Usage

For more detailed usage instructions, run

kubectl gitlab help

In the below examples, $project and $group can be either IDs or paths.

Add existing cluster to GitLab

kubectl gitlab --project $project add
kubectl gitlab --group $group add
kubectl gitlab --instance add

The add command also creates a service account gitlab-admin and a cluster role binding gitlab-admin in the kube-system namespace.

List clusters associated with GitLab

kubectl gitlab --project $project list
kubectl gitlab --group $group list
kubectl gitlab --instance list

Remove cluster association from GitLab

kubectl gitlab --project $project delete $cluster_id
kubectl gitlab --group $group delete $cluster_id
kubectl gitlab --instance delete $cluster_id

Note: This does not delete the service account and role binding created when the cluster was added. You can delete those separately via

kubectl -n kube-system delete clusterrolebinding gitlab-admin
kubectl -n kube-system delete serviceaccount gitlab-admin

Configuration

Authentication

A GitLab API token with the api scope is required, specified as either

• the environment variable GITLAB_TOKEN, or
• the flag --gitlab-token

Custom base URL

By default, requests go to https://gitlab.com. You can customize this with

• the environment variable GITLAB_URL, or
• the flag --gitlab-url
