules` are: - [`when`](#when): If not defined, defaults to `when: on_success`. - If used as `when: delayed`, `start_in` is also required. - [`allow_failure`](#allow_failure): If not defined, defaults to `allow_failure: false`. If a rule evaluates to true, and `when` has any value except `never`, the job is included in the pipeline. For example: ```yaml docker build: script: docker build -t my-image:$CI_COMMIT_REF_SLUG . rules: - if: '$CI_COMMIT_BRANCH == "master"' when: delayed start_in: '3 hours' allow_failure: true ``` Additional job configuration may be added to rules in the future. If something useful is not available, please [open an issue](https://gitlab.com/gitlab-org/gitlab/-/issues). #### Rules clauses Available rule clauses are: | Clause | Description | |----------------------------|------------------------------------------------------------------------------------------------------------------------------------| | [`if`](#rulesif) | Add or exclude jobs from a pipeline by evaluating an `if` statement. Similar to [`only:variables`](#onlyvariablesexceptvariables). | | [`changes`](#ruleschanges) | Add or exclude jobs from a pipeline based on what files are changed. Same as [`only:changes`](#onlychangesexceptchanges). | | [`exists`](#rulesexists) | Add or exclude jobs from a pipeline based on the presence of specific files. | Rules are evaluated in order until a match is found. If a match is found, the attributes are checked to see if the job should be added to the pipeline. If no attributes are defined, the defaults are: - `when: on_success` - `allow_failure: false` The job is added to the pipeline: - If a rule matches and has `when: on_success`, `when: delayed` or `when: always`. - If no rules match, but the last clause is `when: on_success`, `when: delayed` or `when: always` (with no rule). The job is not added to the pipeline: - If no rules match, and there is no standalone `when: on_success`, `when: delayed` or `when: always`. - If a rule matches, and has `when: never` as the attribute. For example, using `if` clauses to strictly limit when jobs run: ```yaml job: script: "echo Hello, Rules!" rules: - if: '$CI_PIPELINE_SOURCE == "merge_request_event"' when: manual allow_failure: true - if: '$CI_PIPELINE_SOURCE == "schedule"' ``` In this example: - If the pipeline is for a merge request, the first rule matches, and the job is added to the [merge request pipeline](../merge_request_pipelines/index.md) with attributes of: - `when: manual` (manual job) - `allow_failure: true` (allows the pipeline to continue running even if the manual job is not run) - If the pipeline is **not** for a merge request, the first rule doesn't match, and the second rule is evaluated. - If the pipeline is a scheduled pipeline, the second rule matches, and the job is added to the scheduled pipeline. Since no attributes were defined, it is added with: - `when: on_success` (default) - `allow_failure: false` (default) - In **all other cases**, no rules match, so the job is **not** added to any other pipeline. Alternatively, you can define a set of rules to exclude jobs in a few cases, but run them in all other cases: ```yaml job: script: "echo Hello, Rules!" rules: - if: '$CI_PIPELINE_SOURCE == "merge_request_event"' when: never - if: '$CI_PIPELINE_SOURCE == "schedule"' when: never - when: on_success ``` - If the pipeline is for a merge request, the job is **not** be added to the pipeline. - If the pipeline is a scheduled pipeline, the job is **not** be added to the pipeline. - In **all other cases**, the job is added to the pipeline, with `when: on_success`. CAUTION: **Caution:** If you use a `when:` clause as the final rule (not including `when: never`), two simultaneous pipelines may start. Both push pipelines and merge request pipelines can be triggered by the same event (a push to the source branch for an open merge request). See how to [prevent duplicate pipelines](#prevent-duplicate-pipelines) for more details. #### Prevent duplicate pipelines Jobs defined with `rules` can trigger multiple pipelines with the same action. You don't have to explicitly configure rules for each type of pipeline to trigger them accidentally. Rules that are too loose (allowing too many types of pipelines) could cause a second pipeline to run unexpectedly. Some configurations that have the potential to cause duplicate pipelines cause a [pipeline warning](../troubleshooting.md#pipeline-warnings) to be displayed. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/219431) in GitLab 13.3. For example: ```yaml job: script: "echo This creates double pipelines!" rules: - if: '$CUSTOM_VARIABLE == "false"' when: never - when: always ``` This job does not run when `$CUSTOM_VARIABLE` is false, but it *does* run in **all** other pipelines, including **both** push (branch) and merge request pipelines. With this configuration, every push to an open merge request's source branch causes duplicated pipelines. There are multiple ways to avoid this: - Use [`workflow: rules`](#workflowrules) to specify which types of pipelines can run. To eliminate duplicate pipelines, allow only merge request pipelines or push (branch) pipelines. - Rewrite the rules to run the job only in very specific cases, and avoid using a final `when:` rule: ```yaml job: script: "echo This does NOT create double pipelines!" rules: - if: '$CUSTOM_VARIABLE == "true" && $CI_PIPELINE_SOURCE == "merge_request_event"' ``` You can prevent duplicate pipelines by changing the job rules to avoid either push (branch) pipelines or merge request pipelines. However, if you use a `- when: always` rule without `workflow: rules`, GitLab still displays a [pipeline warning](../troubleshooting.md#pipeline-warnings). For example, the following does not trigger double pipelines, but is not recommended without `workflow: rules`: ```yaml job: script: "echo This does NOT create double pipelines!" rules: - if: '$CI_PIPELINE_SOURCE == "push"' when: never - when: always ``` Do not include both push and merge request pipelines in the same job: ```yaml job: script: "echo This creates double pipelines!" rules: - if: '$CI_PIPELINE_SOURCE == "push"' - if: '$CI_PIPELINE_SOURCE == "merge_request_event"' ``` Also, do not mix `only/except` jobs with `rules` jobs in the same pipeline. It may not cause YAML errors, but the different default behaviors of `only/except` and `rules` can cause issues that are difficult to troubleshoot: ```yaml job-with-no-rules: script: "echo This job runs in branch pipelines." job-with-rules: script: "echo This job runs in merge request pipelines." rules: - if: '$CI_PIPELINE_SOURCE == "merge_request_event"' ``` For every change pushed to the branch, duplicate pipelines run. One branch pipeline runs a single job (`job-with-no-rules`), and one merge request pipeline runs the other job (`job-with-rules`). Jobs with no rules default to [`except: merge_requests`](#onlyexcept-basic), so `job-with-no-rules` runs in all cases except merge requests. It is not possible to define rules based on whether or not a branch has an open merge request associated with it. You can't configure a job to be included in: - Only branch pipelines when the branch doesn't have a merge request associated with it. - Only merge request pipelines when the branch has a merge request associated with it. See the [related issue](https://gitlab.com/gitlab-org/gitlab/-/issues/201845) for more details. #### `rules:if` `rules:if` clauses determine whether or not jobs are added to a pipeline by evaluating a simple `if` statement. If the `if` statement is true, the job is either included or excluded from a pipeline. In plain English, `if` rules can be interpreted as one of: - "If this rule evaluates to true, add the job" (default). - "If this rule evaluates to true, do not add the job" (by adding `when: never`). `rules:if` differs slightly from `only:variables` by accepting only a single expression string per rule, rather than an array of them. Any set of expressions to be evaluated can be [conjoined into a single expression](../variables/README.md#conjunction--disjunction) by using `&&` or `||`, and use the [variable matching syntax](../variables/README.md#syntax-of-environment-variable-expressions). Unlike variables in [`script`](../variables/README.md#syntax-of-environment-variables-in-job-scripts) sections, variables in rules expressions are always formatted as `$VARIABLE`. `if:` clauses are evaluated based on the values of [predefined environment variables](../variables/predefined_variables.md) or [custom environment variables](../variables/README.md#custom-environment-variables). For example: ```yaml job: script: "echo Hello, Rules!" rules: - if: '$CI_MERGE_REQUEST_SOURCE_BRANCH_NAME =~ /^feature/ && $CI_MERGE_REQUEST_TARGET_BRANCH_NAME == "master"' when: always - if: '$CI_MERGE_REQUEST_SOURCE_BRANCH_NAME =~ /^feature/' when: manual allow_failure: true - if: '$CI_MERGE_REQUEST_SOURCE_BRANCH_NAME' # Checking for the presence of a variable is possible ``` Some details regarding the logic that determines the `when` for the job: - If none of the provided rules match, the job is set to `when: never` and is not included in the pipeline. - A rule without any conditional clause, such as a `when` or `allow_failure` rule without `if` or `changes`, always matches, and is always used if reached. - If a rule matches and has no `when` defined, the rule uses the `when` defined for the job, which defaults to `on_success` if not defined. - You can define `when` once per rule, or once at the job-level, which applies to all rules. You can't mix `when` at the job-level with `when` in rules. ##### Common `if` clauses for `rules` For behavior similar to the [`only`/`except` keywords](#onlyexcept-basic), you can check the value of the `$CI_PIPELINE_SOURCE` variable: | Value | Description | |-------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `api` | For pipelines triggered by the [pipelines API](../../api/pipelines.md#create-a-new-pipeline). | | `chat` | For pipelines created by using a [GitLab ChatOps](../chatops/README.md) command. | | `external` | When using CI services other than GitLab. | | `external_pull_request_event` | When an external pull request on GitHub is created or updated. See [Pipelines for external pull requests](../ci_cd_for_external_repos/index.md#pipelines-for-external-pull-requests). | | `merge_request_event` | For pipelines created when a merge request is created or updated. Required to enable [merge request pipelines](../merge_request_pipelines/index.md), [merged results pipelines](../merge_request_pipelines/pipelines_for_merged_results/index.md), and [merge trains](../merge_request_pipelines/pipelines_for_merged_results/merge_trains/index.md). | | `parent_pipeline` | For pipelines triggered by a [parent/child pipeline](../parent_child_pipelines.md) with `rules`, use this in the child pipeline configuration so that it can be triggered by the parent pipeline. | | `pipeline` | For [multi-project pipelines](../multi_project_pipelines.md) created by [using the API with `CI_JOB_TOKEN`](../multi_project_pipelines.md#triggering-multi-project-pipelines-through-api), or the [`trigger`](#trigger) keyword. | | `push` | For pipelines triggered by a `git push` event, including for branches and tags. | | `schedule` | For [scheduled pipelines](../pipelines/schedules.md). | | `trigger` | For pipelines created by using a [trigger token](../triggers/README.md#trigger-token). | | `web` | For pipelines created by using **Run pipeline** button in the GitLab UI, from the project's **CI/CD > Pipelines** section. | | `webide` | For pipelines created by using the [WebIDE](../../user/project/web_ide/index.md). | For example: ```yaml job: script: "echo Hello, Rules!" rules: - if: '$CI_PIPELINE_SOURCE == "schedule"' when: manual allow_failure: true - if: '$CI_PIPELINE_SOURCE == "push"' ``` This example runs the job as a manual job in scheduled pipelines or in push pipelines (to branches or tags), with `when: on_success` (default). It does not add the job to any other pipeline type. Another example: ```yaml job: script: "echo Hello, Rules!" rules: - if: '$CI_PIPELINE_SOURCE == "merge_request_event"' - if: '$CI_PIPELINE_SOURCE == "schedule"' ``` This example runs the job as a `when: on_success` job in [merge request pipelines](../merge_request_pipelines/index.md) and scheduled pipelines. It does not run in any other pipeline type. Other commonly used variables for `if` clauses: - `if: $CI_COMMIT_TAG`: If changes are pushed for a tag. - `if: $CI_COMMIT_BRANCH`: If changes are pushed to any branch. - `if: '$CI_COMMIT_BRANCH == "master"'`: If changes are pushed to `master`. - `if: '$CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH'`: If changes are pushed to the default branch (usually `master`). Useful if reusing the same configuration in multiple projects with potentially different default branches. - `if: '$CI_COMMIT_BRANCH =~ /regex-expression/'`: If the commit branch matches a regular expression. - `if: '$CUSTOM_VARIABLE !~ /regex-expression/'`: If the [custom variable](../variables/README.md#custom-environment-variables) `CUSTOM_VARIABLE` does **not** match a regular expression. - `if: '$CUSTOM_VARIABLE == "value1"'`: If the custom variable `CUSTOM_VARIABLE` is exactly `value1`. #### `rules:changes` `rules:changes` determines whether or not to add jobs to a pipeline by checking for changes to specific files. `rules: changes` works exactly the same way as [`only: changes` and `except: changes`](#onlychangesexceptchanges), accepting an array of paths. It's recommended to only use `rules: changes` with branch pipelines or merge request pipelines. For example, it's common to use `rules: changes` with merge request pipelines: ```yaml docker build: script: docker build -t my-image:$CI_COMMIT_REF_SLUG . rules: - if: '$CI_PIPELINE_SOURCE == "merge_request_event"' changes: - Dockerfile when: manual allow_failure: true ``` In this example: - If the pipeline is a merge request pipeline, check `Dockerfile` for changes. - If `Dockerfile` has changed, add the job to the pipeline as a manual job, and allow the pipeline to continue running even if the job is not triggered (`allow_failure: true`). - If `Dockerfile` has not changed, do not add job to any pipeline (same as `when: never`). To use `rules: changes` with branch pipelines instead of merge request pipelines, change the `if:` clause in the example above to: ```yaml rules: - if: $CI_PIPELINE_SOURCE == "push" && $CI_COMMIT_BRANCH ``` To implement a rule similar to [`except:changes`](#onlychangesexceptchanges), use `when: never`. CAUTION: **Caution:** You can use `rules: changes` with other pipeline types, but it is not recommended because `rules: changes` always evaluates to true when there is no Git `push` event. Tag pipelines, scheduled pipelines, and so on do **not** have a Git `push` event associated with them. A `rules: changes` job is **always** added to those pipeline if there is no `if:` statement that limits the job to branch or merge request pipelines. ##### Variables in `rules:changes` > - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/34272) in GitLab 13.6. > - It was [deployed behind a feature flag](../../user/feature_flags.md), disabled by default. > - [Became enabled by default](https://gitlab.com/gitlab-org/gitlab/-/issues/267192) in GitLab 13.6. > - It's enabled on GitLab.com. > - It's recommended for production use. > - For GitLab self-managed instances, GitLab administrators can opt to [disable it](#enable-or-disable-variables-support-in-ruleschanges). **(CORE ONLY)** CAUTION: **Warning:** This feature might not be available to you. Check the **version history** note above for details. Environment variables can be used in `rules:changes` expressions to determine when to add jobs to a pipeline: ```yaml docker build: variables: DOCKERFILES_DIR: 'path/to/files/' script: docker build -t my-image:$CI_COMMIT_REF_SLUG . rules: - changes: - $DOCKERFILES_DIR/* ``` The `$` character can be used for both variables and paths. For example, if the `$DOCKERFILES_DIR` variable exists, its value is used. If it does not exist, the `$` is interpreted as being part of a path. ###### Enable or disable variables support in `rules:changes` **(CORE ONLY)** Variables support in `rules:changes` is under development, but is ready for production use. It is deployed behind a feature flag that is **enabled by default**. [GitLab administrators with access to the GitLab Rails console](../../administration/feature_flags.md) can opt to disable it. To enable it: ```ruby Feature.enable(:ci_variable_expansion_in_rules_changes) ``` To disable it: ```ruby Feature.disable(:ci_variable_expansion_in_rules_changes) ``` #### `rules:exists` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/24021) in GitLab 12.4. `exists` accepts an array of paths and matches if any of these paths exist as files in the repository. For example: ```yaml job: script: docker build -t my-image:$CI_COMMIT_REF_SLUG . rules: - exists: - Dockerfile ``` You can also use glob patterns to match multiple files in any directory within the repository. For example: ```yaml job: script: bundle exec rspec rules: - exists: - spec/**.rb ``` For performance reasons, using `exists` with patterns is limited to 10,000 checks. After the 10,000th check, rules with patterned globs always match. #### `rules:allow_failure` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/30235) in GitLab 12.8. You can use [`allow_failure: true`](#allow_failure) within `rules:` to allow a job to fail, or a manual job to wait for action, without stopping the pipeline itself. All jobs using `rules:` default to `allow_failure: false` if `allow_failure:` is not defined. The rule-level `rules:allow_failure` option overrides the job-level [`allow_failure`](#allow_failure) option, and is only applied when the job is triggered by the particular rule. ```yaml job: script: "echo Hello, Rules!" rules: - if: '$CI_MERGE_REQUEST_TARGET_BRANCH_NAME == "master"' when: manual allow_failure: true ``` In this example, if the first rule matches, then the job has `when: manual` and `allow_failure: true`. #### Complex rule clauses To conjoin `if`, `changes`, and `exists` clauses with an `AND`, use them in the same rule. In the following example: - If the `Dockerfile` file or any file in `/docker/scripts` has changed, and var=blah, then the job runs manually - Otherwise, the job isn't included in the pipeline. ```yaml docker build: script: docker build -t my-image:$CI_COMMIT_REF_SLUG . rules: - if: '$VAR == "string value"' changes: # Include the job and set to when:manual if any of the follow paths match a modified file. - Dockerfile - docker/scripts/* when: manual # - when: never would be redundant here, this is implied any time rules are listed. ``` Keywords such as `branches` or `refs` that are available for `only`/`except` are not available in `rules`. They are being individually considered for their usage and behavior in this context. Future keyword improvements are being discussed in our [epic for improving `rules`](https://gitlab.com/groups/gitlab-org/-/epics/2783), where anyone can add suggestions or requests. You can use [parentheses](../variables/README.md#parentheses) with `&&` and `||` to build more complicated variable expressions. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/230938) in GitLab 13.3: ```yaml job1: script: - echo This rule uses parentheses. rules: if: ($CI_COMMIT_BRANCH == "master" || $CI_COMMIT_BRANCH == "develop") && $MY_VARIABLE ``` CAUTION: **Caution:** [Before GitLab 13.3](https://gitlab.com/gitlab-org/gitlab/-/issues/230938), rules that use both `||` and `&&` may evaluate with an unexpected order of operations. ### `only`/`except` (basic) NOTE: **Note:** The [`rules`](#rules) syntax is an improved, more powerful solution for defining when jobs should run or not. Consider using `rules` instead of `only/except` to get the most out of your pipelines. `only` and `except` are two keywords that set a job policy to limit when jobs are created: 1. `only` defines the names of branches and tags the job runs for. 1. `except` defines the names of branches and tags the job does **not** run for. There are a few rules that apply to the usage of job policy: - `only` and `except` are inclusive. If both `only` and `except` are defined in a job specification, the ref is filtered by `only` and `except`. - `only` and `except` allow the use of regular expressions ([supported regexp syntax](#supported-onlyexcept-regexp-syntax)). - `only` and `except` allow to specify a repository path to filter jobs for forks. In addition, `only` and `except` allow the use of special keywords: | **Value** | **Description** | |--------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `api` | For pipelines triggered by the [pipelines API](../../api/pipelines.md#create-a-new-pipeline). | | `branches` | When the Git reference for a pipeline is a branch. | | `chat` | For pipelines created by using a [GitLab ChatOps](../chatops/README.md) command. | | `external` | When using CI services other than GitLab. | | `external_pull_requests` | When an external pull request on GitHub is created or updated (See [Pipelines for external pull requests](../ci_cd_for_external_repos/index.md#pipelines-for-external-pull-requests)). | | `merge_requests` | For pipelines created when a merge request is created or updated. Enables [merge request pipelines](../merge_request_pipelines/index.md), [merged results pipelines](../merge_request_pipelines/pipelines_for_merged_results/index.md), and [merge trains](../merge_request_pipelines/pipelines_for_merged_results/merge_trains/index.md). | | `pipelines` | For [multi-project pipelines](../multi_project_pipelines.md) created by [using the API with `CI_JOB_TOKEN`](../multi_project_pipelines.md#triggering-multi-project-pipelines-through-api), or the [`trigger`](#trigger) keyword. | | `pushes` | For pipelines triggered by a `git push` event, including for branches and tags. | | `schedules` | For [scheduled pipelines](../pipelines/schedules.md). | | `tags` | When the Git reference for a pipeline is a tag. | | `triggers` | For pipelines created by using a [trigger token](../triggers/README.md#trigger-token). | | `web` | For pipelines created by using **Run pipeline** button in the GitLab UI, from the project's **CI/CD > Pipelines** section. | In the example below, `job` runs only for refs that start with `issue-`, whereas all branches are skipped: ```yaml job: # use regexp only: - /^issue-.*$/ # use special keyword except: - branches ``` Pattern matching is case-sensitive by default. Use `i` flag modifier, like `/pattern/i` to make a pattern case-insensitive: ```yaml job: # use regexp only: - /^issue-.*$/i # use special keyword except: - branches ``` In this example, `job` runs only for refs that are tagged, or if a build is explicitly requested by an API trigger or a [Pipeline Schedule](../pipelines/schedules.md): ```yaml job: # use special keywords only: - tags - triggers - schedules ``` The repository path can be used to have jobs executed only for the parent repository and not forks: ```yaml job: only: - branches@gitlab-org/gitlab except: - master@gitlab-org/gitlab - /^release/.*$/@gitlab-org/gitlab ``` The above example runs `job` for all branches on `gitlab-org/gitlab`, except `master` and those with names prefixed with `release/`. If a job does not have an `only` rule, `only: ['branches', 'tags']` is set by default. If it does not have an `except` rule, it's empty. For example, ```yaml job: script: echo 'test' ``` is translated to: ```yaml job: script: echo 'test' only: ['branches', 'tags'] ``` #### Regular expressions The `@` symbol denotes the beginning of a ref's repository path. To match a ref name that contains the `@` character in a regular expression, you must use the hex character code match `\x40`. Only the tag or branch name can be matched by a regular expression. The repository path, if given, is always matched literally. To match the tag or branch name, the entire ref name part of the pattern must be a regular expression surrounded by `/`. For example, you can't use `issue-/.*/` to match all tag names or branch names that begin with `issue-`, but you can use `/issue-.*/`. Regular expression flags must be appended after the closing `/`. TIP: **Tip:** Use anchors `^` and `$` to avoid the regular expression matching only a substring of the tag name or branch name. For example, `/^issue-.*$/` is equivalent to `/^issue-/`, while just `/issue/` would also match a branch called `severe-issues`. #### Supported `only`/`except` regexp syntax In GitLab 11.9.4, GitLab began internally converting the regexp used in `only` and `except` keywords to [RE2](https://github.com/google/re2/wiki/Syntax). [RE2](https://github.com/google/re2/wiki/Syntax) limits the set of available features due to computational complexity, and some features, like negative lookaheads, became unavailable. Only a subset of features provided by [Ruby Regexp](https://ruby-doc.org/core/Regexp.html) are now supported. From GitLab 11.9.7 to GitLab 12.0, GitLab provided a feature flag to let you use the unsafe regexp syntax. This flag allowed compatibility with the previous syntax version so you could gracefully migrate to the new syntax. ```ruby Feature.enable(:allow_unsafe_ruby_regexp) ``` ### `only`/`except` (advanced) GitLab supports both simple and complex strategies, so it's possible to use an array and a hash configuration scheme. Four keys are available: - `refs` - `variables` - `changes` - `kubernetes` If you use multiple keys under `only` or `except`, the keys are evaluated as a single conjoined expression. That is: - `only:` includes the job if **all** of the keys have at least one condition that matches. - `except:` excludes the job if **any** of the keys have at least one condition that matches. With `only`, individual keys are logically joined by an `AND`. A job is added to the pipeline if the following is true: - `(any listed refs are true) AND (any listed variables are true) AND (any listed changes are true) AND (any chosen Kubernetes status matches)` In the example below, the `test` job is `only` created when **all** of the following are true: - The pipeline has been [scheduled](../pipelines/schedules.md) **or** runs for `master`. - The `variables` keyword matches. - The `kubernetes` service is active on the project. ```yaml test: script: npm run test only: refs: - master - schedules variables: - $CI_COMMIT_MESSAGE =~ /run-end-to-end-tests/ kubernetes: active ``` With `except`, individual keys are logically joined by an `OR`. A job is **not** added if the following is true: - `(any listed refs are true) OR (any listed variables are true) OR (any listed changes are true) OR (a chosen Kubernetes status matches)` In the example below, the `test` job is **not** created when **any** of the following are true: - The pipeline runs for the `master` branch. - There are changes to the `README.md` file in the root directory of the repository. ```yaml test: script: npm run test except: refs: - master changes: - "README.md" ``` #### `only:refs`/`except:refs` > `refs` policy introduced in GitLab 10.0. The `refs` strategy can take the same values as the [simplified only/except configuration](#onlyexcept-basic). In the example below, the `deploy` job is created only when the pipeline is [scheduled](../pipelines/schedules.md) or runs for the `master` branch: ```yaml deploy: only: refs: - master - schedules ``` #### `only:kubernetes`/`except:kubernetes` > `kubernetes` policy introduced in GitLab 10.0. The `kubernetes` strategy accepts only the `active` keyword. In the example below, the `deploy` job is created only when the Kubernetes service is active in the project: ```yaml deploy: only: kubernetes: active ``` #### `only:variables`/`except:variables` > `variables` policy introduced in GitLab 10.7. The `variables` keyword defines variable expressions. These expressions determine whether or not a job should be created. Examples of using variable expressions: ```yaml deploy: script: cap staging deploy only: refs: - branches variables: - $RELEASE == "staging" - $STAGING ``` Another use case is excluding jobs depending on a commit message: ```yaml end-to-end: script: rake test:end-to-end except: variables: - $CI_COMMIT_MESSAGE =~ /skip-end-to-end-tests/ ``` You can use [parentheses](../variables/README.md#parentheses) with `&&` and `||` to build more complicated variable expressions. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/230938) in GitLab 13.3: ```yaml job1: script: - echo This rule uses parentheses. only: variables: - ($CI_COMMIT_BRANCH == "master" || $CI_COMMIT_BRANCH == "develop") && $MY_VARIABLE ``` #### `only:changes`/`except:changes` > `changes` policy [introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/19232) in GitLab 11.4. Using the `changes` keyword with `only` or `except` makes it possible to define if a job should be created based on files modified by a Git push event. The `only:changes` policy is only useful for pipelines triggered by the following refs: - `branches` - `external_pull_requests` - `merge_requests` (see additional details about [using `only:changes` with pipelines for merge requests](#using-onlychanges-with-pipelines-for-merge-requests)) CAUTION: **Caution:** In pipelines with [sources other than the three above](../variables/predefined_variables.md) `changes` can't determine if a given file is new or old and always returns `true`. This includes pipelines triggered by pushing new tags. Configuring jobs to use `only: changes` with other `only: refs` keywords is possible, but not recommended. A basic example of using `only: changes`: ```yaml docker build: script: docker build -t my-image:$CI_COMMIT_REF_SLUG . only: refs: - branches changes: - Dockerfile - docker/scripts/* - dockerfiles/**/* - more_scripts/*.{rb,py,sh} ``` When you push commits to an existing branch, the `docker build` job is created, but only if changes were made to any of the following: - The `Dockerfile` file. - Any of the files in the `docker/scripts/` directory. - Any of the files and subdirectories in the `dockerfiles` directory. - Any of the files with `rb`, `py`, `sh` extensions in the `more_scripts` directory. CAUTION: **Warning:** If you use `only:changes` with [only allow merge requests to be merged if the pipeline succeeds](../../user/project/merge_requests/merge_when_pipeline_succeeds.md#only-allow-merge-requests-to-be-merged-if-the-pipeline-succeeds), you should [also use `only:merge_requests`](#using-onlychanges-with-pipelines-for-merge-requests). Otherwise it may not work as expected. You can also use glob patterns to match multiple files in either the root directory of the repository, or in _any_ directory within the repository. However, they must be wrapped in double quotes or GitLab can't parse them. For example: ```yaml test: script: npm run test only: refs: - branches changes: - "*.json" - "**/*.sql" ``` You can skip a job if a change is detected in any file with a `.md` extension in the root directory of the repository: ```yaml build: script: npm run build except: changes: - "*.md" ``` If you change multiple files, but only one file ends in `.md`, the `build` job is still skipped. The job does not run for any of the files. Read more about how to use this feature with: - [New branches or tags *without* pipelines for merge requests](#using-onlychanges-without-pipelines-for-merge-requests). - [Scheduled pipelines](#using-onlychanges-with-scheduled-pipelines). ##### Using `only:changes` with pipelines for merge requests With [pipelines for merge requests](../merge_request_pipelines/index.md), it's possible to define a job to be created based on files modified in a merge request. To deduce the correct base SHA of the source branch, we recommend combining this keyword with `only: [merge_requests]`. This way, file differences are correctly calculated from any further commits, thus all changes in the merge requests are properly tested in pipelines. For example: ```yaml docker build service one: script: docker build -t my-service-one-image:$CI_COMMIT_REF_SLUG . only: refs: - merge_requests changes: - Dockerfile - service-one/**/* ``` In this scenario, if a merge request changes files in the `service-one` directory or the `Dockerfile`, GitLab creates the `docker build service one` job. For example: ```yaml docker build service one: script: docker build -t my-service-one-image:$CI_COMMIT_REF_SLUG . only: changes: - Dockerfile - service-one/**/* ``` In the example above, the pipeline might fail because of changes to a file in `service-one/**/*`. A later commit that doesn't have changes in `service-one/**/*` but does have changes to the `Dockerfile` can pass. The job only tests the changes to the `Dockerfile`. GitLab checks the **most recent pipeline** that **passed**. If the merge request is mergeable, it doesn't matter that an earlier pipeline failed because of a change that has not been corrected. When you use this configuration, ensure that the most recent pipeline properly corrects any failures from previous pipelines. ##### Using `only:changes` without pipelines for merge requests Without [pipelines for merge requests](../merge_request_pipelines/index.md), pipelines run on branches or tags that don't have an explicit association with a merge request. In this case, a previous SHA is used to calculate the diff, which is equivalent to `git diff HEAD~`. This can result in some unexpected behavior, including: - When pushing a new branch or a new tag to GitLab, the policy always evaluates to true. - When pushing a new commit, the changed files are calculated using the previous commit as the base SHA. ##### Using `only:changes` with scheduled pipelines `only:changes` always evaluates as "true" in [Scheduled pipelines](../pipelines/schedules.md). All files are considered to have "changed" when a scheduled pipeline runs. ### `needs` > - [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/47063) in GitLab 12.2. > - In GitLab 12.3, maximum number of jobs in `needs` array raised from five to 50. > - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/30631) in GitLab 12.8, `needs: []` lets jobs start immediately. The `needs:` keyword enables executing jobs out-of-order, allowing you to implement a [directed acyclic graph](../directed_acyclic_graph/index.md) in your `.gitlab-ci.yml`. This lets you run some jobs without waiting for other ones, disregarding stage ordering so you can have multiple stages running concurrently. Let's consider the following example: ```yaml linux:build: stage: build mac:build: stage: build lint: stage: test needs: [] linux:rspec: stage: test needs: ["linux:build"] linux:rubocop: stage: test needs: ["linux:build"] mac:rspec: stage: test needs: ["mac:build"] mac:rubocop: stage: test needs: ["mac:build"] production: stage: deploy ``` This example creates four paths of execution: - Linter: the `lint` job runs immediately without waiting for the `build` stage to complete because it has no needs (`needs: []`). - Linux path: the `linux:rspec` and `linux:rubocop` jobs runs as soon as the `linux:build` job finishes without waiting for `mac:build` to finish. - macOS path: the `mac:rspec` and `mac:rubocop` jobs runs as soon as the `mac:build` job finishes, without waiting for `linux:build` to finish. - The `production` job runs as soon as all previous jobs finish; in this case: `linux:build`, `linux:rspec`, `linux:rubocop`, `mac:build`, `mac:rspec`, `mac:rubocop`. #### Requirements and limitations - If `needs:` is set to point to a job that is not instantiated because of `only/except` rules or otherwise does not exist, the pipeline is not created and a YAML error is shown. - The maximum number of jobs that a single job can need in the `needs:` array is limited: - For GitLab.com, the limit is 50. For more information, see our [infrastructure issue](https://gitlab.com/gitlab-com/gl-infra/infrastructure/-/issues/7541). - For self-managed instances, the limit is: 50. This limit [can be changed](#changing-the-needs-job-limit). - If `needs:` refers to a job that is marked as `parallel:`. the current job depends on all parallel jobs being created. - `needs:` is similar to `dependencies:` in that it must use jobs from prior stages, meaning it's impossible to create circular dependencies. Depending on jobs in the current stage is not possible either, but support [is planned](https://gitlab.com/gitlab-org/gitlab/-/issues/30632). - Related to the above, stages must be explicitly defined for all jobs that have the keyword `needs:` or are referred to by one. ##### Changing the `needs:` job limit **(CORE ONLY)** The maximum number of jobs that can be defined within `needs:` defaults to 50. A GitLab administrator with [access to the GitLab Rails console](../../administration/feature_flags.md) can choose a custom limit. For example, to set the limit to 100: ```ruby Plan.default.actual_limits.update!(ci_needs_size_limit: 100) ``` To disable directed acyclic graphs (DAG), set the limit to `0`. #### Artifact downloads with `needs` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/14311) in GitLab v12.6. When using `needs`, artifact downloads are controlled with `artifacts: true` (default) or `artifacts: false`. In GitLab 12.6 and later, you can't combine the [`dependencies`](#dependencies) keyword with `needs` to control artifact downloads in jobs. `dependencies` is still valid in jobs that do not use `needs`. In the example below, the `rspec` job downloads the `build_job` artifacts, while the `rubocop` job doesn't: ```yaml build_job: stage: build artifacts: paths: - binaries/ rspec: stage: test needs: - job: build_job artifacts: true rubocop: stage: test needs: - job: build_job artifacts: false ``` Additionally, in the three syntax examples below, the `rspec` job downloads the artifacts from all three `build_jobs`. `artifacts` is true for `build_job_1` and **defaults** to true for both `build_job_2` and `build_job_3`. ```yaml rspec: needs: - job: build_job_1 artifacts: true - job: build_job_2 - build_job_3 ``` #### Cross project artifact downloads with `needs` **(PREMIUM)** > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/14311) in GitLab v12.7. Use `needs` to download artifacts from up to five jobs in pipelines: - [On other refs in the same project](#artifact-downloads-between-pipelines-in-the-same-project). - In different projects, groups and namespaces. ```yaml build_job: stage: build script: - ls -lhR needs: - project: namespace/group/project-name job: build-1 ref: master artifacts: true ``` `build_job` downloads the artifacts from the latest successful `build-1` job on the `master` branch in the `group/project-name` project. If the project is in the same group or namespace, you can omit them from the `project:` key. For example, `project: group/project-name` or `project: project-name`. The user running the pipeline must have at least `reporter` access to the group or project, or the group/project must have public visibility. ##### Artifact downloads between pipelines in the same project Use `needs` to download artifacts from different pipelines in the current project. Set the `project` keyword as the current project's name, and specify a ref. In this example, `build_job` downloads the artifacts for the latest successful `build-1` job with the `other-ref` ref: ```yaml build_job: stage: build script: - ls -lhR needs: - project: group/same-project-name job: build-1 ref: other-ref artifacts: true ``` Environment variables support for `project:`, `job:`, and `ref` was [introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/202093) in GitLab 13.3. [Feature flag removed](https://gitlab.com/gitlab-org/gitlab/-/issues/235761) in GitLab 13.4. For example: ```yaml build_job: stage: build script: - ls -lhR needs: - project: $CI_PROJECT_PATH job: $DEPENDENCY_JOB_NAME ref: $CI_COMMIT_BRANCH artifacts: true ``` Downloading artifacts from jobs that are run in [`parallel:`](#parallel) is not supported. ### `tags` Use `tags` to select a specific runner from the list of all runners that are available for the project. When you register a runner, you can specify the runner's tags, for example `ruby`, `postgres`, `development`. In this example, the job is run by a runner that has both `ruby` and `postgres` tags defined. ```yaml job: tags: - ruby - postgres ``` You can use tags to run different jobs on different platforms. For example, if you have an OS X runner with tag `osx` and a Windows runner with tag `windows`, you can run a job on each platform: ```yaml windows job: stage: - build tags: - windows script: - echo Hello, %USERNAME%! osx job: stage: - build tags: - osx script: - echo "Hello, $USER!" ``` ### `allow_failure` Use `allow_failure` when you want to let a job fail without impacting the rest of the CI suite. The default value is `false`, except for [manual](#whenmanual) jobs using the `when: manual` syntax, unless using [`rules:`](#rules) syntax, where all jobs default to false, *including* `when: manual` jobs. When `allow_failure` is enabled and the job fails, the job shows an orange warning in the UI. However, the logical flow of the pipeline considers the job a success/passed, and is not blocked. Assuming all other jobs are successful, the job's stage and its pipeline show the same orange warning. However, the associated commit is marked as "passed", without warnings. In the example below, `job1` and `job2` run in parallel, but if `job1` fails, it doesn't stop the next stage from running, because it's marked with `allow_failure: true`: ```yaml job1: stage: test script: - execute_script_that_will_fail allow_failure: true job2: stage: test script: - execute_script_that_will_succeed job3: stage: deploy script: - deploy_to_staging ``` ### `when` `when` is used to implement jobs that are run in case of failure or despite the failure. `when` can be set to one of the following values: 1. `on_success` - execute job only when all jobs from prior stages succeed (or are considered succeeding because they have `allow_failure: true`). This is the default. 1. `on_failure` - execute job only when at least one job from prior stages fails. 1. `always` - execute job regardless of the status of jobs from prior stages. 1. `manual` - execute job manually (added in GitLab 8.10). Read about [manual jobs](#whenmanual) below. 1. `delayed` - execute job after a certain period (added in GitLab 11.14). Read about [delayed jobs](#whendelayed) below. 1. `never`: - With [`rules`](#rules), don't execute job. - With [`workflow:rules`](#workflowrules), don't run pipeline. For example: ```yaml stages: - build - cleanup_build - test - deploy - cleanup build_job: stage: build script: - make build cleanup_build_job: stage: cleanup_build script: - cleanup build when failed when: on_failure test_job: stage: test script: - make test deploy_job: stage: deploy script: - make deploy when: manual cleanup_job: stage: cleanup script: - cleanup after jobs when: always ``` The above script: 1. Executes `cleanup_build_job` only when `build_job` fails. 1. Always executes `cleanup_job` as the last step in pipeline regardless of success or failure. 1. Executes `deploy_job` when you run it manually in the GitLab UI. #### `when:manual` > - Introduced in GitLab 8.10. > - Blocking manual jobs were introduced in GitLab 9.0. > - Protected actions were introduced in GitLab 9.2. A manual job is a type of job that is not executed automatically and must be explicitly started by a user. You might want to use manual jobs for things like deploying to production. To make a job manual, add `when: manual` to its configuration. Manual jobs can be started from the pipeline, job, [environment](../environments/index.md#configuring-manual-deployments), and deployment views. Manual jobs can be either optional or blocking: - **Optional**: Manual jobs have [`allow_failure: true](#allow_failure) set by default and are considered optional. The status of an optional manual job does not contribute to the overall pipeline status. A pipeline can succeed even if all its manual jobs fail. - **Blocking**: To make a blocking manual job, add `allow_failure: false` to its configuration. Blocking manual jobs stop further execution of the pipeline at the stage where the job is defined. To let the pipeline continue running, click **{play}** (play) on the blocking manual job. Merge requests in projects with [merge when pipeline succeeds](../../user/project/merge_requests/merge_when_pipeline_succeeds.md) enabled can't be merged with a blocked pipeline. Blocked pipelines show a status of **blocked**. When you use [`rules:`](#rules), `allow_failure` defaults to `false`, including for manual jobs. To trigger a manual job, a user must have permission to merge to the assigned branch. You can use [protected branches](../../user/project/protected_branches.md) to more strictly [protect manual deployments](#protecting-manual-jobs) from being run by unauthorized users. In [GitLab 13.5](https://gitlab.com/gitlab-org/gitlab/-/issues/201938) and later, you can use `when:manual` in the same job as [`trigger`](#trigger). In GitLab 13.4 and earlier, using them together causes the error `jobs:#{job-name} when should be on_success, on_failure or always`. It is deployed behind the `:ci_manual_bridges` [feature flag](../../user/feature_flags.md), which is **enabled by default**. [GitLab administrators with access to the Rails console](../../administration/feature_flags.md) can opt to disable it. ##### Protecting manual jobs **(PREMIUM)** It's possible to use [protected environments](../environments/protected_environments.md) to define a precise list of users authorized to run a manual job. By allowing only users associated with a protected environment to trigger manual jobs, it's possible to implement some special use cases, such as: - More precisely limiting who can deploy to an environment. - Enabling a pipeline to be blocked until an approved user "approves" it. To do this, you must: 1. Add an `environment` to the job. For example: ```yaml deploy_prod: stage: deploy script: - echo "Deploy to production server" environment: name: production url: https://example.com when: manual only: - master ``` 1. In the [protected environments settings](../environments/protected_environments.md#protecting-environments), select the environment (`production` in the example above) and add the users, roles or groups that are authorized to trigger the manual job to the **Allowed to Deploy** list. Only those in this list can trigger this manual job, as well as GitLab administrators who are always able to use protected environments. Additionally, if you define a manual job as blocking by adding `allow_failure: false`, the pipeline's next stages don't run until the manual job is triggered. You can use this to define a list of users allowed to "approve" later pipeline stages by triggering the blocking manual job. #### `when:delayed` > [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/51352) in GitLab 11.4. Delayed job are for executing scripts after a certain period. This is useful if you want to avoid jobs entering `pending` state immediately. You can set the period with `start_in` key. The value of `start_in` key is an elapsed time in seconds, unless a unit is provided. `start_in` key must be less than or equal to one week. Examples of valid values include: - `'5'` - `5 seconds` - `30 minutes` - `1 day` - `1 week` When there is a delayed job in a stage, the pipeline doesn't progress until the delayed job has finished. This means this keyword can also be used for inserting delays between different stages. The timer of a delayed job starts immediately after the previous stage has completed. Similar to other types of jobs, a delayed job's timer doesn't start unless the previous stage passed. The following example creates a job named `timed rollout 10%` that is executed 30 minutes after the previous stage has completed: ```yaml timed rollout 10%: stage: deploy script: echo 'Rolling out 10% ...' when: delayed start_in: 30 minutes ``` You can stop the active timer of a delayed job by clicking the **{time-out}** (**Unschedule**) button. This job can no longer be scheduled to run automatically. You can, however, execute the job manually. To start a delayed job immediately, click the **Play** button. Soon GitLab Runner picks up and starts the job. ### `environment` > - Introduced in GitLab 8.9. > - You can read more about environments and find more examples in the > [documentation about environments](../environments/index.md). `environment` is used to define that a job deploys to a specific environment. If `environment` is specified and no environment under that name exists, a new one is created automatically. In its simplest form, the `environment` keyword can be defined like: ```yaml deploy to production: stage: deploy script: git push production HEAD:master environment: production ``` In the above example, the `deploy to production` job is marked as doing a deployment to the `production` environment. #### `environment:name` > - Introduced in GitLab 8.11. > - Before GitLab 8.11, the name of an environment could be defined as a string like > `environment: production`. The recommended way now is to define it under the > `name` keyword. > - The `name` keyword can use any of the defined CI variables, > including predefined, secure variables and `.gitlab-ci.yml` [`variables`](#variables). > You however can't use variables defined under `script`. The `environment` name can contain: - letters - digits - spaces - `-` - `_` - `/` - `$` - `{` - `}` Common names are `qa`, `staging`, and `production`, but you can use whatever name works with your workflow. Instead of defining the name of the environment right after the `environment` keyword, it's also possible to define it as a separate value. For that, use the `name` keyword under `environment`: ```yaml deploy to production: stage: deploy script: git push production HEAD:master environment: name: production ``` #### `environment:url` > - Introduced in GitLab 8.11. > - Before GitLab 8.11, the URL could be added only in GitLab's UI. The > recommended way now is to define it in `.gitlab-ci.yml`. > - The `url` keyword can use any of the defined CI variables, > including predefined, secure variables and `.gitlab-ci.yml` [`variables`](#variables). > You however can't use variables defined under `script`. This optional value exposes buttons that take you to the defined URL In this example, if the job finishes successfully, it creates buttons in the merge requests and in the environments/deployments pages that point to `https://prod.example.com`. ```yaml deploy to production: stage: deploy script: git push production HEAD:master environment: name: production url: https://prod.example.com ``` #### `environment:on_stop` > - [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/22191) in GitLab 8.13. > - Starting with GitLab 8.14, when you have an environment that has a stop action > defined, GitLab automatically triggers a stop action when the associated > branch is deleted. Closing (stopping) environments can be achieved with the `on_stop` keyword defined under `environment`. It declares a different job that runs to close the environment. Read the `environment:action` section for an example. #### `environment:action` > [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/22191) in GitLab 8.13. The `action` keyword can be used to specify jobs that prepare, start, or stop environments. | **Value** | **Description** | |-----------|---------------------------------------------------------------------------------------------------------------------------------------------------------------| | start | Default value. Indicates that job starts the environment. The deployment is created after the job starts. | | prepare | Indicates that job is only preparing the environment. Does not affect deployments. [Read more about environments](../environments/index.md#prepare-an-environment) | | stop | Indicates that job stops deployment. See the example below. | Take for instance: ```yaml review_app: stage: deploy script: make deploy-app environment: name: review/$CI_COMMIT_REF_NAME url: https://$CI_ENVIRONMENT_SLUG.example.com on_stop: stop_review_app stop_review_app: stage: deploy variables: GIT_STRATEGY: none script: make delete-app when: manual environment: name: review/$CI_COMMIT_REF_NAME action: stop ``` In the above example, the `review_app` job deploys to the `review` environment. A new `stop_review_app` job is listed under `on_stop`. After the `review_app` job is finished, it triggers the `stop_review_app` job based on what is defined under `when`. In this case, it is set to `manual`, so it needs a [manual action](#whenmanual) from GitLab's user interface to run. Also in the example, `GIT_STRATEGY` is set to `none`. If the `stop_review_app` job is [automatically triggered](../environments/index.md#automatically-stopping-an-environment), the runner won’t try to check out the code after the branch is deleted. The example also overwrites global variables. If your `stop` `environment` job depends on global variables, you can use [anchor variables](#yaml-anchors-for-variables) when you set the `GIT_STRATEGY`. This changes the job without overriding the global variables. The `stop_review_app` job is **required** to have the following keywords defined: - `when` - [reference](#when) - `environment:name` - `environment:action` Additionally, both jobs should have matching [`rules`](../yaml/README.md#onlyexcept-basic) or [`only/except`](../yaml/README.md#onlyexcept-basic) configuration. In the example above, if the configuration is not identical: - The `stop_review_app` job might not be included in all pipelines that include the `review_app` job. - It is not possible to trigger the `action: stop` to stop the environment automatically. #### `environment:auto_stop_in` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/20956) in GitLab 12.8. The `auto_stop_in` keyword is for specifying the lifetime of the environment, that when expired, GitLab automatically stops them. For example, ```yaml review_app: script: deploy-review-app environment: name: review/$CI_COMMIT_REF_NAME auto_stop_in: 1 day ``` When the environment for `review_app` is created, the environment's lifetime is set to `1 day`. Every time the review app is deployed, that lifetime is also reset to `1 day`. For more information, see [the environments auto-stop documentation](../environments/index.md#environments-auto-stop) #### `environment:kubernetes` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/27630) in GitLab 12.6. The `kubernetes` block is used to configure deployments to a [Kubernetes cluster](../../user/project/clusters/index.md) that is associated with your project. For example: ```yaml deploy: stage: deploy script: make deploy-app environment: name: production kubernetes: namespace: production ``` This configuration sets up the `deploy` job to deploy to the `production` environment, using the `production` [Kubernetes namespace](https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/). For more information, see [Available settings for `kubernetes`](../environments/index.md#configuring-kubernetes-deployments). NOTE: **Note:** Kubernetes configuration is not supported for Kubernetes clusters that are [managed by GitLab](../../user/project/clusters/index.md#gitlab-managed-clusters). To follow progress on support for GitLab-managed clusters, see the [relevant issue](https://gitlab.com/gitlab-org/gitlab/-/issues/38054). #### Dynamic environments > - [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/21971) in GitLab 8.12 and GitLab Runner 1.6. > - The `$CI_ENVIRONMENT_SLUG` was [introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/22864) in GitLab 8.15. > - The `name` and `url` keywords can use any of the defined CI variables, > including predefined, secure variables and `.gitlab-ci.yml` [`variables`](#variables). > You however can't use variables defined under `script`. For example: ```yaml deploy as review app: stage: deploy script: make deploy environment: name: review/$CI_COMMIT_REF_NAME url: https://$CI_ENVIRONMENT_SLUG.example.com/ ``` The `deploy as review app` job is marked as deployment to dynamically create the `review/$CI_COMMIT_REF_NAME` environment, where `$CI_COMMIT_REF_NAME` is an [environment variable](../variables/README.md) set by the runner. The `$CI_ENVIRONMENT_SLUG` variable is based on the environment name, but suitable for inclusion in URLs. In this case, if the `deploy as review app` job is run in a branch named `pow`, this environment would be accessible with an URL like `https://review-pow.example.com/`. This implies that the underlying server that hosts the application is properly configured. The common use case is to create dynamic environments for branches and use them as Review Apps. You can see a simple example using Review Apps at . ### `cache` > - Introduced in GitLab Runner v0.7.0. > - `cache` can be set globally and per-job. > - From GitLab 9.0, caching is enabled and shared between pipelines and jobs > by default. > - From GitLab 9.2, caches are restored before [artifacts](#artifacts). `cache` is used to specify a list of files and directories that should be cached between jobs. You can only use paths that are within the local working copy. If `cache` is defined outside the scope of jobs, it means it's set globally and all jobs use that definition. Read how caching works and find out some good practices in the [caching dependencies documentation](../caching/index.md). #### `cache:paths` Use the `paths` directive to choose which files or directories to cache. Paths are relative to the project directory (`$CI_PROJECT_DIR`) and can't directly link outside it. Wildcards can be used that follow the [glob](https://en.wikipedia.org/wiki/Glob_(programming)) patterns and: - In [GitLab Runner 13.0](https://gitlab.com/gitlab-org/gitlab-runner/-/issues/2620) and later, [`doublestar.Glob`](https://pkg.go.dev/github.com/bmatcuk/doublestar@v1.2.2?tab=doc#Match). - In GitLab Runner 12.10 and earlier, [`filepath.Match`](https://pkg.go.dev/path/filepath/#Match). Cache all files in `binaries` that end in `.apk` and the `.config` file: ```yaml rspec: script: test cache: paths: - binaries/*.apk - .config ``` Locally defined cache overrides globally defined options. The following `rspec` job caches only `binaries/`: ```yaml cache: paths: - my/files rspec: script: test cache: key: rspec paths: - binaries/ ``` The cache is shared between jobs, so if you're using different paths for different jobs, you should also set a different `cache:key`. Otherwise cache content can be overwritten. #### `cache:key` > Introduced in GitLab Runner v1.0.0. The `key` keyword defines the affinity of caching between jobs. You can have a single cache for all jobs, cache per-job, cache per-branch, or any other way that fits your workflow. This way, you can fine tune caching, including caching data between different jobs or even different branches. The `cache:key` variable can use any of the [predefined variables](../variables/README.md). The default key, if not set, is just literal `default`, which means everything is shared between pipelines and jobs by default, starting from GitLab 9.0. For example, to enable per-branch caching: ```yaml cache: key: "$CI_COMMIT_REF_SLUG" paths: - binaries/ ``` If you use **Windows Batch** to run your shell scripts you need to replace `$` with `%`: ```yaml cache: key: "%CI_COMMIT_REF_SLUG%" paths: - binaries/ ``` The `cache:key` variable can't contain the `/` character, or the equivalent URI-encoded `%2F`. A value made only of dots (`.`, `%2E`) is also forbidden. You can specify a [fallback cache key](#fallback-cache-key) to use if the specified `cache:key` is not found. #### Fallback cache key > [Introduced](https://gitlab.com/gitlab-org/gitlab-runner/-/merge_requests/1534) in GitLab Runner 13.4. You can use the `$CI_COMMIT_REF_SLUG` [variable](#variables) to specify your [`cache:key`](#cachekey). For example, if your `$CI_COMMIT_REF_SLUG` is `test` you can set a job to download cache that's tagged with `test`. If a cache with this tag is not found, you can use `CACHE_FALLBACK_KEY` to specify a cache to use when none exists. For example: ```yaml variables: CACHE_FALLBACK_KEY: fallback-key cache: key: "$CI_COMMIT_REF_SLUG" paths: - binaries/ ``` In this example, if the `$CI_COMMIT_REF_SLUG` is not found, the job uses the key defined by the `CACHE_FALLBACK_KEY` variable. ##### `cache:key:files` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/18986) in GitLab v12.5. The `cache:key:files` keyword extends the `cache:key` functionality by making it easier to reuse some caches, and rebuild them less often, which speeds up subsequent pipeline runs. When you include `cache:key:files`, you must also list the project files that are used to generate the key, up to a maximum of two files. The cache `key` is a SHA checksum computed from the most recent commits (up to two, if two files are listed) that changed the given files. If neither file was changed in any commits, the fallback key is `default`. ```yaml cache: key: files: - Gemfile.lock - package.json paths: - vendor/ruby - node_modules ``` In this example we're creating a cache for Ruby and Node.js dependencies that is tied to current versions of the `Gemfile.lock` and `package.json` files. Whenever one of these files changes, a new cache key is computed and a new cache is created. Any future job runs that use the same `Gemfile.lock` and `package.json` with `cache:key:files` use the new cache, instead of rebuilding the dependencies. ##### `cache:key:prefix` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/18986) in GitLab v12.5. When you want to combine a prefix with the SHA computed for `cache:key:files`, use the `prefix` keyword with `key:files`. For example, if you add a `prefix` of `test`, the resulting key is: `test-feef9576d21ee9b6a32e30c5c79d0a0ceb68d1e5`. If neither file was changed in any commits, the prefix is added to `default`, so the key in the example would be `test-default`. Like `cache:key`, `prefix` can use any of the [predefined variables](../variables/README.md), but the following are not allowed: - the `/` character (or the equivalent URI-encoded `%2F`) - a value made only of `.` (or the equivalent URI-encoded `%2E`) ```yaml cache: key: files: - Gemfile.lock prefix: ${CI_JOB_NAME} paths: - vendor/ruby rspec: script: - bundle exec rspec ``` For example, adding a `prefix` of `$CI_JOB_NAME` causes the key to look like: `rspec-feef9576d21ee9b6a32e30c5c79d0a0ceb68d1e5` and the job cache is shared across different branches. If a branch changes `Gemfile.lock`, that branch has a new SHA checksum for `cache:key:files`. A new cache key is generated, and a new cache is created for that key. If `Gemfile.lock` is not found, the prefix is added to `default`, so the key in the example would be `rspec-default`. #### `cache:untracked` Set `untracked: true` to cache all files that are untracked in your Git repository: ```yaml rspec: script: test cache: untracked: true ``` Cache all Git untracked files and files in `binaries`: ```yaml rspec: script: test cache: untracked: true paths: - binaries/ ``` #### `cache:when` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/18969) in GitLab 13.5 and GitLab Runner v13.5.0. `cache:when` defines when to save the cache, based on the status of the job. You can set `cache:when` to: - `on_success` - save the cache only when the job succeeds. This is the default. - `on_failure` - save the cache only when the job fails. - `always` - save the cache regardless of the job status. For example, to store a cache whether or not the job fails or succeeds: ```yaml rspec: script: rspec cache: paths: - rspec/ when: 'always' ``` #### `cache:policy` > Introduced in GitLab 9.4. The default behavior of a caching job is to download the files at the start of execution, and to re-upload them at the end. Any changes made by the job are persisted for future runs. This behavior is known as the `pull-push` cache policy. If you know the job does not alter the cached files, you can skip the upload step by setting `policy: pull` in the job specification. Typically, this would be twinned with an ordinary cache job at an earlier stage to ensure the cache is updated from time to time: ```yaml stages: - setup - test prepare: stage: setup cache: key: gems paths: - vendor/bundle script: - bundle install --deployment rspec: stage: test cache: key: gems paths: - vendor/bundle policy: pull script: - bundle exec rspec ... ``` This helps to speed up job execution and reduce load on the cache server. It is especially helpful when you have a large number of cache-using jobs executing in parallel. If you have a job that unconditionally recreates the cache without referring to its previous contents, you can skip the download step. To do so, add `policy: push` to the job. ### `artifacts` > - Introduced in GitLab Runner v0.7.0 for non-Windows platforms. > - Windows support was added in GitLab Runner v.1.0.0. > - From GitLab 9.2, caches are restored before artifacts. > - Not all executors are [supported](https://docs.gitlab.com/runner/executors/#compatibility-chart). > - Job artifacts are only collected for successful jobs by default. `artifacts` is used to specify a list of files and directories that are attached to the job when it [succeeds, fails, or always](#artifactswhen). The artifacts are sent to GitLab after the job finishes. They are available for download in the GitLab UI if the size is not larger than the [maximum artifact size](../../user/gitlab_com/index.md#gitlab-cicd). [Read more about artifacts](../pipelines/job_artifacts.md). #### `artifacts:paths` Paths are relative to the project directory (`$CI_PROJECT_DIR`) and can't directly link outside it. Wildcards can be used that follow the [glob](https://en.wikipedia.org/wiki/Glob_(programming)) patterns and: - In [GitLab Runner 13.0](https://gitlab.com/gitlab-org/gitlab-runner/-/issues/2620) and later, [`doublestar.Glob`](https://pkg.go.dev/github.com/bmatcuk/doublestar@v1.2.2?tab=doc#Match). - In GitLab Runner 12.10 and earlier, [`filepath.Match`](https://pkg.go.dev/path/filepath/#Match). To restrict which jobs a specific job fetches artifacts from, see [dependencies](#dependencies). Send all files in `binaries` and `.config`: ```yaml artifacts: paths: - binaries/ - .config ``` To disable artifact passing, define the job with empty [dependencies](#dependencies): ```yaml job: stage: build script: make build dependencies: [] ``` You may want to create artifacts only for tagged releases to avoid filling the build server storage with temporary build artifacts. Create artifacts only for tags (`default-job` doesn't create artifacts): ```yaml default-job: script: - mvn test -U except: - tags release-job: script: - mvn package -U artifacts: paths: - target/*.war only: - tags ``` You can use wildcards for directories too. For example, if you want to get all the files inside the directories that end with `xyz`: ```yaml job: artifacts: paths: - path/*xyz/* ``` #### `artifacts:exclude` > - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/15122) in GitLab 13.1 > - Requires GitLab Runner 13.1 `exclude` makes it possible to prevent files from being added to an artifacts archive. Similar to [`artifacts:paths`](#artifactspaths), `exclude` paths are relative to the project directory. Wildcards can be used that follow the [glob](https://en.wikipedia.org/wiki/Glob_(programming)) patterns and [`filepath.Match`](https://golang.org/pkg/path/filepath/#Match). For example, to store all files in `binaries/`, but not `*.o` files located in subdirectories of `binaries/`: ```yaml artifacts: paths: - binaries/ exclude: - binaries/**/*.o ``` Files matched by [`artifacts:untracked`](#artifactsuntracked) can be excluded using `artifacts:exclude` too. #### `artifacts:expose_as` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/15018) in GitLab 12.5. The `expose_as` keyword can be used to expose [job artifacts](../pipelines/job_artifacts.md) in the [merge request](../../user/project/merge_requests/index.md) UI. For example, to match a single file: ```yaml test: script: ["echo 'test' > file.txt"] artifacts: expose_as: 'artifact 1' paths: ['file.txt'] ``` With this configuration, GitLab adds a link **artifact 1** to the relevant merge request that points to `file1.txt`. An example that matches an entire directory: ```yaml test: script: ["mkdir test && echo 'test' > test/file.txt"] artifacts: expose_as: 'artifact 1' paths: ['test/'] ``` Note the following: - Artifacts do not display in the merge request UI when using variables to define the `artifacts:paths`. - A maximum of 10 job artifacts per merge request can be exposed. - Glob patterns are unsupported. - If a directory is specified, the link is to the job [artifacts browser](../pipelines/job_artifacts.md#browsing-artifacts) if there is more than one file in the directory. - For exposed single file artifacts with `.html`, `.htm`, `.txt`, `.json`, `.xml`, and `.log` extensions, if [GitLab Pages](../../administration/pages/index.md) is: - Enabled, GitLab automatically renders the artifact. - Not enabled, the file is displayed in the artifacts browser. #### `artifacts:name` > Introduced in GitLab 8.6 and GitLab Runner v1.1.0. Use the `name` directive to define the name of the created artifacts archive. You can specify a unique name for every archive, which can be useful when you want to download the archive from GitLab. The `artifacts:name` variable can make use of any of the [predefined variables](../variables/README.md). The default name is `artifacts`, which becomes `artifacts.zip` when you download it. To create an archive with a name of the current job: ```yaml job: artifacts: name: "$CI_JOB_NAME" paths: - binaries/ ``` To create an archive with a name of the current branch or tag including only the binaries directory: ```yaml job: artifacts: name: "$CI_COMMIT_REF_NAME" paths: - binaries/ ``` If your branch-name contains forward slashes (for example `feature/my-feature`) it's advised to use `$CI_COMMIT_REF_SLUG` instead of `$CI_COMMIT_REF_NAME` for proper naming of the artifact. To create an archive with a name of the current job and the current branch or tag including only the binaries directory: ```yaml job: artifacts: name: "$CI_JOB_NAME-$CI_COMMIT_REF_NAME" paths: - binaries/ ``` To create an archive with a name of the current [stage](#stages) and branch name: ```yaml job: artifacts: name: "$CI_JOB_STAGE-$CI_COMMIT_REF_NAME" paths: - binaries/ ``` --- If you use **Windows Batch** to run your shell scripts you need to replace `$` with `%`: ```yaml job: artifacts: name: "%CI_JOB_STAGE%-%CI_COMMIT_REF_NAME%" paths: - binaries/ ``` If you use **Windows PowerShell** to run your shell scripts you need to replace `$` with `$env:`: ```yaml job: artifacts: name: "$env:CI_JOB_STAGE-$env:CI_COMMIT_REF_NAME" paths: - binaries/ ``` #### `artifacts:untracked` `artifacts:untracked` is used to add all Git untracked files as artifacts (along to the paths defined in `artifacts:paths`). `artifacts:untracked` ignores configuration in the repository's `.gitignore` file. Send all Git untracked files: ```yaml artifacts: untracked: true ``` Send all Git untracked files and files in `binaries`: ```yaml artifacts: untracked: true paths: - binaries/ ``` Send all untracked files but [exclude](#artifactsexclude) `*.txt`: ```yaml artifacts: untracked: true exclude: - "*.txt" ``` #### `artifacts:when` > Introduced in GitLab 8.9 and GitLab Runner v1.3.0. `artifacts:when` is used to upload artifacts on job failure or despite the failure. `artifacts:when` can be set to one of the following values: 1. `on_success` - upload artifacts only when the job succeeds. This is the default. 1. `on_failure` - upload artifacts only when the job fails. 1. `always` - upload artifacts regardless of the job status. For example, to upload artifacts only when a job fails: ```yaml job: artifacts: when: on_failure ``` #### `artifacts:expire_in` > Introduced in GitLab 8.9 and GitLab Runner v1.3.0. Use `expire_in` to specify how long artifacts are active before they expire and are deleted. The expiration time period begins when the artifact is uploaded and stored on GitLab. If the expiry time is not defined, it defaults to the [instance wide setting](../../user/admin_area/settings/continuous_integration.md#default-artifacts-expiration) (30 days by default). To override the expiration date and protect artifacts from being automatically deleted: - Use the **Keep** button on the job page. - Set the value of `expire_in` to `never`. [Available](https://gitlab.com/gitlab-org/gitlab/-/issues/22761) in GitLab 13.3 and later. After their expiry, artifacts are deleted hourly by default (via a cron job), and are not accessible anymore. The value of `expire_in` is an elapsed time in seconds, unless a unit is provided. Examples of valid values: - `'42'` - `42 seconds` - `3 mins 4 sec` - `2 hrs 20 min` - `2h20min` - `6 mos 1 day` - `47 yrs 6 mos and 4d` - `3 weeks and 2 days` - `never` To expire artifacts 1 week after being uploaded: ```yaml job: artifacts: expire_in: 1 week ``` The latest artifacts for refs are locked against deletion, and kept regardless of the expiry time. [Introduced in](https://gitlab.com/gitlab-org/gitlab/-/issues/16267) GitLab 13.0 behind a disabled feature flag, and [made the default behavior](https://gitlab.com/gitlab-org/gitlab/-/issues/229936) in GitLab 13.4. #### `artifacts:reports` The [`artifacts:reports` keyword](../pipelines/job_artifacts.md#artifactsreports) is used for collecting test reports, code quality reports, and security reports from jobs. It also exposes these reports in GitLab's UI (merge requests, pipeline views, and security dashboards). These are the available report types: | Keyword | Description | |--------------------------------------------------------------------------------------------------------------------------------------|-------------| | [`artifacts:reports:cobertura`](../pipelines/job_artifacts.md#artifactsreportscobertura) | The `cobertura` report collects Cobertura coverage XML files. | | [`artifacts:reports:codequality`](../pipelines/job_artifacts.md#artifactsreportscodequality) | The `codequality` report collects CodeQuality issues. | | [`artifacts:reports:container_scanning`](../pipelines/job_artifacts.md#artifactsreportscontainer_scanning) **(ULTIMATE)** | The `container_scanning` report collects Container Scanning vulnerabilities. | | [`artifacts:reports:dast`](../pipelines/job_artifacts.md#artifactsreportsdast) **(ULTIMATE)** | The `dast` report collects Dynamic Application Security Testing vulnerabilities. | | [`artifacts:reports:dependency_scanning`](../pipelines/job_artifacts.md#artifactsreportsdependency_scanning) **(ULTIMATE)** | The `dependency_scanning` report collects Dependency Scanning vulnerabilities. | | [`artifacts:reports:dotenv`](../pipelines/job_artifacts.md#artifactsreportsdotenv) | The `dotenv` report collects a set of environment variables. | | [`artifacts:reports:junit`](../pipelines/job_artifacts.md#artifactsreportsjunit) | The `junit` report collects JUnit XML files. | | [`artifacts:reports:license_management`](../pipelines/job_artifacts.md#artifactsreportslicense_management) **(ULTIMATE)** | The `license_management` report collects Licenses (*removed from GitLab 13.0*). | | [`artifacts:reports:license_scanning`](../pipelines/job_artifacts.md#artifactsreportslicense_scanning) **(ULTIMATE)** | The `license_scanning` report collects Licenses. | | [`artifacts:reports:load_performance`](../pipelines/job_artifacts.md#artifactsreportsload_performance) **(PREMIUM)** | The `load_performance` report collects load performance metrics. | | [`artifacts:reports:metrics`](../pipelines/job_artifacts.md#artifactsreportsmetrics) **(PREMIUM)** | The `metrics` report collects Metrics. | | [`artifacts:reports:performance`](../pipelines/job_artifacts.md#artifactsreportsperformance) **(PREMIUM)** | The `performance` report collects Browser Performance metrics. | | [`artifacts:reports:sast`](../pipelines/job_artifacts.md#artifactsreportssast) **(ULTIMATE)** | The `sast` report collects Static Application Security Testing vulnerabilities. | | [`artifacts:reports:terraform`](../pipelines/job_artifacts.md#artifactsreportsterraform) | The `terraform` report collects Terraform `tfplan.json` files. | #### `dependencies` > Introduced in GitLab 8.6 and GitLab Runner v1.1.1. By default, all [`artifacts`](#artifacts) from previous [stages](#stages) are passed to each job. However, you can use the `dependencies` keyword to define a limited list of jobs to fetch artifacts from. You can also set a job to download no artifacts at all. To use this feature, define `dependencies` in context of the job and pass a list of all previous jobs the artifacts should be downloaded from. You can define jobs from stages that were executed before the current one. An error occurs if you define jobs from the current or an upcoming stage. To prevent a job from downloading artifacts, define an empty array. When you use `dependencies`, the status of the previous job is not considered. If a job fails or it's a manual job that was not run, no error occurs. The following example defines two jobs with artifacts: `build:osx` and `build:linux`. When the `test:osx` is executed, the artifacts from `build:osx` are downloaded and extracted in the context of the build. The same happens for `test:linux` and artifacts from `build:linux`. The job `deploy` downloads artifacts from all previous jobs because of the [stage](#stages) precedence: ```yaml build:osx: stage: build script: make build:osx artifacts: paths: - binaries/ build:linux: stage: build script: make build:linux artifacts: paths: - binaries/ test:osx: stage: test script: make test:osx dependencies: - build:osx test:linux: stage: test script: make test:linux dependencies: - build:linux deploy: stage: deploy script: make deploy ``` ##### When a dependent job fails > Introduced in GitLab 10.3. If the artifacts of the job that is set as a dependency have been [expired](#artifactsexpire_in) or [erased](../pipelines/job_artifacts.md#erasing-artifacts), then the dependent job fails. You can ask your administrator to [flip this switch](../../administration/job_artifacts.md#validation-for-dependencies) and bring back the old behavior. ### `coverage` > [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/20428) in GitLab 8.17. Use `coverage` to configure how code coverage is extracted from the job output. Regular expressions are the only valid kind of value expected here. So, using surrounding `/` is mandatory to consistently and explicitly represent a regular expression string. You must escape special characters if you want to match them literally. A simple example: ```yaml job1: script: rspec coverage: '/Code coverage: \d+\.\d+/' ``` ### `retry` > - [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/3442) in GitLab 9.5. > - [Behavior expanded](https://gitlab.com/gitlab-org/gitlab-runner/-/issues/3515) in GitLab 11.5 to control which failures to retry on. Use `retry` to configure how many times a job is retried in case of a failure. When a job fails, the job is processed again, until the limit specified by the `retry` keyword is reached. If `retry` is set to `2`, and a job succeeds in a second run (first retry), it is not retried. The `retry` value must be a positive integer, from `0` to `2` (two retries maximum, three runs in total). This example retries all failure cases: ```yaml test: script: rspec retry: 2 ``` By default, a job is retried on all failure cases. To have better control over which failures to retry, `retry` can be a hash with the following keys: - `max`: The maximum number of retries. - `when`: The failure cases to retry. To retry only runner system failures at maximum two times: ```yaml test: script: rspec retry: max: 2 when: runner_system_failure ``` If there is another failure, other than a runner system failure, the job is not retried. To retry on multiple failure cases, `when` can also be an array of failures: ```yaml test: script: rspec retry: max: 2 when: - runner_system_failure - stuck_or_timeout_failure ``` Possible values for `when` are: - `always`: Retry on any failure (default). - `unknown_failure`: Retry when the failure reason is unknown. - `script_failure`: Retry when the script failed. - `api_failure`: Retry on API failure. - `stuck_or_timeout_failure`: Retry when the job got stuck or timed out. - `runner_system_failure`: Retry if there was a runner system failure (for example, job setup failed). - `missing_dependency_failure`: Retry if a dependency was missing. - `runner_unsupported`: Retry if the runner was unsupported. - `stale_schedule`: Retry if a delayed job could not be executed. - `job_execution_timeout`: Retry if the script exceeded the maximum execution time set for the job. - `archived_failure`: Retry if the job is archived and can't be run. - `unmet_prerequisites`: Retry if the job failed to complete prerequisite tasks. - `scheduler_failure`: Retry if the scheduler failed to assign the job to a runner. - `data_integrity_failure`: Retry if there was a structural integrity problem detected. You can specify the number of [retry attempts for certain stages of job execution](../runners/README.md#job-stages-attempts) using variables. ### `timeout` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/14887) in GitLab 12.3. Use `timeout` to configure a timeout for a specific job. For example: ```yaml build: script: build.sh timeout: 3 hours 30 minutes test: script: rspec timeout: 3h 30m ``` The job-level timeout can exceed the [project-level timeout](../pipelines/settings.md#timeout) but can't exceed the runner-specific timeout. ### `parallel` > [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/21480) in GitLab 11.5. Use `parallel` to configure how many instances of a job to run in parallel. This value can be from 2 to 50. This creates N instances of the same job that run in parallel. They are named sequentially from `job_name 1/N` to `job_name N/N`. For every job, `CI_NODE_INDEX` and `CI_NODE_TOTAL` [environment variables](../variables/README.md#predefined-environment-variables) are set. Marking a job to be run in parallel requires adding `parallel` to your configuration file. For example: ```yaml test: script: rspec parallel: 5 ``` Parallelize tests suites across parallel jobs. Different languages have different tools to facilitate this. A simple example using [Semaphore Test Boosters](https://github.com/renderedtext/test-boosters) and RSpec to run some Ruby tests: ```ruby # Gemfile source 'https://rubygems.org' gem 'rspec' gem 'semaphore_test_boosters' ``` ```yaml test: parallel: 3 script: - bundle - bundle exec rspec_booster --job $CI_NODE_INDEX/$CI_NODE_TOTAL ``` CAUTION: **Caution:** Please be aware that semaphore_test_boosters reports usages statistics to the author. You can then navigate to the **Jobs** tab of a new pipeline build and see your RSpec job split into three separate jobs. #### Parallel `matrix` jobs > - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/15356) in GitLab 13.3. Use `matrix:` to configure different variables for jobs that are running in parallel. There can be from 2 to 50 jobs. [In GitLab 13.5](https://gitlab.com/gitlab-org/gitlab/-/issues/26362) and later, you can have one-dimensional matrices with a single job. Every job gets the same `CI_NODE_TOTAL` [environment variable](../variables/README.md#predefined-environment-variables) value, and a unique `CI_NODE_INDEX` value. ```yaml deploystacks: stage: deploy script: - bin/deploy parallel: matrix: - PROVIDER: aws STACK: - monitoring - app1 - app2 - PROVIDER: ovh STACK: [monitoring, backup, app] - PROVIDER: [gcp, vultr] STACK: [data, processing] ``` This generates 10 parallel `deploystacks` jobs, each with different values for `PROVIDER` and `STACK`: ```plaintext deploystacks: [aws, monitoring] deploystacks: [aws, app1] deploystacks: [aws, app2] deploystacks: [ovh, monitoring] deploystacks: [ovh, backup] deploystacks: [ovh, app] deploystacks: [gcp, data] deploystacks: [gcp, processing] deploystacks: [vultr, data] deploystacks: [vultr, processing] ``` Job naming style [was improved](https://gitlab.com/gitlab-org/gitlab/-/issues/230452) in GitLab 13.4. ### `trigger` > - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/8997) in [GitLab Premium](https://about.gitlab.com/pricing/) 11.8. > - [Moved](https://gitlab.com/gitlab-org/gitlab/-/issues/199224) to GitLab Core in 12.8. Use `trigger` to define a downstream pipeline trigger. When GitLab starts a job created with a `trigger` definition, a downstream pipeline is created. Jobs with `trigger` can only use a [limited set of keywords](../multi_project_pipelines.md#limitations). For example, you can't run commands with [`script`](#script), [`before_script`](#before_script), or [`after_script`](#after_script). You can use this keyword to create two different types of downstream pipelines: - [Multi-project pipelines](../multi_project_pipelines.md#creating-multi-project-pipelines-from-gitlab-ciyml) - [Child pipelines](../parent_child_pipelines.md) [In GitLab 13.2](https://gitlab.com/gitlab-org/gitlab/-/issues/197140/) and later, you can view which job triggered a downstream pipeline. In the [pipeline graph](../pipelines/index.md#visualize-pipelines), hover over the downstream pipeline job. In [GitLab 13.5](https://gitlab.com/gitlab-org/gitlab/-/issues/201938) and later, you can use [`when:manual`](#whenmanual) in the same job as `trigger`. In GitLab 13.4 and earlier, using them together causes the error `jobs:#{job-name} when should be on_success, on_failure or always`. It is deployed behind the `:ci_manual_bridges` [feature flag](../../user/feature_flags.md), which is **enabled by default**. [GitLab administrators with access to the Rails console](../../administration/feature_flags.md) can opt to disable it. #### Simple `trigger` syntax for multi-project pipelines The simplest way to configure a downstream trigger is to use `trigger` keyword with a full path to a downstream project: ```yaml rspec: stage: test script: bundle exec rspec staging: stage: deploy trigger: my/deployment ``` #### Complex `trigger` syntax for multi-project pipelines You can configure a branch name that GitLab uses to create a downstream pipeline with: ```yaml rspec: stage: test script: bundle exec rspec staging: stage: deploy trigger: project: my/deployment branch: stable ``` To mirror the status from a triggered pipeline: ```yaml trigger_job: trigger: project: my/project strategy: depend ``` To mirror the status from an upstream pipeline: ```yaml upstream_bridge: stage: test needs: pipeline: other/project ``` #### `trigger` syntax for child pipeline > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/16094) in GitLab 12.7. To create a [child pipeline](../parent_child_pipelines.md), specify the path to the YAML file containing the CI config of the child pipeline: ```yaml trigger_job: trigger: include: path/to/child-pipeline.yml ``` Similar to [multi-project pipelines](../multi_project_pipelines.md#mirroring-status-from-triggered-pipeline), it's possible to mirror the status from a triggered pipeline: ```yaml trigger_job: trigger: include: - local: path/to/child-pipeline.yml strategy: depend ``` ##### Trigger child pipeline with generated configuration file > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/35632) in GitLab 12.9. You can also trigger a child pipeline from a [dynamically generated configuration file](../parent_child_pipelines.md#dynamic-child-pipelines): ```yaml generate-config: stage: build script: generate-ci-config > generated-config.yml artifacts: paths: - generated-config.yml child-pipeline: stage: test trigger: include: - artifact: generated-config.yml job: generate-config ``` The `generated-config.yml` is extracted from the artifacts and used as the configuration for triggering the child pipeline. ##### Trigger child pipeline with files from another project > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/205157) in GitLab 13.5. To trigger child pipelines with files from another private project under the same GitLab instance, use [`include:file`](#includefile): ```yaml child-pipeline: trigger: include: - project: 'my-group/my-pipeline-library' ref: 'master' file: '/path/to/child-pipeline.yml' ``` #### Linking pipelines with `trigger:strategy` By default, the `trigger` job completes with the `success` status as soon as the downstream pipeline is created. To force the `trigger` job to wait for the downstream (multi-project or child) pipeline to complete, use `strategy: depend`. This setting makes the trigger job wait with a "running" status until the triggered pipeline completes. At that point, the `trigger` job completes and displays the same status as the downstream job. ```yaml trigger_job: trigger: include: path/to/child-pipeline.yml strategy: depend ``` This setting can help keep your pipeline execution linear. In the example above, jobs from subsequent stages wait for the triggered pipeline to successfully complete before starting, which reduces parallelization. #### Trigger a pipeline by API call To force a rebuild of a specific branch, tag, or commit, you can use an API call with a trigger token. The trigger token is different than the [`trigger`](#trigger) keyword. [Read more in the triggers documentation.](../triggers/README.md) ### `interruptible` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/32022) in GitLab 12.3. `interruptible` is used to indicate that a job should be canceled if made redundant by a newer pipeline run. Defaults to `false`. This value is used only if the [automatic cancellation of redundant pipelines feature](../pipelines/settings.md#auto-cancel-pending-pipelines) is enabled. When enabled, a pipeline on the same branch is canceled when: - It's made redundant by a newer pipeline run. - Either all jobs are set as interruptible, or any uninterruptible jobs haven't started. Set jobs as interruptible that can be safely canceled once started (for instance, a build job). Pending jobs are always considered interruptible. Here is a simple example: ```yaml stages: - stage1 - stage2 - stage3 step-1: stage: stage1 script: - echo "Can be canceled." interruptible: true step-2: stage: stage2 script: - echo "Can not be canceled." step-3: stage: stage3 script: - echo "Because step-2 can not be canceled, this step can never be canceled, even though it's set as interruptible." interruptible: true ``` In the example above, a new pipeline run causes an existing running pipeline to be: - Canceled, if only `step-1` is running or pending. - Not canceled, once `step-2` starts running. When an uninterruptible job is running, the pipeline can never be canceled, regardless of the final job's state. ### `resource_group` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/15536) in GitLab 12.7. Sometimes running multiple jobs or pipelines at the same time in an environment can lead to errors during the deployment. To avoid these errors, the `resource_group` attribute can be used to ensure that the runner doesn't run certain jobs simultaneously. Resource groups behave similar to semaphores in other programming languages. When the `resource_group` key is defined for a job in `.gitlab-ci.yml`, job executions are mutually exclusive across different pipelines for the same project. If multiple jobs belonging to the same resource group are enqueued simultaneously, only one of the jobs is picked by the runner. The other jobs wait until the `resource_group` is free. Here is a simple example: ```yaml deploy-to-production: script: deploy resource_group: production ``` In this case, two `deploy-to-production` jobs in two separate pipelines can never run at the same time. As a result, you can ensure that concurrent deployments never happen to the production environment. There can be multiple `resource_group`s defined per environment. A good use case for this is when deploying to physical devices. You may have multiple physical devices that can be deployed to, but there can be only one deployment per device at any given time. The `resource_group` value can only contain letters, digits, `-`, `_`, `/`, `$`, `{`, `}`, `.`, and spaces. It can't start or end with `/`. For more information, see [Deployments Safety](../environments/deployment_safety.md). ### `release` > [Introduced](https://gitlab.com/gitlab-org/gitlab/merge_requests/19298) in GitLab 13.2. `release` indicates that the job creates a [Release](../../user/project/releases/index.md). These methods are supported: - [`tag_name`](#releasetag_name) - [`description`](#releasedescription) - [`name`](#releasename) (optional) - [`ref`](#releaseref) (optional) - [`milestones`](#releasemilestones) (optional) - [`released_at`](#releasereleased_at) (optional) The Release is created only if the job processes without error. If the Rails API returns an error during Release creation, the `release` job fails. #### `release-cli` Docker image The Docker image to use for the `release-cli` must be specified, using the following directive: ```yaml image: registry.gitlab.com/gitlab-org/release-cli:latest ``` #### Script All jobs require a `script` tag at a minimum. A `:release` job can use the output of a `:script` tag, but if this is not necessary, a placeholder script can be used, for example: ```yaml script: - echo 'release job' ``` An [issue](https://gitlab.com/gitlab-org/gitlab/-/issues/223856) exists to remove this requirement in an upcoming version of GitLab. A pipeline can have multiple `release` jobs, for example: ```yaml ios-release: script: - echo 'iOS release job' release: tag_name: v1.0.0-ios description: 'iOS release v1.0.0' android-release: script: - echo 'Android release job' release: tag_name: v1.0.0-android description: 'Android release v1.0.0' ``` #### `release:tag_name` The `tag_name` must be specified. It can refer to an existing Git tag or can be specified by the user. When the specified tag doesn't exist in the repository, a new tag is created from the associated SHA of the pipeline. For example, when creating a Release from a Git tag: ```yaml job: release: tag_name: $CI_COMMIT_TAG description: 'Release description' ``` It is also possible to create any unique tag, in which case `only: tags` is not mandatory. A semantic versioning example: ```yaml job: release: tag_name: ${MAJOR}_${MINOR}_${REVISION} description: 'Release description' ``` - The Release is created only if the job's main script succeeds. - If the Release already exists, it is not updated and the job with the `release` keyword fails. - The `release` section executes after the `script` tag and before the `after_script`. #### `release:name` The Release name. If omitted, it is populated with the value of `release: tag_name`. #### `release:description` Specifies the longer description of the Release. #### `release:ref` If the `release: tag_name` doesn’t exist yet, the release is created from `ref`. `ref` can be a commit SHA, another tag name, or a branch name. #### `release:milestones` The title of each milestone the release is associated with. #### `release:released_at` The date and time when the release is ready. Defaults to the current date and time if not defined. Should be enclosed in quotes and expressed in ISO 8601 format. ```json released_at: '2021-03-15T08:00:00Z' ``` #### Complete example for `release` Combining the individual examples given above for `release` results in the following code snippets. There are two options, depending on how you generate the tags. These options cannot be used together, so choose one: - To create a release when you push a Git tag, or when you add a Git tag in the UI by going to **Repository > Tags**: ```yaml release_job: stage: release image: registry.gitlab.com/gitlab-org/release-cli:latest rules: - if: $CI_COMMIT_TAG # Run this job when a tag is created manually script: - echo 'running release_job' release: name: 'Release $CI_COMMIT_TAG' description: 'Created using the release-cli $EXTRA_DESCRIPTION' # $EXTRA_DESCRIPTION must be defined tag_name: '$CI_COMMIT_TAG' # elsewhere in the pipeline. ref: '$CI_COMMIT_TAG' milestones: - 'm1' - 'm2' - 'm3' released_at: '2020-07-15T08:00:00Z' # Optional, is auto generated if not defined, or can use a variable. ``` - To create a release automatically when commits are pushed or merged to the default branch, using a new Git tag that is defined with variables: NOTE: **Note:** Environment variables set in `before_script` or `script` are not available for expanding in the same job. Read more about [potentially making variables available for expanding](https://gitlab.com/gitlab-org/gitlab-runner/-/issues/6400). ```yaml prepare_job: stage: prepare # This stage must run before the release stage rules: - if: $CI_COMMIT_TAG when: never # Do not run this job when a tag is created manually - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH # Run this job when commits are pushed or merged to the default branch script: - echo "EXTRA_DESCRIPTION=some message" >> variables.env # Generate the EXTRA_DESCRIPTION and TAG environment variables - echo "TAG=v$(cat VERSION)" >> variables.env # and append to the variables.env file artifacts: reports: dotenv: variables.env # Use artifacts:reports:dotenv to expose the variables to other jobs release_job: stage: release image: registry.gitlab.com/gitlab-org/release-cli:latest needs: - job: prepare_job artifacts: true rules: - if: $CI_COMMIT_TAG when: never # Do not run this job when a tag is created manually - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH # Run this job when commits are pushed or merged to the default branch script: - echo 'running release_job for $TAG' release: name: 'Release $TAG' description: 'Created using the release-cli $EXTRA_DESCRIPTION' # $EXTRA_DESCRIPTION and the $TAG tag_name: '$TAG' # variables must be defined elsewhere ref: '$CI_COMMIT_SHA' # in the pipeline. For example, in the milestones: # prepare_job - 'm1' - 'm2' - 'm3' released_at: '2020-07-15T08:00:00Z' # Optional, is auto generated if not defined, or can use a variable. ``` #### Release assets as Generic packages You can use [Generic packages](../../user/packages/generic_packages/) to host your release assets. For a complete example of how to do this, see the [example in the repository](https://gitlab.com/gitlab-org/release-cli/-/tree/master/docs/examples/release-assets-as-generic-package/). #### `releaser-cli` command line The entries under the `:release` node are transformed into a `bash` command line and sent to the Docker container, which contains the [release-cli](https://gitlab.com/gitlab-org/release-cli). You can also call the `release-cli` directly from a `script` entry. The YAML described above would be translated into a CLI command like this: ```shell release-cli create --name "Release $CI_COMMIT_SHA" --description "Created using the release-cli $EXTRA_DESCRIPTION" --tag-name "v${MAJOR}.${MINOR}.${REVISION}" --ref "$CI_COMMIT_SHA" --released-at "2020-07-15T08:00:00Z" --milestone "m1" --milestone "m2" --milestone "m3" ``` ### `secrets` > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/33014) in GitLab 13.4. `secrets` indicates the [CI Secrets](../secrets/index.md) this job needs. It should be a hash, and the keys should be the names of the environment variables that are made available to the job. The value of each secret is saved in a temporary file. This file's path is stored in these environment variables. #### `secrets:vault` **(PREMIUM)** > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/28321) in GitLab 13.4. `vault` keyword specifies secrets provided by [Hashicorp's Vault](https://www.vaultproject.io/). This syntax has multiple forms. The shortest form assumes the use of the [KV-V2](https://www.vaultproject.io/docs/secrets/kv/kv-v2) secrets engine, mounted at the default path `kv-v2`. The last part of the secret's path is the field to fetch the value for: ```yaml job: secrets: DATABASE_PASSWORD: vault: production/db/password # translates to secret `kv-v2/data/production/db`, field `password` ``` You can specify a custom secrets engine path by adding a suffix starting with `@`: ```yaml job: secrets: DATABASE_PASSWORD: vault: production/db/password@ops # translates to secret `ops/data/production/db`, field `password` ``` In the detailed form of the syntax, you can specify all details explicitly: ```yaml job: secrets: DATABASE_PASSWORD: # translates to secret `ops/data/production/db`, field `password` vault: engine: name: kv-v2 path: ops path: production/db field: password ``` ### `pages` `pages` is a special job that is used to upload static content to GitLab that can be used to serve your website. It has a special syntax, so the two requirements below must be met: - Any static content must be placed under a `public/` directory. - `artifacts` with a path to the `public/` directory must be defined. The example below simply moves all files from the root of the project to the `public/` directory. The `.public` workaround is so `cp` does not also copy `public/` to itself in an infinite loop: ```yaml pages: stage: deploy script: - mkdir .public - cp -r * .public - mv .public public artifacts: paths: - public only: - master ``` Read more on [GitLab Pages user documentation](../../user/project/pages/index.md). ## `variables` > Introduced in GitLab Runner v0.5.0. [CI/CD variables](../variables/README.md) are configurable values that are passed to jobs. They can be set globally and per-job. There are two types of variables. - [Custom variables](../variables/README.md#custom-environment-variables): You can define their values in the `.gitlab-ci.yml` file, in the GitLab UI, or by using the API. - [Predefined variables](../variables/predefined_variables.md): These values are set by the runner itself. One example is `CI_COMMIT_REF_NAME`, which is the branch or tag the project is built for. After you define a variable, you can use it in all executed commands and scripts. Variables are meant for non-sensitive project configuration, for example: ```yaml variables: DEPLOY_SITE: "https://example.com/" deploy_job: stage: deploy script: - deploy-script --url $DEPLOY_SITE --path "/" deploy_review_job: stage: deploy variables: REVIEW_PATH: "/review" script: - deploy-review-script --url $DEPLOY_SITE --path $REVIEW_PATH ``` You can use only integers and strings for the variable's name and value. If you define a variable at the top level of the `gitlab-ci.yml` file, it is global, meaning it applies to all jobs. If you define a variable within a job, it's available to that job only. If a variable of the same name is defined globally and for a specific job, the [job-specific variable is used](../variables/README.md#priority-of-environment-variables). All YAML-defined variables are also set to any linked [Docker service containers](../docker/using_docker_images.md#what-is-a-service). You can use [YAML anchors for variables](#yaml-anchors-for-variables). ### Configure runner behavior with variables You can use [CI/CD variables](../variables/README.md) to configure runner Git behavior: - [`GIT_STRATEGY`](../runners/README.md#git-strategy) - [`GIT_SUBMODULE_STRATEGY`](../runners/README.md#git-submodule-strategy) - [`GIT_CHECKOUT`](../runners/README.md#git-checkout) - [`GIT_CLEAN_FLAGS`](../runners/README.md#git-clean-flags) - [`GIT_FETCH_EXTRA_FLAGS`](../runners/README.md#git-fetch-extra-flags) - [`GIT_DEPTH`](../runners/README.md#shallow-cloning) (shallow cloning) - [`GIT_CLONE_PATH`](../runners/README.md#custom-build-directories) (custom build directories) You can also use variables to configure how many times a runner [attempts certain stages of job execution](../runners/README.md#job-stages-attempts). ## Special YAML features It's possible to use special YAML features like anchors (`&`), aliases (`*`) and map merging (`<<`). Use these features to reduce the complexity of `.gitlab-ci.yml`. Read more about the various [YAML features](https://learnxinyminutes.com/docs/yaml/). In most cases, the [`extends` keyword](#extends) is more user friendly and should be used over these special YAML features. YAML anchors may still need to be used to merge arrays. ### Anchors > Introduced in GitLab 8.6 and GitLab Runner v1.1.1. YAML has a feature called 'anchors' that you can use to duplicate content across your document. Use anchors to duplicate or inherit properties. Use anchors with [hidden jobs](#hide-jobs) to provide templates for your jobs. When there are duplicate keys, GitLab performs a reverse deep merge based on the keys. You can't use YAML anchors across multiple files when leveraging the [`include`](#include) feature. Anchors are only valid within the file they were defined in. Instead of using YAML anchors, you can use the [`extends` keyword](#extends). The following example uses anchors and map merging. It creates two jobs, `test1` and `test2`, that inherit the `.job_template` configuration, each with their own custom `script` defined: ```yaml .job_template: &job_definition # Hidden key that defines an anchor named 'job_definition' image: ruby:2.6 services: - postgres - redis test1: <<: *job_definition # Merge the contents of the 'job_definition' alias script: - test1 project test2: <<: *job_definition # Merge the contents of the 'job_definition' alias script: - test2 project ``` `&` sets up the name of the anchor (`job_definition`), `<<` means "merge the given hash into the current one", and `*` includes the named anchor (`job_definition` again). The expanded version looks like this: ```yaml .job_template: image: ruby:2.6 services: - postgres - redis test1: image: ruby:2.6 services: - postgres - redis script: - test1 project test2: image: ruby:2.6 services: - postgres - redis script: - test2 project ``` Let's see another example. This time we use anchors to define two sets of services. This configuration creates two jobs, `test:postgres` and `test:mysql`, that share the `script` directive defined in `.job_template`, and the `services` directive defined in `.postgres_services` and `.mysql_services` respectively: ```yaml .job_template: &job_definition script: - test project tags: - dev .postgres_services: services: &postgres_definition - postgres - ruby .mysql_services: services: &mysql_definition - mysql - ruby test:postgres: <<: *job_definition services: *postgres_definition tags: - postgres test:mysql: <<: *job_definition services: *mysql_definition ``` The expanded version looks like this: ```yaml .job_template: script: - test project tags: - dev .postgres_services: services: - postgres - ruby .mysql_services: services: - mysql - ruby test:postgres: script: - test project services: - postgres - ruby tags: - postgres test:mysql: script: - test project services: - mysql - ruby tags: - dev ``` You can see that the hidden jobs are conveniently used as templates, and `tags: [dev]` has been overwritten by `tags: [postgres]`. #### YAML anchors for scripts > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/23005) in GitLab 12.5. You can use [YAML anchors](#anchors) with [script](#script), [`before_script`](#before_script), and [`after_script`](#after_script) to use predefined commands in multiple jobs: ```yaml .some-script: &some-script - echo "Execute this in `before_script` sections" .some-script-before: &some-script-before - echo "Execute this in `script` sections" .some-script-after: &some-script-after - echo "Execute this in `after_script` sections" job_name: before_script: - *some-script-before script: - *some-script before_script: - *some-script-after ``` #### YAML anchors for variables [YAML anchors](#anchors) can be used with `variables`, to easily repeat assignment of variables across multiple jobs. It can also enable more flexibility when a job requires a specific `variables` block that would otherwise override the global variables. In the example below, we override the `GIT_STRATEGY` variable without affecting the use of the `SAMPLE_VARIABLE` variable: ```yaml # global variables variables: &global-variables SAMPLE_VARIABLE: sample_variable_value ANOTHER_SAMPLE_VARIABLE: another_sample_variable_value # a job that must set the GIT_STRATEGY variable, yet depend on global variables job_no_git_strategy: stage: cleanup variables: <<: *global-variables GIT_STRATEGY: none script: echo $SAMPLE_VARIABLE ``` ### Hide jobs > Introduced in GitLab 8.6 and GitLab Runner v1.1.1. If you want to temporarily 'disable' a job, rather than commenting out all the lines where the job is defined: ```yaml # hidden_job: # script: # - run test ``` Instead, you can start its name with a dot (`.`) and it is not processed by GitLab CI/CD. In the following example, `.hidden_job` is ignored: ```yaml .hidden_job: script: - run test ``` Use this feature to ignore jobs, or use the [special YAML features](#special-yaml-features) and transform the hidden jobs into templates. ## Skip Pipeline If your commit message contains `[ci skip]` or `[skip ci]`, using any capitalization, the commit is created but the pipeline is skipped. Alternatively, one can pass the `ci.skip` [Git push option](../../user/project/push_options.md#push-options-for-gitlab-cicd) if using Git 2.10 or newer. ## Processing Git pushes GitLab creates at most four branch and tag pipelines when pushing multiple changes in a single `git push` invocation. This limitation does not affect any of the updated merge request pipelines. All updated merge requests have a pipeline created when using [pipelines for merge requests](../merge_request_pipelines/index.md). ## Deprecated keywords The following keywords are deprecated. ### Globally-defined `types` DANGER: **Deprecated:** `types` is deprecated, and could be removed in a future release. Use [`stages`](#stages) instead. ### Job-defined `type` DANGER: **Deprecated:** `type` is deprecated, and could be removed in one of the future releases. Use [`stage`](#stage) instead. ### Globally-defined `image`, `services`, `cache`, `before_script`, `after_script` Defining `image`, `services`, `cache`, `before_script`, and `after_script` globally is deprecated. Support could be removed from a future release. Use [`default:`](#global-defaults) instead. For example: ```yaml default: image: ruby:2.5 services: - docker:dind cache: paths: [vendor/] before_script: - bundle install --path vendor/ after_script: - rm -rf tmp/ ```
