-Connect your project to Google Kubernetes Engine (GKE) or an existing Kubernetes
-cluster in a few steps.
+GitLab provides many features with a Kubernetes integration. Kubernetes can be
+integrated with projects, but also:
+
+- [Groups](../../group/clusters/index.md).
+- [Instances](../../instance/clusters/index.md).
 
 NOTE: **Scalable app deployment with GitLab and Google Cloud Platform**
 [Watch the webcast](https://about.gitlab.com/webcast/scalable-app-deploy/) and learn how to spin up a Kubernetes cluster managed by Google Cloud Platform (GCP) in a few clicks.
 
 ## Overview
 
-With one or more Kubernetes clusters associated to your project, you can use
-[Review Apps](../../../ci/review_apps/index.md), deploy your applications, run
-your pipelines, use it with [Auto DevOps](../../../topics/autodevops/index.md),
-and much more, all from within GitLab.
+Using the GitLab project Kubernetes integration, you can:
+
+- Use [Review Apps](../../../ci/review_apps/index.md).
+- Run [pipelines](../../../ci/pipelines.md).
+- [Deploy](#deploying-to-a-kubernetes-cluster) your applications.
+- Detect and [monitor Kubernetes](#kubernetes-monitoring).
+- Use it with [Auto DevOps](#auto-devops).
+- Use [Web terminals](#web-terminals).
+- Use [Deploy Boards](#deploy-boards-premium). **(PREMIUM)**
+- Use [Canary Deployments](#canary-deployments-premium). **(PREMIUM)**
+- View [Pod logs](#pod-logs-ultimate). **(ULTIMATE)**
+
+You can also:
+
+- Connect and deploy to an [Amazon EKS cluster](eks_and_gitlab/index.html).
+- Run serverless workloads on [Kubernetes with Knative](serverless/index.md).
+
+### Deploy Boards **(PREMIUM)**
+
+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](../deploy_boards.md)
+
+### Canary Deployments **(PREMIUM)**
+
+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](../canary_deployments.md)
+
+### Pod logs **(ULTIMATE)**
+
+GitLab makes it easy to view the logs of running pods in connected Kubernetes clusters. By displaying the logs directly in GitLab, developers can avoid having to manage console tools or jump to a different interface.
+
+[Read more about Kubernetes pod logs](kubernetes_pod_logs.md)
+
+### Kubernetes monitoring
 
-There are two options when adding a new cluster to your project; either associate
-your account with Google Kubernetes Engine (GKE) so that you can [create new
-clusters](#adding-and-creating-a-new-gke-cluster-via-gitlab) from within GitLab,
-or provide the credentials to an [existing Kubernetes cluster](#adding-an-existing-kubernetes-cluster).
+Automatically detect and monitor Kubernetes metrics. Automatic monitoring of
+[NGINX ingress](../integrations/prometheus_library/nginx.md) is also supported.
+
+[Read more about Kubernetes monitoring](../integrations/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:**
-From [GitLab 11.6](https://gitlab.com/gitlab-org/gitlab-ce/issues/34758) you
-can also associate a Kubernetes cluster to your groups and from
-[GitLab 11.11](https://gitlab.com/gitlab-org/gitlab-ce/issues/39840),
-to the GitLab instance. Learn more about [group-level](../../group/clusters/index.md)
-and [instance-level](../../instance/clusters/index.md) Kubernetes clusters.
+Introduced in GitLab 8.15. You must be the project owner or have `maintainer` 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 deployments, replica sets, and
+pods are annotated with:

 When [Prometheus is deployed](#installing-applications), GitLab will automatically monitor the cluster's health. At the top of the cluster settings page, CPU and Memory utilization is displayed, along with the total amount available. Keeping an eye on cluster resources can be important, if the cluster runs out of memory pods may be shutdown or fail to start.

-## Enabling or disabling the Kubernetes cluster integration
-
-After you have successfully added your cluster information, you can enable the
-Kubernetes cluster integration:
-
-1. Click the **Enabled/Disabled** switch
-1. Hit **Save** for the changes to take effect
-
-You can now start using your Kubernetes cluster for your deployments.
-
-To disable the Kubernetes cluster integration, follow the same procedure.
-
-## Removing the Kubernetes cluster integration
-
-NOTE: **Note:**
-You need Maintainer [permissions] and above to remove a Kubernetes cluster integration.
-
-NOTE: **Note:**
-When you remove a cluster, you only remove its relation to GitLab, not the
-cluster itself. To remove the cluster, you can do so by visiting the GKE
-dashboard or using `kubectl`.
-
-To remove the Kubernetes cluster integration from your project, simply click the
-**Remove integration** button. You will then be able to follow the procedure
-and add a Kubernetes cluster again.
-
-## What you can get with the Kubernetes integration
-
-Here's what you can do with GitLab if you enable the Kubernetes integration.
-
-### Deploy Boards **(PREMIUM)**
-
-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](../deploy_boards.md)
-
-### Canary Deployments **(PREMIUM)**
-
-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](../canary_deployments.md)
-
-### Pod logs **(ULTIMATE)**
-
-GitLab makes it easy to view the logs of running pods in connected Kubernetes clusters. By displaying the logs directly in GitLab, developers can avoid having to manage console tools or jump to a different interface.
-
-[Read more about Kubernetes pod logs](kubernetes_pod_logs.md)
-
-### Kubernetes monitoring
-
-Automatically detect and monitor Kubernetes metrics. Automatic monitoring of
-[NGINX ingress](../integrations/prometheus_library/nginx.md) is also supported.
-
-[Read more about Kubernetes monitoring](../integrations/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 `maintainer` 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!
