Currently, we need to configure the Ceph external Admin keyi in the Rook deployment to be able to connect to an external Ceph cluster. If we wanted to run in a multi-tenant fashion were several K8s/Rook clusters wanted to connect to the same external ceph cluster, each K8s deployment would have the access to the External Ceph Admin key and could potentially access or delete the Data from pools that belong to other k8s/Rook Clusters. Now the admin key is optional but the helper script create-external-cluster-resources.sh will help create the necessary keys/users to connect to that cluster. Closes: https://github.com/rook/rook/issues/4917 and https://github.com/rook/rook/pull/5227 Signed-off-by: Sébastien Han <seb@redhat.com>
