(kubectl) Automatically Creating an SFS Volume

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 Conexión a un clúster con kubectl.
2. 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

   Tabla 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.

3. Run the following command to create a 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.
