7.6. Adding roles to users

Procedure

1. Add a role to a user in a specific project:

   $ oc adm policy add-role-to-user <role> <user> -n <project>

   For example, you can add the admin role to the alice user in joe project by running:

   $ oc adm policy add-role-to-user admin alice -n joe

   You can alternatively apply the following YAML to add the role to the user:

   apiVersion: rbac.authorization.k8s.io/v1
   kind: RoleBinding
   metadata:
     name: admin-0
     namespace: joe
   roleRef:
     apiGroup: rbac.authorization.k8s.io
     kind: ClusterRole
     name: admin
   subjects:
   - apiGroup: rbac.authorization.k8s.io
     kind: User
     name: alice

2. View the local role bindings and verify the addition in the output:

   $ oc describe rolebinding.rbac -n <project>

   For example, to view the local role bindings for the joe project:

   $ oc describe rolebinding.rbac -n joe

   Example output
