(kubectl) Automatically Creating an SFS Volume

Scenario

CCE supports creating SFS volumes through PersistentVolumeClaims (PVCs).

Prerequisites

You have created a CCE cluster and installed the FlexVolume plug-in (storage-driver) in the cluster.

Notes and Constraints

The following configuration example applies to clusters of Kubernetes 1.13 or earlier.

Procedure

Use kubectl to connect to the cluster. For details, see Connecting to a Cluster Using kubectl.

Run the following commands to configure the pvc-sfs-auto-example.yaml file, which is used to create a PVC.

touch pvc-sfs-auto-example.yaml

vi pvc-sfs-auto-example.yaml

Example YAML file:

apiVersion: v1 
kind: PersistentVolumeClaim 
metadata: 
  annotations: 
    volume.beta.kubernetes.io/storage-class: nfs-rw
  name: pvc-sfs-auto-example 
  namespace: default 
spec: 
  accessModes: 
  - ReadWriteMany 
  resources: 
    requests: 
      storage: 10Gi

**Table 1** Key parameters
Parameter	Description
volume.beta.kubernetes.io/storage-class	File storage class. Currently, the standard file protocol type (nfs-rw) is supported.
name	Name of the PVC to be created.
accessModes	Only ReadWriteMany is supported. ReadWriteOnly is not supported.
storage	Storage capacity in the unit of Gi.

Run the following command to create the PVC.
kubectl create -f pvc-sfs-auto-example.yaml

After the command is executed, a file system is created in the VPC to which the cluster belongs. Choose Storage > SFS on the CCE console or log in to the SFS console to view the file system.
