# Define the settings for the rook-ceph-external cluster with common settings for a production cluster.

# For example, if Rook is not managing any existing cluster in the 'rook-ceph' namespace do:
#   kubectl create -f crds.yaml -f common.yaml -f operator.yaml
#   kubectl create -f cluster-external.yaml

# If there is already a cluster managed by Rook in 'rook-ceph' then do:
#   kubectl create -f common-external.yaml
#   kubectl create -f cluster-external.yaml
