Role-based access control authentication to Back Up and Restore a Kubernetes Cluster Heptio Ark

kubectl create clusterrolebinding cluster-admin-binding --clusterrole cluster-admin --user [email protected]`


Error from server (Forbidden): is forbidden: User "[email protected]" cannot create resource "clusterrolebindings" in API group "" at the cluster scope
