services / Kubernetes / ClusterRoleBindings

A ClusterRoleBinding is used to associate a ClusterRole with one or more principals (users, groups, or service accounts). It establishes a connection between a set of permissions defined in a ClusterRole and the entities that should have those permissions. ClusterRoles are scoped to the entire Kubernetes cluster.

ClusterRoles are only definitions of permissions. A role does not take effect unless assigned to principal via a ClusterRoleBinding.

Deleting a ClusterRoleBinding removes the permissions of the ClusterRole from a list of principals
