Cluster Creation

The Rook operator performs the following operations when the CephCluster CR is created in external mode:

• The operator validates that a connection is available to the remote Ceph cluster. The connection requires mon endpoints and secrets to be imported into the local cluster.

• The CSI driver is configured with the remote connection to Ceph. The RBD and CephFS provisioners and volume plugins are started similarly to the CSI driver when configured in internal mode, the connection to Ceph happens to be external to the OpenShift cluster.

• Periodically watch for monitor address changes and update the Ceph-CSI configuration accordingly.
