使用示例架構：

說明：

nfs默認不支持動態(tài)存儲，使用了第三方的NFS插件
項目插件地址：https://github.com/kubernetes-incubator/external-storage/tree/master/nfs-client/deploy

部署nfs StorageClass：

• clone項目

git clone https://github.com/kubernetes-incubator/external-storage.git
cd external-storage/nfs-client/deploy

• 部署rbac:

kubectl apply -f rbac.yaml

• 部署nfs clinet插件
  注意，deployment.yaml里面的image默認是國外，需要改為自己鏡像倉庫，
  下面的需要改為自己的nfs信息

          env:
            - name: PROVISIONER_NAME
              value: fuseim.pri/ifs
            - name: NFS_SERVER
              value: 10.10.10.60  #NFS地址
            - name: NFS_PATH   #nfs路徑
              value: /ifs/kubernetes
      volumes:
        - name: nfs-client-root
          nfs:
            server: 10.10.10.60   #NFS地址
            path: /ifs/kubernetes   #NFS路徑

kubectl apply -f deployment.yaml
kubectl apply -f class.yaml

• class.yaml文件詳解

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: managed-nfs-storage
provisioner: fuseim.pri/ifs # deployment的env里面的PROVISIONER_NAME的值
parameters:
  archiveOnDelete: "false"

使用：

• 創(chuàng)建pvc

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: test-claim
  annotations:
    volume.beta.kubernetes.io/storage-class: "managed-nfs-storage"  #這里指定的是class.yaml的name
spec:
  accessModes:
    - ReadWriteMany  #運行所有主機讀寫掛載
  resources:
    requests:
      storage: 1Mi  #存儲大小

• pod使用pvc

kind: Pod
apiVersion: v1
metadata:
  name: test-pod
spec:
  containers:
  - name: test-pod
    image: gcr.io/google_containers/busybox:1.24
    command:
      - "/bin/sh"
    args:
      - "-c"
      - "touch /mnt/SUCCESS && exit 0 || exit 1"
    volumeMounts:
      - name: nfs-pvc
        mountPath: "/mnt"
  restartPolicy: "Never"
  volumes:
    - name: nfs-pvc
      persistentVolumeClaim:
        claimName: test-claim  #pvc名字
