# Install GitLab Runner with Kubernetes Agent **(PREMIUM ONLY)**

These instructions to install GitLab Runner assume the
[GitLab Kubernetes Agent](https://docs.gitlab.com/ee/user/clusters/agent/index.html) is already configured.

1. Review the possible [GitLab Runner chart YAML values](https://gitlab.com/gitlab-org/charts/gitlab-runner/blob/main/values.yaml).
1. Create a `runner-chart-values.yaml` file with the configuration that fits
   your needs, such as:

   ```yaml
   # The GitLab Server URL (with protocol) that want to register the runner against
   # ref: https://docs.gitlab.com/runner/commands/README.html#gitlab-runner-register
   #
   gitlabUrl: https://gitlab.my.domain.example.com/

   # The Registration Token for adding new runners to the GitLab Server. This must
   # be retrieved from your GitLab instance.
   # ref: https://docs.gitlab.com/ce/ci/runners/README.html
   #
   runnerRegistrationToken: "yrnZW46BrtBFqM7xDzE7dddd"

   # For RBAC support:
   rbac:
       create: true

   # Run all containers with the privileged flag enabled
   # This will allow the docker:dind image to run if you need to run Docker
   # commands. Please read the docs before turning this on:
   # ref: https://docs.gitlab.com/runner/executors/kubernetes.html#using-dockerdind
   runners:
       privileged: true
   ```

1. Create a single manifest file to install the GitLab Runner chart with your cluster agent,
   replacing `GITLAB GITLAB-RUNNER` with your namespace:

   ```shell
   helm template --namespace GITLAB GITLAB-RUNNER -f runner-chart-values.yaml gitlab/gitlab-runner > runner-manifest.yaml
   ```

   An [example file is available](#example-runner-manifest).

1. Push your `runner-manifest.yaml` to your manifest repository.

## Example runner manifest

This code is an example of a runner manifest looks like.
Create your own `manifest.yaml` file to meet your project's needs.
