# Define the settings for the rook-ceph cluster with common settings for a small test cluster.
# All nodes with available raw devices will be used for the Ceph cluster. One node is sufficient
# in this example.

# For example, to create the cluster:
#   kubectl create -f crds.yaml -f common.yaml -f operator.yaml
#   kubectl create -f cluster-test.yaml
