apiVersion: v1
kind: ServiceAccount
metadata:
  name: nfs-client-provisioner
  # replace with namespace where provisioner is deployed
  namespace: default
---
kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:

    namespace: default
roleRef:

  apiGroup: rbac.authorization.k8s.io

然后我们部署下NFS-Subdir-External-Provisioner的deployment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nfs-client-provisioner
  labels:
    app: nfs-client-provisioner
  # replace with namespace where provisioner is deployed
  namespace: default
spec:
  replicas: 1
  strategy:
    type: Recreate
  selector:
    matchLabels:
      app: nfs-client-provisioner
  template:
    metadata:
      labels:
        app: nfs-client-provisioner
    spec:
      serviceAccountName: nfs-client-provisioner
      containers:
        - name: nfs-client-provisioner
          image: ccr.ccs.tencentyun.com/niewx-k8s/nfs-subdir-external-provisioner:v4.0.2
          volumeMounts:
            - name: nfs-client-root
              mountPath: /persistentvolumes
          env:
            - name: PROVISIONER_NAME
              value: k8s-sigs.io/nfs-subdir-external-provisioner  ## Provisioner的名称,以后设置的storageclass要和这个保持一致
            - name: NFS_SERVER  ## NFS服务器地址,需和valumes参数中配置的保持一致
              value: 10.0.8.6
            - name: NFS_PATH  ## NFS服务器数据存储目录,需和valumes参数中配置的保持一致
              value: /nfs/data
      volumes:
        - name: nfs-client-root
          nfs:
            server: 10.0.8.6 ## NFS服务器地址
            path: /nfs/data ## NFS服务器数据存储目录

接下来我们创建下StorageClass

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: nfs-client
  annotations:
    storageclass.kubernetes.io/is-default-class: "false" # 是否设置为默认的storageclass
provisioner: k8s-sigs.io/nfs-subdir-external-provisioner # or choose another name, must match deployment's env PROVISIONER_NAME'
parameters:
  archiveOnDelete: "false" # 设置为"false"时删除PVC不会保留数据,"true"则保留数据
mountOptions:
  - hard # 指定为硬挂载方式
  - nfsvers=4 # 指定NFS版本,这个需要根据NFS Server版本号设置，可以nfsstat -m查看

3. 测试创建pod通过pvc挂载

首先创建下pvc

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: test-claim
spec:
  storageClassName: nfs-client
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 1Mi

创建deploy挂载这个pvc

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    k8s-app: nfs-volume-test
    qcloud-app: nfs-volume-test
  name: nfs-volume-test
  namespace: default
spec:
  replicas: 1
  selector:
    matchLabels:
      k8s-app: nfs-volume-test
      qcloud-app: nfs-volume-test
  strategy:
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 0
    type: RollingUpdate
  template:
    metadata:
      labels:
        k8s-app: nfs-volume-test
        qcloud-app: nfs-volume-test
    spec:
      containers:
      - image: nginx:latest
        imagePullPolicy: Always
        name: nfs-volume-test
        resources: {}
        securityContext:
          privileged: false
        volumeMounts:
        - mountPath: /tmp
          name: vol
      dnsPolicy: ClusterFirst
      restartPolicy: Always
      schedulerName: default-scheduler
      securityContext: {}
      terminationGracePeriodSeconds: 30
      volumes:
      - name: vol
        persistentVolumeClaim:
          claimName: test-claim
