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:
## Adding and creating a new GKE cluster via GitLab
- `app.gitlab.com/env: $CI_ENVIRONMENT_SLUG`
- `app.gitlab.com/app: $CI_PROJECT_PATH_SLUG`
`$CI_ENVIRONMENT_SLUG` and `$CI_PROJECT_PATH_SLUG` are the values of
the CI variables.
## Adding and removing clusters
There are two options when adding a new cluster to your project:
- Associate your account with Google Kubernetes Engine (GKE) to
[create new clusters](#add-new-gke-cluster) from within GitLab.
- Provide credentials to an
[existing Kubernetes cluster](#add-existing-kubernetes-cluster).

### Setting the environment scope **(PREMIUM)**
When adding more than one Kubernetes cluster to your project, you need to differentiate
them with an environment scope. The environment scope associates clusters with [environments](../../../ci/environments.md) similar to how the
[environment-specific variables](../../../ci/variables/README.md#limiting-environment-scopes-of-environment-variables-premium) work.
The default environment scope is `*`, which means all jobs, regardless of their
environment, will use that cluster. Each scope can only be used by a single
cluster in a project, and a validation error will occur if otherwise.
Also, jobs that don't have an environment keyword set will not be able to access any cluster.
For example, let's say the following Kubernetes clusters exist in a project:
| Cluster | Environment scope |
| ----------- | ----------------- |
| Development | `*` |
| Staging | `staging` |
| Production | `production` |
And the following environments are set in [`.gitlab-ci.yml`](../../../ci/yaml/README.md):
```yaml
stages:
- test
- deploy
test:
stage: test
script: sh test
deploy to staging:
stage: deploy

environment:
name: staging
url: https://staging.example.com/
deploy to production:
stage: deploy
script: make deploy
environment:
name: production
url: https://example.com/
```
The result will then be:
- The development cluster will be used for the "test" job.
- The staging cluster will be used for the "deploy to staging" job.
- The production cluster will be used for the "deploy to production" job.
### Multiple Kubernetes clusters **(PREMIUM)**

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!
