RoleBinding references a role, but does not contain it. It can reference a Role in the same namespace or a ClusterRole in the global namespace. It adds who information via Subjects and namespace information by which namespace it exists in. RoleBindings in a given namespace only have effect in that namespace.
We don't have any examples of RoleBinding yet 😕
Please let us know if you would like to see some examples of how to create a RoleBinding.
