# CI/CD variables
|
|
|
|
Use CI/CD variables to set up the Auto DevOps domain, provide a custom
|
|
Helm chart, or scale your application.
|
|
|
|
## Build and deployment variables
|
|
|
|
Use these variables to customize and deploy your build.
|
|
|
|
| **CI/CD variable** | **Description** |
|
|
|-----------------------------------------|------------------------------------|
|
|
| `ADDITIONAL_HOSTS` | Fully qualified domain names specified as a comma-separated list that are added to the Ingress hosts. |
|
|
| `<ENVIRONMENT>_ADDITIONAL_HOSTS` | For a specific environment, the fully qualified domain names specified as a comma-separated list that are added to the Ingress hosts. This takes precedence over `ADDITIONAL_HOSTS`. |
|
|
| `AUTO_BUILD_IMAGE_VERSION` | Customize the image version used for the `build` job. See [list of versions](https://gitlab.com/gitlab-org/cluster-integration/auto-build-image/-/releases). |
|
|
| `AUTO_DEPLOY_IMAGE_VERSION` | Customize the image version used for Kubernetes deployment jobs. See [list of versions](https://gitlab.com/gitlab-org/cluster-integration/auto-deploy-image/-/releases). |
|
|
| `AUTO_DEVOPS_ATOMIC_RELEASE` | As of GitLab 13.0, Auto DevOps uses [`--atomic`](https://v2.helm.sh/docs/helm/#options-43) for Helm deployments by default. Set this variable to `false` to disable the use of `--atomic` |
|
|
| `AUTO_DEVOPS_BUILD_IMAGE_CNB_ENABLED` | Set to `false` to use Herokuish instead of Cloud Native Buildpacks with Auto Build. [More details](stages.md#auto-build-using-cloud-native-buildpacks). |
|

|
|
| `HELM_UPGRADE_EXTRA_ARGS` | Allows extra options in `helm upgrade` commands when deploying the application. Using quotes doesn't prevent word splitting. |
|
|
| `INCREMENTAL_ROLLOUT_MODE` | If present, can be used to enable an [incremental rollout](#incremental-rollout-to-production) of your application for the production environment. Set to `manual` for manual deployment jobs or `timed` for automatic rollout deployments with a 5 minute delay each one. |
|
|
| `K8S_SECRET_*` | Any variable prefixed with [`K8S_SECRET_`](#configure-application-secret-variables) is made available by Auto DevOps as environment variables to the deployed application. |
|
|
| `KUBE_CONTEXT` | From GitLab 14.5, can be used to select a context to use from `KUBECONFIG`. When `KUBE_CONTEXT` is blank, the default context in `KUBECONFIG` (if any) is used. A context must be selected when used [with the agent for Kubernetes](../../user/clusters/agent/ci_cd_workflow.md). |
|
|
| `KUBE_INGRESS_BASE_DOMAIN` | Can be used to set a domain per cluster. See [cluster domains](../../user/project/clusters/gitlab_managed_clusters.md#base-domain) for more information. |
|
|
| `KUBE_NAMESPACE` | The namespace used for deployments. When using certificate-based clusters, [this value should not be overwritten directly](../../user/project/clusters/deploy_to_cluster.md#custom-namespace). |
|
|
| `KUBECONFIG` | The kubeconfig to use for deployments. User-provided values take priority over GitLab-provided values. |
|
|
| `PRODUCTION_REPLICAS` | Number of replicas to deploy in the production environment. Takes precedence over `REPLICAS` and defaults to 1. For zero downtime upgrades, set to 2 or greater. |
|
|
| `REPLICAS` | Number of replicas to deploy. Defaults to 1. Change this variable instead of [modifying](customize.md#customize-helm-chart-values) `replicaCount`. |
|
|
| `ROLLOUT_RESOURCE_TYPE` | Allows specification of the resource type being deployed when using a custom Helm chart. Default value is `deployment`. |
|
|
| `ROLLOUT_STATUS_DISABLED` | Used to disable rollout status check because it does not support all resource types, for example, `cronjob`. |
|
|
| `STAGING_ENABLED` | Used to define a [deploy policy for staging and production environments](#deploy-policy-for-staging-and-production-environments). |
|
|
| `TRACE` | Set to any value to make Helm commands produce verbose output. You can use this setting to help diagnose Auto DevOps deployment problems. |
|
|
|
|
## Database variables
|
|
|
|
WARNING:
|
|
The default value of `true` for `POSTGRES_ENABLED` was [deprecated](https://gitlab.com/gitlab-org/gitlab/-/issues/387766)
|
|
in GitLab 15.8. In [GitLab 16.0](https://gitlab.com/gitlab-org/gitlab/-/issues/343988), the default value will change to `false`.
|
|
|
|
Use these variables to integrate CI/CD with PostgreSQL databases.
|
|
|
|
| **CI/CD variable** | **Description** |
|
|
|-----------------------------------------|------------------------------------|
|
|
| `DB_INITIALIZE` | Used to specify the command to run to initialize the application's PostgreSQL database. Runs inside the application pod. |
|
|
| `DB_MIGRATE` | Used to specify the command to run to migrate the application's PostgreSQL database. Runs inside the application pod. |
|
|
| `POSTGRES_ENABLED` | Whether PostgreSQL is enabled. Defaults to `true` until GitLab 16.0, when the default will change to `false`. Set to `false` to disable the automatic deployment of PostgreSQL. |
|
|
| `POSTGRES_USER` | The PostgreSQL user. Defaults to `user`. Set it to use a custom username. |
|
|
| `POSTGRES_PASSWORD` | The PostgreSQL password. Defaults to `testing-password`. Set it to use a custom password. |
|
|
| `POSTGRES_DB` | The PostgreSQL database name. Defaults to the value of [`$CI_ENVIRONMENT_SLUG`](../../ci/variables/index.md#predefined-cicd-variables). Set it to use a custom database name. |
|
|
| `POSTGRES_VERSION` | Tag for the [`postgres` Docker image](https://hub.docker.com/_/postgres) to use. Defaults to `9.6.16` for tests and deployments as of GitLab 13.0 (previously `9.6.2`). If `AUTO_DEVOPS_POSTGRES_CHANNEL` is set to `1`, deployments uses the default version `9.6.2`. |
|
|
| `POSTGRES_HELM_UPGRADE_VALUES_FILE` | In GitLab 13.8 and later, and when using [auto-deploy-image v2](upgrading_auto_deploy_dependencies.md), this variable allows the `helm upgrade` values file for PostgreSQL to be overridden. Defaults to `.gitlab/auto-deploy-postgres-values.yaml`. |
|
|
| `POSTGRES_HELM_UPGRADE_EXTRA_ARGS` | In GitLab 13.8 and later, and when using [auto-deploy-image v2](upgrading_auto_deploy_dependencies.md), this variable allows extra PostgreSQL options in `helm upgrade` commands when deploying the application. Using quotes doesn't prevent word splitting. |
|
|
| `POSTGRES_CHART_REPOSITORY` | Helm Chart repository used to search for PostgreSQL chart. Defaults to `https://raw.githubusercontent.com/bitnami/charts/eb5f9a9513d987b519f0ecd732e7031241c50328/bitnami`. |
|

## Configure application secret variables
|
|
|
|
Some deployed applications require access to secret variables.
|
|
Auto DevOps detects CI/CD variables starting with `K8S_SECRET_`,
|
|
and makes them available to the deployed application as
|
|
environment variables.
|
|
|
|
Prerequisite:
|
|
|
|
- The variable value must be a single line.
|
|
|
|
To configure secret variables:
|
|
|
|
1. On the top bar, select **Main menu > Projects** and find your project.
|
|
1. On the left sidebar, select **Settings > CI/CD**.
|
|
1. Expand **Variables**.
|
|
1. Create a CI/CD variable with the prefix `K8S_SECRET_`. For example, you
|
|
can create a variable called `K8S_SECRET_RAILS_MASTER_KEY`.
|
|
1. Run an Auto DevOps pipeline, either by manually creating a new
|
|
pipeline or by pushing a code change to GitLab.
|
|
|
|
### Kubernetes secrets
|
|
|
|
Auto DevOps pipelines use your application secret variables to
|
|
populate a Kubernetes secret. This secret is unique per environment.
|
|
When deploying your application, the secret is loaded as environment
|
|
variables in the container running the application. For example, if
|
|
you create a secret called `K8S_SECRET_RAILS_MASTER_KEY`, your
|
|
Kubernetes secret might look like:
|
|
|
|
```shell
|
|
$ kubectl get secret production-secret -n minimal-ruby-app-54 -o yaml
|
|
|
|
apiVersion: v1
|
|
data:
|
|
RAILS_MASTER_KEY: MTIzNC10ZXN0
|
|
kind: Secret
|
|
metadata:
|
|
creationTimestamp: 2018-12-20T01:48:26Z
|
|
name: production-secret
|
|
namespace: minimal-ruby-app-54
|
|
resourceVersion: "429422"
|
|
selfLink: /api/v1/namespaces/minimal-ruby-app-54/secrets/production-secret
|
|
uid: 57ac2bfd-03f9-11e9-b812-42010a9400e4
|
|
type: Opaque
|
|
```
|
|
|
|
## Update application secrets
|
|
|
|
Environment variables are generally immutable in a Kubernetes pod.
|
|
If you update an application secret and then manually
|
|
create a new pipeline, running applications do not receive the
|
|
updated secret.
|
|
|
|
To update application secrets, either:
|
|
|
|
- Push a code update to GitLab to force the Kubernetes deployment to recreate pods.
|
|
- Manually delete running pods to cause Kubernetes to create new pods with updated
|
|
secrets.
|
|
|
|
Variables with multi-line values are not supported due to
|
|
limitations with the Auto DevOps scripting environment.
|
|
|
|
## Configure replica variables
|
|
|
|
Add replica variables when you want to scale your deployments:
|
|
|
|
1. Add a replica variable as a [project CI/CD variable](../../ci/variables/index.md#for-a-project).
|
|
1. To scale your application, redeploy it.
|
|
|
|
WARNING:
|
|
Do not scale your application using Kubernetes directly. Helm might not detect the change,
|
|
and subsequent deployments with Auto DevOps can undo your changes.
|
|
|
|
### Custom replica variables
|
|
|
|
You can create custom replica variables with the format `<TRACK>_<ENV>_REPLICAS`:
|
|
|
|
- `<TRACK>` is the all-caps value of the `track`
|
|
[Kubernetes label](https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/)
|
|
set in the Helm Chart app definition. If `track` is not set, omit `<TRACK>` from the custom variable.
|
|
- `<ENV>` is the all-caps environment name of the deploy job set in
|
|
`.gitlab-ci.yml`.
|
|
|
|
For example, if the environment is `qa` and the track is
|
|
`foo`, create an environment variable called `FOO_QA_REPLICAS`:
|
|
|
|
```yaml
|
|
QA testing:
|
|
stage: deploy
|
|
environment:
|
|
name: qa
|
|
script:
|
|
- deploy foo
|
|
```
|
|
|
|
The track `foo` must be defined in the application's Helm chart.
|
|
For example:
|
|
|
|
```yaml
|
|
replicaCount: 1
|
|
image:
|
|
repository: gitlab.example.com/group/project
|
|
tag: stable
|
|
pullPolicy: Always
|
|
secrets:
|
|
- name: gitlab-registry
|
|
application:
|
|
track: foo
|
|
tier: web
|
|
service:
|
|
enabled: true
|
|
name: web
|
|
type: ClusterIP
|
|
url: http://my.host.com/
|
|
externalPort: 5000
|
|
internalPort: 5000
|
|
```
|
|
|
|
## Deploy policy for staging and production environments
|
|
|
|
Auto DevOps typically uses continuous deployment, and pushes
|
|
automatically to the `production` environment whenever a new pipeline
|
|
runs on the default branch. To deploy to production manually, you can
|
|
use the `STAGING_ENABLED` CI/CD variable.
|
|
|
|
If you set `STAGING_ENABLED`, GitLab automatically deploys the
|
|
application to a `staging` environment. When you're ready to deploy to
|
|
production, GitLab creates a `production_manual` job.
|
|
|
|
You can also enable manual deployment in your [project settings](requirements.md#auto-devops-deployment-strategy).
|
|
|
|
## Deploy policy for canary environments **(PREMIUM)**
|
|
|
|
You can use a [canary environment](../../user/project/canary_deployments.md) before
|
|
deploying any changes to production.
|
|
|
|
If you set `CANARY_ENABLED`, GitLab creates two [manual jobs](../../ci/pipelines/index.md#add-manual-interaction-to-your-pipeline):
|
|
|
|
- `canary` - Deploys the application to the canary environment.
|
|
- `production_manual` - Deploys the application to production.
|
|
|
|
## Incremental rollout to production **(PREMIUM)**
|
|
|
|
Use an incremental rollout to continuously deploy your application,
|
|
starting with only a few pods. You can increase the number of pods
|
|
manually.
|
|
|
|
You can enable manual deployment in your [project settings](requirements.md#auto-devops-deployment-strategy),
|
|
or by setting `INCREMENTAL_ROLLOUT_MODE` to `manual`.
|
|
|
|
If you set `INCREMENTAL_ROLLOUT_MODE` to `manual`, GitLab creates four
|
|
manual jobs:
|
|
|
|
1. `rollout 10%`
|
|
1. `rollout 25%`
|
|
1. `rollout 50%`

1. `rollout 100%`
|
|
|
|
The percentage is based on the `REPLICAS` CI/CD variable, and defines the number of
|
|
pods used for deployment. For example, if the value is `10` and you run the
|
|
`10%` rollout job, your application is deployed to only one pod.
|
|
|
|
You can run the rollout jobs in any order. To scale down, rerun a
|
|
lower percentage job.
|
|
|
|
After you run the `rollout 100%` job, you cannot scale down, and must
|
|
[roll back your deployment](../../ci/environments/index.md#retry-or-roll-back-a-deployment).

|
Without `INCREMENTAL_ROLLOUT_MODE` and with `STAGING_ENABLED`:
|
|
|
|
![Staging enabled](img/staging_enabled.png)
|
|
|
|
With `INCREMENTAL_ROLLOUT_MODE` set to `manual` and without `STAGING_ENABLED`:
|
|
|
|

|
|
With `INCREMENTAL_ROLLOUT_MODE` set to `manual` and with `STAGING_ENABLED`:

|
## Timed incremental rollout to production **(PREMIUM)**
|
|
|
|
Use a timed incremental rollout to continuously deploy your application, starting with
|
|
only a few pods.
|
|
|
|
You can enable timed incremental deployment in your [project settings](requirements.md#auto-devops-deployment-strategy),
|
|
or by setting the `INCREMENTAL_ROLLOUT_MODE` CI/CD variable to `timed`.
|
|
|
|
If you set `INCREMENTAL_ROLLOUT_MODE` to `timed`, GitLab creates four jobs:
|
|
|
|
1. `timed rollout 10%`
|
|
1. `timed rollout 25%`
|
|
1. `timed rollout 50%`
|
|
1. `timed rollout 100%`
|
|
|
|
There is a five-minute delay between jobs.
