       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/)
-      (under **Config > Secrets**). **The account that will issue the service token
-      must have admin privileges on the cluster.**
+      scoped to a particular `namespace`.
+      **The token used should belong to a service account with
+      [`cluster-admin`](https://kubernetes.io/docs/reference/access-authn-authz/rbac/#user-facing-roles)
+      privileges.** To create this service account:
+
+      1. Create a `gitlab` service account in the `default` namespace:
+
+          ```bash
+          kubectl create -f - <<EOF
+            apiVersion: v1
+            kind: ServiceAccount
+            metadata:

+              namespace: default
+          EOF
+          ```
+      1. Create a cluster role binding to give the `gitlab` service account
+         `cluster-admin` privileges:
+
+          ```bash
+          kubectl create -f - <<EOF
+          kind: ClusterRoleBinding
+          apiVersion: rbac.authorization.k8s.io/v1

+            apiGroup: rbac.authorization.k8s.io
+          EOF
+          ```
+      NOTE: **Note:**
+      For GKE clusters, you will need the

+      role binding. You can follow the [Google Cloud
