Creating a storage class for vSphere volume

Create a storage class to provide PersistentVolume on a vSphere datastore.

Required user type or access level: Cluster administrator

Prerequisites

IBM® Cloud Private must be configured with a vSphere Cloud Provider. See Configuring a vSphere Cloud Provider.

Create a storage class

To create a storage class for a vSphere volume, specify the following field values in the storage class definition:

• metadata:
  • name: Name of the storage class object.
• parameters:
  • diskformat: thin, zeroedthick, or eagerzeroedthick.
  • datastore: Name of the datastore. The volume is created on the datastore that is specified in the storage class.
  • storagePolicyName: Name of the storage policy that you created in your vSphere setup. A persistent volume (PV) is dynamically provisioned based on the storage policy. For more information about storage policy based management (SPBM), see Storage Policy Based Management for dynamic provisioning of volumes .

Following is an example of how to create a storage class:

1. Create a YAML file with the storage class definitions:

    vim vsphere-volume-storage-class-1.yaml
   

   kind: StorageClass
   apiVersion: storage.k8s.io/v1
   metadata:
    name: storage-class-1
   provisioner: kubernetes.io/vsphere-volume
   parameters:
    diskformat: thin
    datastore: datastore-1
    storagePolicyName: vsanStoragePolicy
   

2. Create the storage class:

    kubectl create -f vsphere-volume-storage-class-1.yaml
   

   The output resembles the following code:

   storageclass "storage-class-1" created
   

3. Verify that the storage class is created:

    kubectl describe sc storage-class-1
   

   The output resembles the following code:

   Name:           storage-class-1
   IsDefaultClass: No
   Annotations:    <none>
   Provisioner:    kubernetes.io/vsphere-volume
   Parameters:     datastore=datastore-1,diskformat=thin,storagePolicyName=vsanStoragePolicy
   Events:         <none>
