先安装alicloud-nas-controller

          env:
          - name: PROVISIONER_NAME
            value: alicloud/nas
          securityContext:
            privileged: true
          volumeMounts:
          - mountPath: /var/log
            name: log
      volumes:
      - hostPath:
          path: /var/log
        name: log

新建nas，过载到ecs，在nas根目录创建子目录如k8s-nas

创建StorageClass

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: nas
mountOptions:
- nolock,tcp,noresvport
- vers=4
parameters:
  server: "test1234-ejs14.cn-hongkong.nas.aliyuncs.com:/k8s-nas"
  driver: flexvolume
provisioner: alicloud/nas
reclaimPolicy: Retain

说明

mountOptions：表示生成的pv options 配置，挂载NAS卷时使用这个options挂载。
server：表示生成目标PV所使用NAS挂载点列表。格式为 nfsurl1:/path1,nfsurl2:/path2；当配置多个server时，通过此storageclass创建的PV会轮询使用上述server作为配置参数；极速NAS配置路径需要以/share开头。
driver：支持Flexvolume、NFS两种驱动，默认为NFS。
reclaimPolicy：PV的回收策略，建议配置为 Retain。
当配置为Delete时，删除PV后NAS文件系统中的对应目录会默认修改名字（例如，path-name会被修改为archived-path-name）。
如果需要删除文件系统中对应的存储目录，可在storageclass中配置archiveOnDelete为false。
