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 the workload:

   kubectl create -f sfs-deployment-example.yaml
