-| `ROLLOUT_RESOURCE_TYPE` | 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` | 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. |
-
-NOTE:
-After you set up your replica variables using a

-you can scale your application by redeploying it.
-
-WARNING:
-You should *not* scale your application using Kubernetes directly. This can

-### Application secret variables
-
-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 **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, 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
-
-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)**
-
-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)**
-
-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, select 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.

-### Timed incremental rollout to production **(PREMIUM)**
-
-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%`
