Display Storage Classes in a vSphere Namespace

After a vSphere administrator creates a storage policy and assigns it to the vSphere Namespace in vSphere with Tanzu, the storage policy appears as a matching Kubernetes storage class in the vSphere Namespace. It is also replicated to any available Tanzu Kubernetes Grid cluster. As a DevOps engineer, you can verify that the storage class is available.

Your ability to run the commands depends on your permissions.

Prerequisites

Make sure that your vSphere administrator has created an appropriate storage policy and assigned the policy to the vSphere Namespace.

Procedure

Use one of the following commands to verify that the storage classes are available.

kubectl get storageclass

Note: This command is available only to a user with administrator privileges.
You get the output similar to the following. The name of the storage class matches the name of the storage policy on the vSphere side.
```
NAME     PROVISIONER               AGE
silver   csi.vsphere.vmware.com    2d 
gold     csi.vsphere.vmware.com    1d
```

kubectl describe namespace namespace_name

In the output, the name of the storage class appears as a part of the storageclass_name.storageclass.storage.k8s.io/requests.storage parameter. For example:

–––––––––––––––––
Name:                                                            namespace_name
 Resource                                                         Used  Hard
 --------                                                         ---   ---
 silver.storageclass.storage.k8s.io/requests.storage              1Gi   9223372036854775807
 gold.storageclass.storage.k8s.io/requests.storage                0     9223372036854775807

To check the amount of storage space available on the namespace, run the following command.
kubectl describe resourcequotas -namespace namespace
You get the output similar to the following.
```
Name:             ns-my-namespace
Namespace:        ns-my-namespace
Resource          Used  Hard
--------          ----  ----
requests.storage  0     200Gi
```
