(kubectl) Creating a Deployment Mounted with an SFS Turbo Volume

Scenario

After an SFS Turbo 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 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

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 efs-deployment-example.yaml file, which is used to create a Deployment:

   touch efs-deployment-example.yaml

   vi efs-deployment-example.yaml

   Example of mounting an SFS Turbo volume to a Deployment (PVC-based, shared volume):

   apiVersion: apps/v1  
   kind: Deployment  
   metadata:  
     name: efs-deployment-example                                # Workload name
     namespace: default  
   spec:  
     replicas: 1  
     selector:  
       matchLabels:  
         app: efs-deployment-example  
     template:  
       metadata:  
         labels:  
           app: efs-deployment-example  
       spec:  
         containers:  
         - image: nginx  
           name: container-0  
           volumeMounts:  
           - mountPath: /tmp                                # Mount path
             name: pvc-efs-example  
         restartPolicy: Always
         imagePullSecrets:
           - name: default-secret
         volumes:  
         - name: pvc-efs-example  
           persistentVolumeClaim:  
             claimName: pvc-sfs-auto-example                # PVC name

   Table 1 Key parameters

   Parameter	Description
   name	Name of the created Deployment.
   app	Name of the application running in the Deployment.
   mountPath	Mount path in the container. In this example, the mount path is /tmp.

   

   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 pod:

   kubectl create -f efs-deployment-example.yaml

   After the creation is complete, choose Storage > SFS Turbo on the CCE console and click the PVC name. On the PVC details page, you can view the binding relationship between SFS Turbo and PVC.
