# GitLab CI/CD include examples **(FREE)**
|
|
|
|
You can use [`include`](index.md#include) to include external YAML files in your CI/CD jobs.
|
|
|
|
## Include a single configuration file
|
|
|
|
To include a single configuration file, use either of these syntax options:
|
|
|
|
- `include` by itself with a single file, which is the same as
|
|
[`include:local`](index.md#includelocal):
|
|
|
|
```yaml
|
|
include: '/templates/.after-script-template.yml'
|
|
```
|
|
|
|
- `include` with a single file, and you specify the `include` type:
|
|
|
|
```yaml
|
|
include:
|
|
remote: 'https://gitlab.com/awesome-project/raw/main/.before-script-template.yml'
|
|
```
|
|
|
|
## Include an array of configuration files
|
|
|
|
You can include an array of configuration files:
|
|
|
|
- If you do not specify an `include` type, the type defaults to [`include:local`](index.md#includelocal):
|
|
|
|
```yaml
|
|
include:
|
|
- 'https://gitlab.com/awesome-project/raw/main/.before-script-template.yml'
|
|
- '/templates/.after-script-template.yml'
|
|
```
|
|
|
|
- You can define a single item array:
|
|
|
|
```yaml
|
|
include:
|
|
- remote: 'https://gitlab.com/awesome-project/raw/main/.before-script-template.yml'
|
|
```
|
|
|
|
- You can define an array and explicitly specify multiple `include` types:
|
|
|
|
```yaml
|
|
include:
|
|
- remote: 'https://gitlab.com/awesome-project/raw/main/.before-script-template.yml'
|
|
- local: '/templates/.after-script-template.yml'
|
|
- template: Auto-DevOps.gitlab-ci.yml
|
|
```
|
|
|
|
- You can define an array that combines both default and specific `include` type:
|
|
|
|
```yaml
|
|
include:
|
|
- 'https://gitlab.com/awesome-project/raw/main/.before-script-template.yml'
|
|
- '/templates/.after-script-template.yml'
|
|
- template: Auto-DevOps.gitlab-ci.yml
|
|
- project: 'my-group/my-project'
|
|
ref: main
|
|
file: '/templates/.gitlab-ci-template.yml'
|
|
```
|
|
|
|
## Use `default` configuration from an included configuration file
|
|
|
|
You can define a [`default`](index.md#default) section in a
|
|
configuration file. When you use a `default` section with the `include` keyword, the defaults apply to
|
|
all jobs in the pipeline.
|
|
|
|
For example, you can use a `default` section with [`before_script`](index.md#before_script).
|
|
|
|
Content of a custom configuration file named `/templates/.before-script-template.yml`:
|
|
|
|
```yaml
|
|
default:
|
|
before_script:
|
|
- apt-get update -qq && apt-get install -y -qq sqlite3 libsqlite3-dev nodejs
|
|
- gem install bundler --no-document
|
|
- bundle install --jobs $(nproc) "${FLAGS[@]}"
|
|
```
|
|
|
|
Content of `.gitlab-ci.yml`:
|
|
|
|
```yaml
|
|
include: '/templates/.before-script-template.yml'
|
|
|
|
rspec1:
|
|
script:
|
|
- bundle exec rspec
|
|
|
|
rspec2:
|
|
script:
|
|
- bundle exec rspec
|
|
```
|
|
|
|
The default `before_script` commands execute in both `rspec` jobs, before the `script` commands.
|
|
|
|
## Override included configuration values
|
|
|
|
When you use the `include` keyword, you can override the included configuration values to adapt them
|
|
to your pipeline requirements.
|
|
|
|
The following example shows an `include` file that is customized in the
|
|
`.gitlab-ci.yml` file. Specific YAML-defined variables and details of the
|
|
`production` job are overridden.
|
|
|
|
Content of a custom configuration file named `autodevops-template.yml`:
|
|
|
|
```yaml
|
|
variables:
|
|
POSTGRES_USER: user
|
|
POSTGRES_PASSWORD: testing_password
|
|
POSTGRES_DB: $CI_ENVIRONMENT_SLUG
|
|
|
|
production:
|
|
stage: production
|
|
script:
|
|
- install_dependencies
|
|
- deploy
|
|
environment:
|
|
name: production
|
|
url: https://$CI_PROJECT_PATH_SLUG.$KUBE_INGRESS_BASE_DOMAIN
|
|
rules:
|
|
- if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH
|
|
```
|
|
|
|
Content of `.gitlab-ci.yml`:
|
|
|
|
```yaml
|
|
include: 'https://company.com/autodevops-template.yml'
|
|
|
|
image: alpine:latest
|
|
|
|
variables:
|
|
POSTGRES_USER: root
|
|
POSTGRES_PASSWORD: secure_password
|
|
|
|
stages:
|
|
- build
|
|
- test
|
|
- production
|
|
|
|
production:
|
|
environment:
|
|
url: https://domain.com
|
|
```
|
|
|
|
The `POSTGRES_USER` and `POSTGRES_PASSWORD` variables
|
|
and the `environment:url` of the `production` job defined in the `.gitlab-ci.yml` file
|
|
override the values defined in the `autodevops-template.yml` file. The other keywords
|
|
do not change. This method is called *merging*.
|
|
|
|
## Override included configuration arrays
|
|
|
|
You can use merging to extend and override configuration in an included template, but
|
|
you cannot add or modify individual items in an array. For example, to add
|
|
an additional `notify_owner` command to the extended `production` job's `script` array:
|
|
|
|
Content of `autodevops-template.yml`:
|
|
|
|
```yaml
|
|
production:
|
|
stage: production
|
|
script:
|
|
- install_dependencies
|
|
- deploy
|
|
```
|
|
|
|
Content of `.gitlab-ci.yml`:
|
|
|
|
```yaml
|
|
include: 'autodevops-template.yml'
|
|
|
|
stages:
|
|
- production
|
|
|
|
production:
|
|
script:
|
|
- install_dependencies
|
|
- deploy
|
|
- notify_owner
|
|
```
|
|
|
|
If `install_dependencies` and `deploy` are not repeated in
|
|
the `.gitlab-ci.yml` file, the `production` job would have only `notify_owner` in the script.
|
|
|
|
## Use nested includes
|
|
|
|
You can nest `include` sections in configuration files that are then included
|
|
in another configuration. For example, for `include` keywords nested three deep:
|
|
|
|
Content of `.gitlab-ci.yml`:
|
|
|
|
```yaml
|
|
include:
|
|
- local: /.gitlab-ci/another-config.yml
|
|
```
|
|
|
|
Content of `/.gitlab-ci/another-config.yml`:
|
|
|
|
```yaml
|
|
include:
|
|
- local: /.gitlab-ci/config-defaults.yml
|
|
```
|
|
|
|
Content of `/.gitlab-ci/config-defaults.yml`:
|
|
|
|
```yaml
|
|
default:
|
|
after_script:
|
|
- echo "Job complete."
|
|
```
|
|
|
|
### Use nested includes with duplicate `includes` entries
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/28987) in GitLab 14.8
|
|
|
|
Nested includes can include the same configuration file. The duplicate configuration
|
|
file is included multiple times, but the effect is the same as if it was only
|
|
included once.
|
|
|
|
For example, with the following nested includes, where `defaults.gitlab-ci.yml`
|
|
is included multiple times:
|
|
|
|
- Contents of the `.gitlab-ci.yml` file:
|
|
|
|
```yaml
|
|
include:
|
|
- template: defaults.gitlab-ci.yml
|
|
- local: unit-tests.gitlab-ci.yml
|
|
- local: smoke-tests.gitlab-ci.yml
|
|
```
|
|
|
|
- Contents of the `defaults.gitlab-ci.yml` file:
|
|
|
|
```yaml
|
|
default:
|
|
before_script: default-before-script.sh
|
|
retry: 2
|
|
```
|
|
|
|
- Contents of the `unit-tests.gitlab-ci.yml` file:
|
|
|
|
```yaml
|
|
include:
|
|
- template: defaults.gitlab-ci.yml
|
|
|
|
unit-test-job:
|
|
script: unit-test.sh
|
|
retry: 0
|
|
```
|
|
|
|
- Contents of the `smoke-tests.gitlab-ci.yml` file:
|
|
|
|
```yaml
|
|
include:
|
|
- template: defaults.gitlab-ci.yml
|
|
|
|
smoke-test-job:
|
|
script: smoke-test.sh
|
|
```
|
|
|
|
The final configuration would be:
|
|
|
|
```yaml
|
|
unit-test-job:
|
|
before_script: default-before-script.sh
|
|
script: unit-test.sh
|
|
retry: 0
|
|
|
|
smoke-test-job:
|
|
before_script: default-before-script.sh
|
|
script: smoke-test.sh
|
|
retry: 2
|
|
```
|
|
|
|
## Use variables with `include`
|
|
|
|
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/284883) in GitLab 13.8.
|
|
> - [Feature flag removed](https://gitlab.com/gitlab-org/gitlab/-/issues/294294) in GitLab 13.9.
|
|
> - [Support for project, group, and instance variables added](https://gitlab.com/gitlab-org/gitlab/-/issues/219065) in GitLab 14.2.
|
|
> - [Support for pipeline variables added](https://gitlab.com/gitlab-org/gitlab/-/issues/337633) in GitLab 14.5.
|
|
|
|
In `include` sections in your `.gitlab-ci.yml` file, you can use:
|
|
|
|
- [Project variables](../variables/index.md#add-a-cicd-variable-to-a-project).
|
|
- [Group variables](../variables/index.md#add-a-cicd-variable-to-a-group).
|
|
- [Instance variables](../variables/index.md#add-a-cicd-variable-to-an-instance).
|
|
- Project [predefined variables](../variables/predefined_variables.md).
|
|
- In GitLab 14.2 and later, the `$CI_COMMIT_REF_NAME` [predefined variable](../variables/predefined_variables.md).
|
|
|
|
When used in `include`, the `CI_COMMIT_REF_NAME` variable returns the full
|
|
ref path, like `refs/heads/branch-name`. In `include:rules`, you might need to use
|
|
`if: $CI_COMMIT_REF_NAME =~ /main/` (not `== main`). This behavior is resolved in GitLab 14.5.
|
|
|
|
In GitLab 14.5 and later, you can also use:
|
|
|
|
- [Trigger variables](../triggers/index.md#pass-cicd-variables-in-the-api-call).
|
|
- [Scheduled pipeline variables](../pipelines/schedules.md#add-a-pipeline-schedule).
|
|
- [Manual pipeline run variables](../variables/index.md#override-a-variable-when-running-a-pipeline-manually).
|
|
- Pipeline [predefined variables](../variables/predefined_variables.md).
|
|
|
|
YAML files are parsed before the pipeline is created, so the following pipeline predefined variables
|
|
are **not** available:
|
|
|
|
- `CI_PIPELINE_ID`
|
|
- `CI_PIPELINE_URL`
|
|
- `CI_PIPELINE_IID`
|
|
- `CI_PIPELINE_CREATED_AT`
|
|
|
|
For example:
|
|
|
|
```yaml
|
|
include:
|
|
project: '$CI_PROJECT_PATH'
|
|
file: '.compliance-gitlab-ci.yml'
|
|
```
|
|
|
|
You cannot use variables defined in jobs, or in a global [`variables`](../yaml/index.md#variables)
|
|
section which defines the default variables for all jobs. Includes are evaluated before jobs,
|
|
so these variables cannot be used with `include`.
|
|
|
|
For an example of how you can include predefined variables, and the variables' impact on CI/CD jobs,
|
|
see this [CI/CD variable demo](https://youtu.be/4XR8gw3Pkos).
|
|
|
|
## Use `rules` with `include`
|
|
|
|
> - Introduced in GitLab 14.2 [with a flag](../../administration/feature_flags.md) named `ci_include_rules`. Disabled by default.
|
|
> - [Enabled on GitLab.com](https://gitlab.com/gitlab-org/gitlab/-/issues/337507) in GitLab 14.3.
|
|
> - [Enabled on self-managed](https://gitlab.com/gitlab-org/gitlab/-/issues/337507) GitLab 14.3.
|
|
> - [Feature flag `ci_include_rules` removed](https://gitlab.com/gitlab-org/gitlab/-/issues/337507) in GitLab 14.4.
|
|
> - [Generally available](https://gitlab.com/gitlab-org/gitlab/-/issues/337507) in GitLab 14.4.
|
|
> - [Support for `exists` keyword added](https://gitlab.com/gitlab-org/gitlab/-/issues/341511) in GitLab 14.5.
|
|
|
|
You can use [`rules`](index.md#rules) with `include` to conditionally include other configuration files.
|
|
|
|
You can only use the following rules with `include` (and only with [certain variables](#use-variables-with-include)):
|
|
|
|
- [`if` rules](index.md#rulesif). For example:
|
|
|
|
```yaml
|
|
include:
|
|
- local: builds.yml
|
|
rules:
|
|
- if: $INCLUDE_BUILDS == "true"
|
|
- local: deploys.yml
|
|
rules:
|
|
- if: $CI_COMMIT_BRANCH == "main"
|
|
|
|
test:
|
|
stage: test
|
|
script: exit 0
|
|
```
|
|
|
|
- [`exists` rules](index.md#rulesexists). For example:
|
|
|
|
```yaml
|
|
include:
|
|
- local: builds.yml
|
|
rules:
|
|
- exists:
|
|
- file.md
|
|
|
|
test:
|
|
stage: test
|
|
script: exit 0
|
|
```
|
|
|
|
`rules` keyword `changes` is not supported.
|
|
|
|
You cannot use [`needs:`](index.md#needs) to create a job dependency that points to
|
|
a job added with `include:local:rules`. When the configuration is checked for validity,
|
|
GitLab returns `undefined need: <job-name>`. An [issue exists](https://gitlab.com/gitlab-org/gitlab/-/issues/345377)
|
|
to improve this behavior.
|
|
|
|
## Use `include:local` with wildcard file paths
|
|
|
|
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/25921) in GitLab 13.11.
|
|
> - [Feature flag removed](https://gitlab.com/gitlab-org/gitlab/-/issues/327315) in GitLab 14.2.
|
|
|
|
You can use wildcard paths (`*` and `**`) with `include:local`.
|
|
|
|
Example:
|
|
|
|
```yaml
|
|
include: 'configs/*.yml'
|
|
```
|
|
|
|
When the pipeline runs, GitLab:
|
|
|
|
- Adds all `.yml` files in the `configs` directory into the pipeline configuration.
|
|
- Does not add `.yml` files in subfolders of the `configs` directory. To allow this,
|
|
add the following configuration:
|
|
|
|
```yaml
|
|
# This matches all `.yml` files in `configs` and any subfolder in it.
|
|
include: 'configs/**.yml'
|
|
|
|
# This matches all `.yml` files only in subfolders of `configs`.
|
|
include: 'configs/**/*.yml'
|
|
```
|
