4.4. Cluster Permissions

A cluster administrator has system administrator permissions for a specific cluster only. This is a hierarchical model, which means that a user assigned the cluster administrator role for a cluster can manage all objects in that cluster. The cluster administrator role permits the following actions:
  • Creation and removal of specific clusters.
  • Addition and removal of hosts.
  • Permission to attach users to hosts within a single cluster.
This is useful when there are multiple clusters, each of which require their own system administrators. A cluster administrator has permissions for the assigned cluster only, not for all clusters.

Note

You can only assign roles and permissions to existing users.
