在k8s集群中利用NFS服务建立storageclass动态存储

查看storage-class.yaml文件；

apiVersion: storage.k8s.io/v1beta1
kind: StorageClass
metadata:
  name: managed-nfs-storage
provisioner: fuseim.pri/ifs

apiVersion: v1

kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1

  - apiGroups: [""]
    resources: ["persistentvolumes"]
    verbs: ["get", "list", "watch", "create", "delete"]
  - apiGroups: [""]

          volumeMounts:

              mountPath: /persistentvolumes
          env:
            - name: PROVISIONER_NAME
              value: fuseim.pri/ifs
            - name: NFS_SERVER
              value: 172.18.128.141   #你的nfs服务
            - name: NFS_PATH
              value: /data/nfs   #对应在/etc/exports的路径
      volumes:
        - name: nfs-client-root
          nfs:
            server: 172.18.128.141
            path: /data/nfs

执行：

kubectl apply -f storage-class.yaml

创建pvc请求检测；

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mypvc
spec:
  accessModes: ["ReadWriteMany"] #
  resources:
    requests:
      storage: 1Gi
  storageClassName: managed-nfs-storage

 kubectl apply -f pvc-nfs-storageclass.yaml 

pvc与storageclass自动创建的pv绑定，storageclass成功使用。
