+Before Rook can start provisioning storage, a StorageClass and its storage pool need to be created. This is needed for Kubernetes to interoperate with Rook for provisioning persistent volumes. The rook-storageclass.yaml sample will create the storage pool automatically. For more options on pools, see the documentation on [creating storage pools](pool-tpr.md).
 
-First create the storage pool. See the documentation on [creating storage pools](pool-tpr.md).

-kubectl create -f rook-pool.yaml

-Rook already creates a default admin and rbd user, whose secrets are already specified in the sample [rook-storageclass.yaml](/demo/kubernetes/rook-storageclass.yaml). Now we just need to specify the Ceph monitor endpoints (requires `jq`):
