      Access Mode	The access mode of the PVC. Default value: ReadWriteMany. You can also select ReadWriteOnce or ReadOnlyMany.	ReadWriteMany

4. Mount the PVC to the application.

   Mount the NAS file system created by using CNFS to the /data path in the container.

   

Use kubectl

Use CNFS to configure an existing NAS file system and use a statically or dynamically provisioned NAS volume to mount the existing NAS file system. Then, mount the statically or dynamically provisioned NAS volume to a Deployment.

1. Create a CNFS file system by using an existing NAS file system.

   1. Use the following template to create a CNFS file system by using an existing NAS file system:

      # Load the existing NAS file system. 
      cat <<EOF | kubectl apply -f -
      apiVersion: storage.alibabacloud.com/v1beta1
      kind: ContainerNetworkFileSystem
      metadata:
        name: cnfs-nas-filesystem
      spec:
        description: "cnfs"
        type: nas
        reclaimPolicy: Retain
        parameters:
          server: 17f7e4****-h****.cn-beijing.nas.aliyuncs.com
      EOF

      Parameter	Description
      description	The description of the file system.
      type	The type of the volume that you want to create.
      reclaimPolicy	The reclaim policy of the NAS file system. Only the Retain policy is supported. If the CNFS file system is deleted, the related NAS file system is retained.
      parameters.server	The URL of the mount target of the NAS file system.

   2. Run the following command to query the NAS file system:

      kubectl get cnfs

      Expected output:

      NAME                  AGE
      cnfs-nas-filesystem   6d

   3. Run the following command to query the details about the NAS file system:

      kubectl get cnfs/cnfs-nas-filesystem -o yaml

      Expected output:

2. Use CNFS to create a NAS volume. For more information, see Step 2 to Step 4 in Method 2: Use CNFS to create a custom NAS file system.

Use the console

1. Create a CNFS file system.

   1. Log on to the ACK console. In the left-side navigation pane, click Clusters.

   2. On the Clusters page, click the name of the cluster that you want to manage. In the left-side navigation pane, choose Volumes > Container Network File System (CNFS).

   3. On the Container Network File System (CNFS) page, click Create CNFS File System.

   4. In the Create CNFS File System panel, configure the parameters and click OK.
