1.创建sc：

# cat csi-storageclass.yaml 
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: csi-hostpath-sc
provisioner: hostpath.csi.k8s.io
reclaimPolicy: Delete
volumeBindingMode: Immediate
allowVolumeExpansion: true

# kubectl apply -f csi-storageclass.yaml

# kubectl  get sc

NAME              PROVISIONER           RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE

csi-hostpath-sc   hostpath.csi.k8s.io   Delete          Immediate           true                   3d6h

2.创建pvc:

# cat csi-pvc.yaml 
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: csi-pvc2-vms3
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 15Gi
  storageClassName: csi-hostpath-sc # defined in csi-storageclass.yaml

# cat csi-pvc-block.yaml 
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: pvc-cen7.9-vms
spec:
  accessModes:
    - ReadWriteOnce
  storageClassName: csi-hostpath-sc
  volumeMode: Block
  resources:
    requests:
      storage: 100Gi

# kubectl apply -f csi-pvc.yaml

# kubectl  get pvc

csi-pvc2-vms3                                            Bound    pvc-9f4863ed-8d9a-4329-bc42-4f693ab15210   15Gi       RWO            csi-hostpath-sc   2d1h

# kubectl apply -f csi-pvc-block.yaml

# kubectl  get pvc

pvc-cen7.9-vms                                           Bound    pvc-d7943ef1-ef30-47ae-b8dc-b0116c480dcf   100Gi      RWO            csi-hostpath-sc   3s

3.pvc克隆：

    kind: PersistentVolumeClaim
    apiGroup: ""
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
