Chapter 10. Configuring a specific cluster management role

When you install Red Hat Advanced Cluster Management for Kubernetes, the default configuration provides the cluster-admin role on the Red Hat Advanced Cluster Management hub cluster. This permission enables you to create, manage, and import managed clusters on the hub cluster. In some situations, you might want to limit the access to certain managed clusters that are managed by the hub cluster, rather than providing access to all of the managed clusters on the hub cluster.

You can limit access to certain managed clusters by defining a cluster role and applying it to a user or group. Complete the following steps to configure and apply a role:

  1. Define the cluster role by creating a YAML file with the following content: 

    apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: <clusterrole-name>
rules:
- apiGroups:
  - cluster.open-cluster-management.io
  resources:
  - managedclusters
  resourceNames:
  - <managed-cluster-name>
  verbs:
  - get
  - list
  - watch
  - update
  - delete
  - deletecollection
  - patch
- apiGroups:
  - cluster.open-cluster-management.io
  resources:
  - managedclusters
  verbs:
  - create
- apiGroups:
  - ""
  resources:
  - namespaces
  resourceNames:
  - <managed-cluster-name>
  verbs:
  - create
  - get
  - list
  - watch
  - update
  - delete
  - deletecollection
  - patch
- apiGroups:
  - register.open-cluster-management.io
  resources:
  - managedclusters/accept
  resourceNames:
  - <managed-cluster-name>
  verbs:
  - update
    Copy to Clipboard Toggle word wrap

    Replace clusterrole-name with the name of the cluster role that you are creating.

    Replace managed-cluster-name with the name of the managed cluster that you want the user to have access to.

  2. Apply the clusterrole definition by entering the following command: 

    oc apply <filename>
    Copy to Clipboard Toggle word wrap

    Replace filename with the name of the YAML file that you created in the previous step.

  3. Enter the following command to bind the clusterrole to a specified user or group: 

    oc adm policy add-cluster-role-to-user <clusterrole-name> <username>
    Copy to Clipboard Toggle word wrap

    Replace clusterrole-name with the name of the cluster role that you applied in the previous step. Replace username with the username to which you want to bind the cluster role.
