--- stage: Configure group: Configure info: To determine the technical writer assigned to the Stage/Group associated with this page, see https://about.gitlab.com/handbook/engineering/ux/technical-writing/#assignments --- # Customizing Auto DevOps **(FREE)** While [Auto DevOps](index.md) provides great defaults to get you started, you can customize almost everything to fit your needs. Auto DevOps offers everything from custom [buildpacks](#custom-buildpacks), to [Dockerfiles](#custom-dockerfile), and [Helm charts](#custom-helm-chart). You can even copy the complete [CI/CD configuration](#customizing-gitlab-ciyml) into your project to enable staging and canary deployments, [manage Auto DevOps with GitLab APIs](customize.md#extend-auto-devops-with-the-api), and more. ## Custom buildpacks If the automatic buildpack detection fails for your project, or if you need more control over your build, you can customize the buildpacks used for the build. ### Custom buildpacks with Cloud Native Buildpacks > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/28165) in GitLab 12.10. Specify either: - The CI/CD variable `BUILDPACK_URL` according to [`pack`'s specifications](https://buildpacks.io/docs/app-developer-guide/specific-buildpacks/). - A [`project.toml` project descriptor](https://buildpacks.io/docs/app-developer-guide/using-project-descriptor/) with the buildpacks you would like to include. ### Custom buildpacks with Herokuish Specify either: - The CI/CD variable `BUILDPACK_URL`. - A `.buildpacks` file at the root of your project, containing one buildpack URL per line. The buildpack URL can point to either a Git repository URL or a tarball URL. For Git repositories, you can point to a specific Git reference (such as commit SHA, tag name, or branch name) by appending `#` to the Git repository URL. For example: - The tag `v142`: `https://github.com/heroku/heroku-buildpack-ruby.git#v142`. - The branch `mybranch`: `https://github.com/heroku/heroku-buildpack-ruby.git#mybranch`. - The commit SHA `f97d8a8ab49`: `https://github.com/heroku/heroku-buildpack-ruby.git#f97d8a8ab49`. ### Multiple buildpacks Using multiple buildpacks is not fully supported by Auto DevOps, because Auto Test can't use the `.buildpacks` file. The buildpack [heroku-buildpack-multi](https://github.com/heroku/heroku-buildpack-multi/), used in the backend to parse the `.buildpacks` file, does not provide the necessary commands `bin/test-compile` and `bin/test`. If your goal is to use only a single custom buildpack, you should provide the project CI/CD variable `BUILDPACK_URL` instead. ## Custom `Dockerfile` > Support for `DOCKERFILE_PATH` was [introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/35662) in GitLab 13.2 If your project has a `Dockerfile` in the root of the project repository, Auto DevOps builds a Docker image based on the Dockerfile, rather than using buildpacks. This can be much faster and result in smaller images, especially if your Dockerfile is based on [Alpine](https://hub.docker.com/_/alpine/). If you set the `DOCKERFILE_PATH` CI/CD variable, Auto Build looks for a Dockerfile there instead. ## Passing arguments to `docker build` Arguments can be passed to the `docker build` command using the `AUTO_DEVOPS_BUILD_IMAGE_EXTRA_ARGS` project CI/CD variable. For example, to build a Docker image based on based on the `ruby:alpine` instead of the default `ruby:latest`: 1. Set `AUTO_DEVOPS_BUILD_IMAGE_EXTRA_ARGS` to `--build-arg=RUBY_VERSION=alpine`. 1. Add the following to a custom `Dockerfile`: ```dockerfile ARG RUBY_VERSION=latest FROM ruby:$RUBY_VERSION # ... put your stuff here ``` Use Base64 encoding if you need to pass complex values, such as newlines and spaces. Left unencoded, complex values like these can cause escaping issues due to how Auto DevOps uses the arguments. WARNING: Avoid passing secrets as Docker build arguments if possible, as they may be persisted in your image. See [this discussion of best practices with secrets](https://github.com/moby/moby/issues/13490) for details. ## Extend Auto DevOps with the API You can extend and manage your Auto DevOps configuration with GitLab APIs: - [Settings that can be accessed with API calls](../../api/settings.md#list-of-settings-that-can-be-accessed-via-api-calls), which include `auto_devops_enabled`, to enable Auto DevOps on projects by default. - [Creating a new project](../../api/projects.md#create-project). - [Editing groups](../../api/groups.md#update-group). - [Editing projects](../../api/projects.md#edit-project). ## Forward CI/CD variables to the build environment > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/25514) in GitLab 12.3, but available in versions 11.9 and above. CI/CD variables can be forwarded into the build environment using the `AUTO_DEVOPS_BUILD_IMAGE_FORWARDED_CI_VARIABLES` CI/CD variable. The forwarded variables should be specified by name in a comma-separated list. For example, to forward the variables `CI_COMMIT_SHA` and `CI_ENVIRONMENT_NAME`, set `AUTO_DEVOPS_BUILD_IMAGE_FORWARDED_CI_VARIABLES` to `CI_COMMIT_SHA,CI_ENVIRONMENT_NAME`. - When using Buildpacks, the forwarded variables are available automatically as environment variables. - When using a `Dockerfile`, the following additional steps are required: 1. Activate the experimental `Dockerfile` syntax by adding the following code to the top of the file: ```dockerfile # syntax = docker/dockerfile:experimental ``` 1. To make secrets available in any `RUN $COMMAND` in the `Dockerfile`, mount the secret file and source it prior to running `$COMMAND`: ```dockerfile RUN --mount=type=secret,id=auto-devops-build-secrets . /run/secrets/auto-devops-build-secrets && $COMMAND ``` When `AUTO_DEVOPS_BUILD_IMAGE_FORWARDED_CI_VARIABLES` is set, Auto DevOps enables the experimental [Docker BuildKit](https://docs.docker.com/develop/develop-images/build_enhancements/) feature to use the `--secret` flag. ## Custom Helm Chart Auto DevOps uses [Helm](https://helm.sh/) to deploy your application to Kubernetes. You can override the Helm chart used by bundling up a chart into your project repository or by specifying a project CI/CD variable: - **Bundled chart** - If your project has a `./chart` directory with a `Chart.yaml` file in it, Auto DevOps detects the chart and uses it instead of the [default chart](https://gitlab.com/gitlab-org/cluster-integration/auto-deploy-image/-/tree/master/assets/auto-deploy-app), enabling you to control exactly how your application is deployed. - **Project variable** - Create a [project CI/CD variable](../../ci/variables/index.md) `AUTO_DEVOPS_CHART` with the URL of a custom chart to use, or create two project variables: `AUTO_DEVOPS_CHART_REPOSITORY` with the URL of a custom chart repository, and `AUTO_DEVOPS_CHART` with the path to the chart. ## Customize values for Helm Chart > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/30628) in GitLab 12.6, `.gitlab/auto-deploy-values.yaml` is used by default for Helm upgrades. You can override the default values in the `values.yaml` file in the [default Helm chart](https://gitlab.com/gitlab-org/cluster-integration/auto-deploy-image/-/tree/master/assets/auto-deploy-app) by either: - Adding a file named `.gitlab/auto-deploy-values.yaml` to your repository, which is automatically used, if found. - Adding a file with a different name or path to the repository, and setting the `HELM_UPGRADE_VALUES_FILE` [CI/CD variable](#cicd-variables) with the path and name. NOTE: For GitLab 12.5 and earlier, use the `HELM_UPGRADE_EXTRA_ARGS` variable to override the default chart values by setting `HELM_UPGRADE_EXTRA_ARGS` to `--values `. ## Customize the `helm upgrade` command You can customize the `helm upgrade` command used in the [auto-deploy-image](https://gitlab.com/gitlab-org/cluster-integration/auto-deploy-image) by passing options to the command with the `HELM_UPGRADE_EXTRA_ARGS` CI/CD variable. For example, set the value of `HELM_UPGRADE_EXTRA_ARGS` to `--no-hooks` to disable pre-upgrade and post-upgrade hooks when the command is executed. See [the official documentation](https://helm.sh/docs/helm/helm_upgrade/) for the full list of options. ## Custom Helm chart per environment You can specify the use of a custom Helm chart per environment by scoping the CI/CD variable to the desired environment. See [Limit environment scope of CI/CD variables](../../ci/variables/index.md#limit-the-environment-scope-of-a-cicd-variable). ## Customizing `.gitlab-ci.yml` Auto DevOps is completely customizable because the [Auto DevOps template](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/ci/templates/Auto-DevOps.gitlab-ci.yml) is just an implementation of a [`.gitlab-ci.yml`](../../ci/yaml/index.md) file, and uses only features available to any implementation of `.gitlab-ci.yml`. To modify the CI/CD pipeline used by Auto DevOps, [`include` the template](../../ci/yaml/index.md#includetemplate), and customize it as needed by adding a `.gitlab-ci.yml` file to the root of your repository containing the following: ```yaml include: - template: Auto-DevOps.gitlab-ci.yml ``` Add your changes, and your additions are merged with the [Auto DevOps template](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/ci/templates/Auto-DevOps.gitlab-ci.yml) using the behavior described for [`include`](../../ci/yaml/index.md#include). If you need to specifically remove a part of the file, you can also copy and paste the contents of the [Auto DevOps template](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/ci/templates/Auto-DevOps.gitlab-ci.yml) into your project and edit it as needed. ## Use multiple Kubernetes clusters See [Multiple Kubernetes clusters for Auto DevOps](multiple_clusters_auto_devops.md). ## Customizing the Kubernetes namespace > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/27630) in GitLab 12.6. For clusters not managed by GitLab, you can customize the namespace in `.gitlab-ci.yml` by specifying [`environment:kubernetes:namespace`](../../ci/environments/index.md#configure-kubernetes-deployments). For example, the following configuration overrides the namespace used for `production` deployments: ```yaml include: - template: Auto-DevOps.gitlab-ci.yml production: environment: kubernetes: namespace: production ``` When deploying to a custom namespace with Auto DevOps, the service account provided with the cluster needs at least the `edit` role within the namespace. - If the service account can create namespaces, then the namespace can be created on-demand. - Otherwise, the namespace must exist prior to deployment. ## Using components of Auto DevOps If you only require a subset of the features offered by Auto DevOps, you can include individual Auto DevOps jobs into your own `.gitlab-ci.yml`. Each component job relies on a stage that should be defined in the `.gitlab-ci.yml` that includes the template. For example, to make use of [Auto Build](stages.md#auto-build), you can add the following to your `.gitlab-ci.yml`: ```yaml stages: - build include: - template: Jobs/Build.gitlab-ci.yml ``` See the [Auto DevOps template](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/ci/templates/Auto-DevOps.gitlab-ci.yml) for information on available jobs. WARNING: Auto DevOps templates using the [`only`](../../ci/yaml/index.md#only--except) or [`except`](../../ci/yaml/index.md#only--except) syntax have switched to the [`rules`](../../ci/yaml/index.md#rules) syntax, starting in [GitLab 13.0](https://gitlab.com/gitlab-org/gitlab/-/issues/213336). If your `.gitlab-ci.yml` extends these Auto DevOps templates and override the `only` or `except` keywords, you must migrate your templates to use the [`rules`](../../ci/yaml/index.md#rules) syntax after the base template is migrated to use the `rules` syntax. For users who cannot migrate just yet, you can alternatively pin your templates to the [GitLab 12.10 based templates](https://gitlab.com/gitlab-org/auto-devops-v12-10). ## Use images hosted in a local Docker registry You can configure many Auto DevOps jobs to run in an [offline environment](../../user/application_security/offline_deployments/index.md): 1. Copy the required Auto DevOps Docker images from Docker Hub and `registry.gitlab.com` to their local GitLab container registry. 1. After the images are hosted and available in a local registry, edit `.gitlab-ci.yml` to point to the locally-hosted images. For example: ```yaml include: - template: Auto-DevOps.gitlab-ci.yml variables: REGISTRY_URL: "registry.gitlab.example" build: image: "$REGISTRY_URL/docker/auto-build-image:v0.6.0" services: - name: "$REGISTRY_URL/greg/docker/docker:20.10.6-dind" command: ['--tls=false', '--host=tcp://0.0.0.0:2375'] ``` ## PostgreSQL database support To support applications requiring a database, [PostgreSQL](https://www.postgresql.org/) is provisioned by default. The credentials to access the database are preconfigured, but can be customized by setting the associated [CI/CD variables](#cicd-variables). You can use these credentials to define a `DATABASE_URL`: ```yaml postgres://user:password@postgres-host:postgres-port/postgres-database ``` ### Upgrading PostgresSQL WARNING: The CI/CD variable `AUTO_DEVOPS_POSTGRES_CHANNEL` that controls default provisioned PostgreSQL was changed to `2` in [GitLab 13.0](https://gitlab.com/gitlab-org/gitlab/-/issues/210499). To keep using the old PostgreSQL, set the `AUTO_DEVOPS_POSTGRES_CHANNEL` variable to `1`. The version of the chart used to provision PostgreSQL: - Is 8.2.1 in GitLab 13.0 and later, but can be set back to 0.7.1 if needed. - Can be set to from 0.7.1 to 8.2.1 in GitLab 12.9 and 12.10. - Is 0.7.1 in GitLab 12.8 and earlier. GitLab encourages users to [migrate their database](upgrading_postgresql.md) to the newer PostgreSQL. ### Customize values for PostgreSQL Helm Chart > [Introduced](https://gitlab.com/gitlab-org/cluster-integration/auto-deploy-image/-/issues/113) in auto-deploy-image v2, in GitLab 13.8. To set custom values, do one of the following: - Add a file named `.gitlab/auto-deploy-postgres-values.yaml` to your repository. If found, this file is used automatically. This file is used by default for PostgreSQL Helm upgrades. - Add a file with a different name or path to the repository, and set the `POSTGRES_HELM_UPGRADE_VALUES_FILE` [environment variable](#database) with the path and name. - Set the `POSTGRES_HELM_UPGRADE_EXTRA_ARGS` [environment variable](#database). ### Using external PostgreSQL database providers While Auto DevOps provides out-of-the-box support for a PostgreSQL container for production environments, for some use cases, it may not be sufficiently secure or resilient, and you may want to use an external managed provider (such as AWS Relational Database Service) for PostgreSQL. You must define environment-scoped CI/CD variables for `POSTGRES_ENABLED` and `DATABASE_URL` in your project's CI/CD settings: 1. Disable the built-in PostgreSQL installation for the required environments using environment-scoped [CI/CD variables](../../ci/environments/index.md#scope-environments-with-specs). For this use case, it's likely that only `production` must be added to this list. The built-in PostgreSQL setup for Review Apps and staging is sufficient. ![Auto Metrics](img/disable_postgres.png) 1. Define the `DATABASE_URL` variable as an environment-scoped variable that is available to your application. This should be a URL in the following format: ```yaml postgres://user:password@postgres-host:postgres-port/postgres-database ``` You must ensure that your Kubernetes cluster has network access to wherever PostgreSQL is hosted. ## CI/CD variables The following variables can be used for setting up the Auto DevOps domain, providing a custom Helm chart, or scaling your application. PostgreSQL can also be customized, and you can use a [custom buildpack](#custom-buildpacks). ### Build and deployment The following table lists CI/CD variables related to building and deploying applications. | **CI/CD Variable** | **Description** | |-----------------------------------------|------------------------------------| | `ADDITIONAL_HOSTS` | Fully qualified domain names specified as a comma-separated list that are added to the Ingress hosts. | | `_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). | | `AUTO_DEVOPS_BUILD_IMAGE_CNB_BUILDER` | The builder used when building with Cloud Native Buildpacks. The default builder is `heroku/buildpacks:18`. [More details](stages.md#auto-build-using-cloud-native-buildpacks). | | `AUTO_DEVOPS_BUILD_IMAGE_EXTRA_ARGS` | Extra arguments to be passed to the `docker build` command. Note that using quotes doesn't prevent word splitting.

Defaults to no credentials. Also set `AUTO_DEVOPS_CHART_REPOSITORY_USERNAME`. | | `AUTO_DEVOPS_CHART_REPOSITORY_PASS_CREDENTIALS` | From GitLab 14.2, set to a non-empty value to enable forwarding of the Helm repository credentials to the chart server when the chart artifacts are on a different host than repository. | | `AUTO_DEVOPS_DEPLOY_DEBUG` | From GitLab 13.1, if this variable is present, Helm outputs debug logs. | | `AUTO_DEVOPS_ALLOW_TO_FORCE_DEPLOY_V` | From [auto-deploy-image](https://gitlab.com/gitlab-org/cluster-integration/auto-deploy-image) v1.0.0, if this variable is present, a new major version of chart is forcibly deployed. For more information, see [Ignore warnings and continue deploying](upgrading_auto_deploy_dependencies.md#ignore-warnings-and-continue-deploying). | | `BUILDPACK_URL` | Buildpack's full URL. [Must point to a URL supported by Pack or Herokuish](#custom-buildpacks). | | `CANARY_ENABLED` | From GitLab 11.0, used to define a [deploy policy for canary environments](#deploy-policy-for-canary-environments). | | `CANARY_PRODUCTION_REPLICAS` | Number of canary replicas to deploy for [Canary Deployments](../../user/project/canary_deployments.md) in the production environment. Takes precedence over `CANARY_REPLICAS`. Defaults to 1. | | `CANARY_REPLICAS` | Number of canary replicas to deploy for [Canary Deployments](../../user/project/canary_deployments.md). Defaults to 1. | | `DAST_AUTO_DEPLOY_IMAGE_VERSION` | Customize the image version used for DAST deployments on the default branch. Should usually be the same as `AUTO_DEPLOY_IMAGE_VERSION`. See [list of versions](https://gitlab.com/gitlab-org/cluster-integration/auto-deploy-image/-/releases). | | `DOCKERFILE_PATH` | From GitLab 13.2, allows overriding the [default Dockerfile path for the build stage](#custom-dockerfile) | | `HELM_RELEASE_NAME` | From GitLab 12.1, allows the `helm` release name to be overridden. Can be used to assign unique release names when deploying multiple projects to a single namespace. | | `HELM_UPGRADE_VALUES_FILE` | From GitLab 12.6, allows the `helm upgrade` values file to be overridden. Defaults to `.gitlab/auto-deploy-values.yaml`. | | `HELM_UPGRADE_EXTRA_ARGS` | From GitLab 11.11, allows extra options in `helm upgrade` commands when deploying the application. Note that using quotes doesn't prevent word splitting. | | `INCREMENTAL_ROLLOUT_MODE` | From GitLab 11.4, 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_*` | From GitLab 11.7, any variable prefixed with [`K8S_SECRET_`](#application-secret-variables) is made available by Auto DevOps as environment variables to the deployed application. | | `KUBE_INGRESS_BASE_DOMAIN` | From GitLab 11.8, can be used to set a domain per cluster. See [cluster domains](../../user/project/clusters/gitlab_managed_clusters.md#base-domain) for more information. | | `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. | | `ROLLOUT_RESOURCE_TYPE` | From GitLab 11.9, allows specification of the resource type being deployed when using a custom Helm chart. Default value is `deployment`. | | `ROLLOUT_STATUS_DISABLED` | From GitLab 12.0, used to disable rollout status check because it does not support all resource types, for example, `cronjob`. | | `STAGING_ENABLED` | From GitLab 10.8, used to define a [deploy policy for staging and production environments](#deploy-policy-for-staging-and-production-environments). | NOTE: After you set up your replica variables using a [project CI/CD variable](../../ci/variables/index.md), you can scale your application by redeploying it. WARNING: You should *not* scale your application using Kubernetes directly. This can cause confusion with Helm not detecting the change, and subsequent deploys with Auto DevOps can undo your changes. ### Database The following table lists CI/CD variables related to the database. | **CI/CD Variable** | **Description** | |-----------------------------------------|------------------------------------| | `DB_INITIALIZE` | From GitLab 11.4, used to specify the command to run to initialize the application's PostgreSQL database. Runs inside the application pod. | | `DB_MIGRATE` | From GitLab 11.4, 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`. 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. Note that using quotes doesn't prevent word splitting. | ### Disable jobs The following table lists variables used to disable jobs. | **Job Name** | **CI/CDVariable** | **GitLab version** | **Description** | |----------------------------------------|---------------------------------|-----------------------|-----------------| | `.fuzz_base` | `COVFUZZ_DISABLED` | [From GitLab 13.2](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/34984) | [Read more](../../user/application_security/coverage_fuzzing/) about how `.fuzz_base` provide capability for your own jobs.

Some applications need to define secret variables that are accessible by the deployed application. Auto DevOps detects CI/CD variables starting with `K8S_SECRET_`, and makes these prefixed variables available to the deployed application as environment variables. To configure your application variables: 1. On the top bar, select **Menu > Projects** and find your project. 1. On the left sidebar, select **Settings > CI/CD**. 1. Expand **Variables**. 1. Create a CI/CD variable, ensuring the key is prefixed with `K8S_SECRET_`. For example, you can create a variable with key `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. Auto DevOps pipelines take 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. Following the example above, you can see the secret below containing the `RAILS_MASTER_KEY` variable. ```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 ``` Environment variables are generally considered immutable in a Kubernetes pod. If you update an application secret without changing any code, then manually create a new pipeline, any running application pods don't receive the updated secrets. To update the 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 currently supported due to limitations with the current Auto DevOps scripting environment. ### Advanced replica variables setup Apart from the two replica-related variables for production mentioned above, you can also use other variables for different environments. The Kubernetes' label named `track`, GitLab CI/CD environment names, and the replicas environment variable are combined into the format `TRACK_ENV_REPLICAS`, enabling you to define your own variables for scaling the pod's replicas: - `TRACK`: The capitalized value of the `track` [Kubernetes label](https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/) in the Helm Chart app definition. If not set, it isn't taken into account to the variable name. - `ENV`: The capitalized environment name of the deploy job, set in `.gitlab-ci.yml`. In the example below, the environment's name is `qa`, and it deploys the track `foo`, which results in an environment variable named `FOO_QA_REPLICAS`: ```yaml QA testing: stage: deploy environment: name: qa script: - deploy foo ``` The track `foo` being referenced must also be defined in the application's Helm chart, like: ```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 > [Introduced](https://gitlab.com/gitlab-org/gitlab-ci-yml/-/merge_requests/160) in GitLab 10.8. NOTE: You can also set this inside your [project's settings](requirements.md#auto-devops-deployment-strategy). The normal behavior of Auto DevOps is to use continuous deployment, pushing automatically to the `production` environment every time a new pipeline is run on the default branch. However, there are cases where you might want to use a staging environment, and deploy to production manually. For this scenario, the `STAGING_ENABLED` CI/CD variable was introduced. If you define `STAGING_ENABLED` with a non-empty value, then GitLab automatically deploys the application to a `staging` environment, and creates a `production_manual` job for you when you're ready to manually deploy to production. ### Deploy policy for canary environments **(PREMIUM)** > [Introduced](https://gitlab.com/gitlab-org/gitlab-ci-yml/-/merge_requests/171) in GitLab 11.0. You can use a [canary environment](../../user/project/canary_deployments.md) before deploying any changes to production. If you define `CANARY_ENABLED` with a non-empty value, then two manual jobs are created: - `canary` - Deploys the application to the canary environment. - `production_manual` - Manually deploys the application to production. ### Incremental rollout to production **(PREMIUM)** > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/5415) in GitLab 10.8. NOTE: You can also set this inside your [project's settings](requirements.md#auto-devops-deployment-strategy). When you're ready to deploy a new version of your app to production, you may want to use an incremental rollout to replace just a few pods with the latest code to check how the application is behaving before manually increasing the rollout up to 100%. If `INCREMENTAL_ROLLOUT_MODE` is set to `manual` in your project, then instead of the standard `production` job, 4 different [manual jobs](../../ci/pipelines/index.md#add-manual-interaction-to-your-pipeline) are created: 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 you want to have for your deployment. If the value is `10`, and you run the `10%` rollout job, there is `1` new pod and `9` old ones. To start a job, click the play icon (**{play}**) next to the job's name. You're not required to go from `10%` to `100%`, you can jump to whatever job you want. You can also scale down by running a lower percentage job, just before hitting `100%`. Once you get to `100%`, you can't scale down, and you'd have to roll back by redeploying the old version using the [rollback button](../../ci/environments/index.md#retry-or-roll-back-a-deployment) in the environment page. Below, you can see how the pipeline appears if the rollout or staging variables are defined. Without `INCREMENTAL_ROLLOUT_MODE` and without `STAGING_ENABLED`: ![Staging and rollout disabled](img/rollout_staging_disabled.png) 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`: ![Rollout enabled](img/rollout_enabled.png) With `INCREMENTAL_ROLLOUT_MODE` set to `manual` and with `STAGING_ENABLED` ![Rollout and staging enabled](img/rollout_staging_enabled.png) WARNING: Before GitLab 11.4, the presence of the `INCREMENTAL_ROLLOUT_ENABLED` CI/CD variable enabled this feature. This configuration is deprecated, and is scheduled to be removed in the future. ### Timed incremental rollout to production **(PREMIUM)** > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/7545) in GitLab 11.4. NOTE: You can also set this inside your [project's settings](requirements.md#auto-devops-deployment-strategy). This configuration is based on [incremental rollout to production](#incremental-rollout-to-production). Everything behaves the same way, except: - To enable it, set the `INCREMENTAL_ROLLOUT_MODE` CI/CD variable to `timed`. - Instead of the standard `production` job, the following jobs are created with a 5 minute delay between each: 1. `timed rollout 10%` 1. `timed rollout 25%` 1. `timed rollout 50%` 1. `timed rollout 100%` ## Auto DevOps banner The following Auto DevOps banner displays for users with Maintainer or greater permissions on new projects when Auto DevOps is not enabled: ![Auto DevOps banner](img/autodevops_banner_v12_6.png) The banner can be disabled for: - A user, when they dismiss it themselves. - A project, by explicitly [disabling Auto DevOps](index.md#enable-or-disable-auto-devops). - An entire GitLab instance: - By an administrator running the following in a Rails console: ```ruby Feature.enable(:auto_devops_banner_disabled) ``` - Through the REST API with an administrator access token: ```shell curl --data "value=true" --header "PRIVATE-TOKEN: " "https://gitlab.example.com/api/v4/features/auto_devops_banner_disabled" ```
