Creating a Storage Class

1. Create a csi-rbd-sc.yaml file.

   vi csi-rbd-sc.yaml

2. Press i to enter the insert mode and add the following content to the csi-rbd-sc.yaml file: Set clusterID to the FSID obtained in 2.

   --- 
   apiVersion: storage.k8s.io/v1 
   kind: StorageClass 
   metadata: 
     name: csi-rbd-sc 
   provisioner: rbd.csi.ceph.com 
   parameters: 
     clusterID: c2c76878-2c57-4b1c-ae9c-1cda797a1753 
     pool: kubernetes 
     csi.storage.k8s.io/provisioner-secret-name: csi-rbd-secret 
     csi.storage.k8s.io/provisioner-secret-namespace: default 
     csi.storage.k8s.io/node-stage-secret-name: csi-rbd-secret 
     csi.storage.k8s.io/node-stage-secret-namespace: default 
     csi.storage.k8s.io/controller-expand-secret-name: csi-rbd-secret 
     csi.storage.k8s.io/controller-expand-secret-namespace: default 
     imageFeatures: layering 
   reclaimPolicy: Delete 
   allowVolumeExpansion: true 
   mountOptions: 
   - discard

3. Press Esc to exit the insert mode. Type :wq! and press Enter to save the file and exit.
4. Use the YAML file to create a storage class.
