 ClusterRole / ClusterRoleBinding:: A `ClusterRole` represents a set of permissions at the cluster level that can be used by multiple namespaces. The `ClusterRoleBinding` is used for granting the permissions defined in a `ClusterRole` to a user or group of users at a namespace level. Applications are not permitted to install cluster roles or create cluster role bindings. This is an administrative activity done by cluster administrators. Workloads should not use cluster roles; exceptions can be granted to allow this, however this is discouraged.
