Tip: Want to provide a user with access to a specific project within a cluster? See Adding Project Members instead.
There are two contexts where you can add cluster members:
Adding Members to a New Cluster
You can add members to a cluster as you create it (recommended if possible).
You can always add members to a cluster after a cluster is provisioned.
