4.11.2.2. Dynamically provisioning VMware vSphere volumes using the CLI

OpenShift Container Platform installs a default StorageClass, named thin, that uses the thin disk format for provisioning volumes.

Prerequisites

Storage must exist in the underlying infrastructure before it can be mounted as a volume in OpenShift Container Platform.

Procedure (CLI)

You can define a VMware vSphere PersistentVolumeClaim by creating a file, pvc.yaml, with the following contents:
```
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: pvc 
```
1
```
spec:
  accessModes:
  - ReadWriteOnce 
```
2
```
  resources:
    requests:
      storage: 1Gi 
```
3
1
A unique name that represents the persistent volume claim.
2
The access mode of the persistent volume claim. With ReadWriteOnce, the volume can be mounted with read and write permissions by a single node.
3
The size of the persistent volume claim.
Enter the following command to create the PersistentVolumeClaim object from the file:
```
$ oc create -f pvc.yaml
```
