(kubectl) Creating a Deployment Mounted with an SFS Volume

Scenario

After an SFS volume is created or imported to CCE, you can mount the volume to a workload.

Prerequisites

You have created a CCE cluster and installed the CSI plug-in (everest) in the cluster.

Notes and Constraints

The following configuration example applies to clusters of Kubernetes 1.15 or later.

Procedure

  1. Use kubectl to connect to the cluster. For details, see Connecting to a Cluster Using kubectl.
  2. Run the following commands to configure the sfs-deployment-example.yaml file, which is used to create a pod.

    touch sfs-deployment-example.yaml

    vi sfs-deployment-example.yaml

    Example of mounting an SFS volume to a Deployment (PVC-based, shared volume): 
    apiVersion: apps/v1 
kind: Deployment 
metadata: 
  name: sfs-deployment-example                                # Workload name
  namespace: default 
spec: 
  replicas: 1 
  selector: 
    matchLabels: 
      app: sfs-deployment-example 
  template: 
    metadata: 
      labels: 
        app: sfs-deployment-example 
    spec: 
      containers: 
      - image: nginx 
        name: container-0 
        volumeMounts: 
        - mountPath: /tmp                                # Mount path 
          name: pvc-sfs-example 
      imagePullSecrets:
        - name: default-secret
      restartPolicy: Always 
      volumes: 
      - name: pvc-sfs-example 
        persistentVolumeClaim: 
          claimName: pvc-sfs-auto-example                # PVC name

    spec.template.spec.containers.volumeMounts.name and spec.template.spec.volumes.name must be consistent because they have a mapping relationship.

  3. Run the following command to create a pod:

    kubectl create -f sfs-deployment-example.yaml

    After the creation is complete, log in to the CCE console. In the navigation pane, choose Resource Management > Storage > SFS. Then, click the PVC name. On the PVC details page, you can view the binding relationship between SFS and PVC.
