如果不想将nfs-provisioner部署在default，则执行下面操作(假设部署在nfs)

[root@master1 nfs]# kubectl create ns nfs
[root@master1 nfs]# sed -i 's/namespace: default/namespace: nfs/g' nfs-rbac.yml
[root@master1 nfs]# kubectl apply -f nfs-rbac.yml -n nfs

nfs-provisioner部署文件 nfs-provisioner.yaml

！！！配置nfs服务器地址和共享的出来的路径

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nfs-client-provisioner-one
  labels:
    app: nfs-client-provisioner-one
spec:
  replicas: 1
  strategy:
    type: Recreate
  selector:
    matchLabels:
      app: nfs-client-provisioner-one
  template:
    metadata:
      labels:
        app: nfs-client-provisioner-one
    spec:
      serviceAccountName: nfs-client-provisioner-one
      containers:
        - name: nfs-client-provisioner-one
          #！！！修改值---镜像
          image: 172.16.15.250/nfs-client-provisioner
          volumeMounts:
            - name: nfs-client-root
              mountPath: /persistentvolumes
          env:
            - name: PROVISIONER_NAME
              #！！！修改值---后续创建storageclass时需要用到该参数
              value: nfsone
            - name: NFS_SERVER
              #！！！修改值---nfs服务器地址
              value: 172.16.15.121
            - name: NFS_PATH
              #！！！修改值---nfs共享出来的路径
              value: /data-nfs
      volumes:
        - name: nfs-client-root
          nfs:
            #！！！修改值---nfs服务器地址
            server: 172.16.15.121
            #！！！修改值---nfs共享出来的路径
            path: /data-nfs

部署

kubectl apply -f nfs-provisioner.yaml -n nfs

部署storageclass—nfs-storageclass.yaml

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  #创建PVC时会用到的参数
  name: nfs-one
  labels:
    uds.dce.daocloud.io/storage-type: file
  annotations:
   # 设置该storageclass为PVC创建时默认使用的存储机制；如果不设置该参数，PVC想要使用该storageclass时需要指定 storageclassname
    storageclass.kubernetes.io/is-default-class: "true" 
#！！！修改值---匹配deployment中的环境变量'PROVISIONER_NAME'
provisioner: nfsone
parameters:
  archiveOnDelete: "true" # "false" 删除PVC时不会保留数据，"true"将保留PVC数据
reclaimPolicy: Retain

部署

kubectl apply -f nfs-storageclass.yaml -n nfs

pvc使用该storageclass

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: hello-pvc
spec:
  storageClassName: nfs-one
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

5、查看是否绑定

kubectl get pvc
