doc/ci/autodeploy/index.md

-# Auto Deploy
-
-> [Introduced][mr-8135] in GitLab 8.15.
-> Auto deploy is an experimental feature and is **not recommended for Production use** at this time.
-
-> As of GitLab 9.1, access to the container registry is only available while the
-Pipeline is running. Restarting a pod, scaling a service, or other actions which
-require on-going access **will fail**. On-going secure access is planned for a
-subsequent release.
-
-> As of GitLab 10.0, Auto Deploy templates are **deprecated** and the
-functionality has been included in [Auto
-DevOps](../../topics/autodevops/index.md).
-
-Auto deploy is an easy way to configure GitLab CI for the deployment of your
-application. GitLab Community maintains a list of `.gitlab-ci.yml`
-templates for various infrastructure providers and deployment scripts
-powering them. These scripts are responsible for packaging your application,
-setting up the infrastructure and spinning up necessary services (for
-example a database).
-
-## How it works
-
-The Autodeploy templates are based on the [kubernetes-deploy][kube-deploy]
-project which is used to simplify the deployment process to Kubernetes by
-providing intelligent `build`, `deploy`, and `destroy` commands which you can
-use in your `.gitlab-ci.yml` as is. It uses [Herokuish](https://github.com/gliderlabs/herokuish),
-which uses [Heroku buildpacks](https://devcenter.heroku.com/articles/buildpacks)
-to do some of the work, plus some of GitLab's own tools to package it all up. For
-your convenience, a [Docker image][kube-image] is also provided.
-
-You can use the [Kubernetes project service](../../user/project/integrations/kubernetes.md)
-to store credentials to your infrastructure provider and they will be available
-during the deployment.
-
-## Quick start
-
-We made a [simple guide](quick_start_guide.md) to using Auto Deploy with GitLab.com.
-
-For a demonstration of GitLab Auto Deploy, read the blog post [Auto Deploy from GitLab to an OpenShift Container Cluster](https://about.gitlab.com/2017/05/16/devops-containers-gitlab-openshift/)
-
-## Supported templates
-
-The list of supported auto deploy templates is available in the
-[gitlab-ci-yml project][auto-deploy-templates].
-
-## Configuration
-
->**Note:**
-In order to understand why the following steps are required, read the
-[how it works](#how-it-works) section.
-
-To configure Autodeploy, you will need to:
-
-1. Enable a deployment [project service][project-services] to store your
-   credentials. For example, if you want to deploy to OpenShift you have to
-   enable [Kubernetes service][kubernetes-service].
-1. Configure GitLab Runner to use the
-   [Docker or Kubernetes executor](https://docs.gitlab.com/runner/executors/) with
-   [privileged mode enabled][docker-in-docker].
-1. Navigate to the "Project" tab and click "Set up auto deploy" button.
-   ![Auto deploy button](img/auto_deploy_button.png)
-1. Select a template.
-  ![Dropdown with auto deploy templates](img/auto_deploy_dropdown.png)
-1. Commit your changes and create a merge request.
-1. Test your deployment configuration using a [Review App][review-app] that was
-   created automatically for you.
-
-## Private project support
-
-> Experimental support [introduced][mr-2] in GitLab 9.1.
-
-When a project has been marked as private, GitLab's [Container Registry][container-registry] requires authentication when downloading containers. Auto deploy will automatically provide the required authentication information to Kubernetes, allowing temporary access to the registry. Authentication credentials will be valid while the pipeline is running, allowing for a successful initial deployment.
-
-After the pipeline completes, Kubernetes will no longer be able to access the container registry. Restarting a pod, scaling a service, or other actions which require on-going access to the registry will fail. On-going secure access is planned for a subsequent release.
-
-## PostgreSQL database support
-
-> Experimental support [introduced][mr-8] in GitLab 9.1.
-
-In order to support applications that require a database, [PostgreSQL][postgresql] is provisioned by default. Credentials to access the database are preconfigured, but can be customized by setting the associated [variables](#postgresql-variables). These credentials can be used for defining a `DATABASE_URL` of the format: `postgres://user:password@postgres-host:postgres-port/postgres-database`. It is important to note that the database itself is temporary, and contents will be not be saved.
-
-PostgreSQL provisioning can be disabled by setting the variable `DISABLE_POSTGRES` to `"yes"`.
-
-The following PostgreSQL variables are supported:
-
-1. `DISABLE_POSTGRES: "yes"`: disable automatic deployment of PostgreSQL
-1. `POSTGRES_USER: "my-user"`: use custom username for PostgreSQL
-1. `POSTGRES_PASSWORD: "password"`: use custom password for PostgreSQL
-1. `POSTGRES_DB: "my database"`: use custom database name for PostgreSQL
-
-## Auto Monitoring
-
-> Introduced in [GitLab 9.5](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/13438).
-
-Apps auto-deployed using one the [Kubernetes templates](#supported-templates) can also be automatically monitored for:
-
-* Response Metrics: latency, throughput, error rate
-* System Metrics: CPU utilization, memory utilization
-
-Metrics are gathered from [nginx-ingress](../../user/project/integrations/prometheus_library/nginx_ingress.md) and [Kubernetes](../../user/project/integrations/prometheus_library/kubernetes.md).
-
-To view the metrics, open the [Monitoring dashboard for a deployed environment](../environments.md#monitoring-environments).
-
-![Auto Metrics](img/auto_monitoring.png)
-
-### Configuring Auto Monitoring
-
-If GitLab has been deployed using the [omnibus-gitlab](../../install/kubernetes/gitlab_omnibus.md) Helm chart, no configuration is required.
-
-If you have installed GitLab using a different method:
-
-1. [Deploy Prometheus](../../user/project/integrations/prometheus.md#configuring-your-own-prometheus-server-within-kubernetes) into your Kubernetes cluster
-1. If you would like response metrics, ensure you are running at least version 0.9.0 of NGINX Ingress and [enable Prometheus metrics](https://github.com/kubernetes/ingress/blob/master/examples/customization/custom-vts-metrics/nginx/nginx-vts-metrics-conf.yaml).
-1. Finally, [annotate](https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations/) the NGINX Ingress deployment to be scraped by Prometheus using `prometheus.io/scrape: "true"` and `prometheus.io/port: "10254"`.

-# GitLab Kubernetes / OpenShift integration
-
-CAUTION: **Warning:**
-The Kubernetes service integration has been deprecated in GitLab 10.3. If the
-service is active, the cluster information will still be editable, however we
-advise to disable and reconfigure the clusters using the new
-[Clusters](../clusters/index.md) page. If the service is inactive, the fields
-will not be editable. Read [GitLab 10.3 release post](https://about.gitlab.com/2017/12/22/gitlab-10-3-released/#kubernetes-integration-service) for more information.
-
-GitLab can be configured to interact with Kubernetes, or other systems using the
-Kubernetes API (such as OpenShift).
-
-Each project can be configured to connect to a different Kubernetes cluster, see
-the [configuration](#configuration) section.
-
-## Configuration
-
-Navigate to the [Integrations page](project_services.md#accessing-the-project-services)
-of your project and select the **Kubernetes** service to configure it. Fill in
-all the needed parameters, check the "Active" checkbox and hit **Save changes**
-for the changes to take effect.
-
-![Kubernetes configuration settings](img/kubernetes_configuration.png)
-
-The Kubernetes service takes the following parameters:
-
-- **API URL** -
-  It's the URL that GitLab uses to access the Kubernetes API. Kubernetes
-  exposes several APIs, we want the "base" URL that is common to all of them,
-  e.g., `https://kubernetes.example.com` rather than `https://kubernetes.example.com/api/v1`.
-- **CA certificate** (optional) -
-  If the API is using a self-signed TLS certificate, you'll also need to include
-  the `ca.crt` contents here.
-- **Project namespace** (optional) - The following apply:
-  - By default you don't have to fill it in; by leaving it blank, GitLab will
-    create one for you.
-  - Each project should have a unique namespace.
-  - The project namespace is not necessarily the namespace of the secret, if
-    you're using a secret with broader permissions, like the secret from `default`.
-  - You should **not** use `default` as the project namespace.
-  - If you or someone created a secret specifically for the project, usually
-    with limited permissions, the secret's namespace and project namespace may
-    be the same.
-- **Token** -
-  GitLab authenticates against Kubernetes using service tokens, which are
-  scoped to a particular `namespace`. If you don't have a service token yet,
-  you can follow the
-  [Kubernetes documentation](https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/)
-  to create one. You can also view or create service tokens in the
-  [Kubernetes dashboard](https://kubernetes.io/docs/tasks/access-application-cluster/web-ui-dashboard/#config)
-  (under **Config > Secrets**).
-
-TIP: **Tip:**
-If you have a single cluster that you want to use for all your projects,
-you can pre-fill the settings page with a default template. To configure the
-template, see [Services Templates](services_templates.md).
-
-## Deployment variables
-
-The Kubernetes service exposes the following
-[deployment variables](../../../ci/variables/README.md#deployment-variables) in the
-GitLab CI/CD build environment:
-
-- `KUBE_URL` - Equal to the API URL.
-- `KUBE_TOKEN` - The Kubernetes token.
-- `KUBE_NAMESPACE` - The Kubernetes namespace is auto-generated if not specified.
-  The default value is `<project_name>-<project_id>`. You can overwrite it to
-  use different one if needed, otherwise the `KUBE_NAMESPACE` variable will
-  receive the default value.
-- `KUBE_CA_PEM_FILE` - Only present if a custom CA bundle was specified. Path
-  to a file containing PEM data.
-- `KUBE_CA_PEM` (deprecated) - Only if a custom CA bundle was specified. Raw PEM data.
-- `KUBECONFIG` - Path to a file containing `kubeconfig` for this deployment.
-  CA bundle would be embedded if specified.
-
-## What you can get with the Kubernetes integration
-
-Here's what you can do with GitLab if you enable the Kubernetes integration.
-
-### Deploy Boards
-
-> Available in [GitLab Premium][ee].
-
-GitLab's Deploy Boards offer a consolidated view of the current health and
-status of each CI [environment](../../../ci/environments.md) running on Kubernetes,
-displaying the status of the pods in the deployment. Developers and other
-teammates can view the progress and status of a rollout, pod by pod, in the
-workflow they already use without any need to access Kubernetes.
-
-[> Read more about Deploy Boards](https://docs.gitlab.com/ee/user/project/deploy_boards.html)
-
-### Canary Deployments
-
-> Available in [GitLab Premium][ee].
-
-Leverage [Kubernetes' Canary deployments](https://kubernetes.io/docs/concepts/cluster-administration/manage-deployment/#canary-deployments)
-and visualize your canary deployments right inside the Deploy Board, without
-the need to leave GitLab.
-
-[> Read more about Canary Deployments](https://docs.gitlab.com/ee/user/project/canary_deployments.html)
-
-### Kubernetes monitoring
-
-Automatically detect and monitor Kubernetes metrics. Automatic monitoring of
-[NGINX ingress](./prometheus_library/nginx.md) is also supported.
-
-[> Read more about Kubernetes monitoring](prometheus_library/kubernetes.md)
-
-### Auto DevOps
-
-Auto DevOps automatically detects, builds, tests, deploys, and monitors your
-applications.
-
-To make full use of Auto DevOps(Auto Deploy, Auto Review Apps, and Auto Monitoring)
-you will need the Kubernetes project integration enabled.
-
-[> Read more about Auto DevOps](../../../topics/autodevops/index.md)
-
-### Web terminals
-
-NOTE: **Note:**
-Introduced in GitLab 8.15. You must be the project owner or have `master` permissions
-to use terminals. Support is limited to the first container in the
-first pod of your environment.
-
-When enabled, the Kubernetes service adds [web terminal](../../../ci/environments.md#web-terminals)
-support to your [environments](../../../ci/environments.md). This is based on the `exec` functionality found in
-Docker and Kubernetes, so you get a new shell session within your existing
-containers. To use this integration, you should deploy to Kubernetes using
-the deployment variables above, ensuring any pods you create are labelled with
-`app=$CI_ENVIRONMENT_SLUG`. GitLab will do the rest!
