# Define the settings for the rook-ceph cluster with common settings for a production cluster on top of bare metal.
# This example expects three nodes, each with two available disks. Please modify it according to your environment.
# See the documentation for more details on storage settings available.
# For example, to create the cluster:
# kubectl create -f crds.yaml -f common.yaml -f operator.yaml
# kubectl create -f cluster-on-local-pvc.yaml
