# Provisioning Ephemeral Volumes

VAST CSI Driver supports Ephemeral Volumes (EVs). You can provision PVCs directly from pod definitions, which are discarded once the pod is terminated.

Specify the `volumeAttributes` as follows:

- `root_export`: as in the storage class definition.
- `view_policy`: as in the storage class definition.
- `vip_pool_name`: as in the storage class definition.
- `size`: as in the PVC.

For example:

```plaintext
apiVersion: v1
kind: Pod
metadata:
  name: some-pod
spec:
  containers:
  - command:
    - sh
    - -c
    - while true; do date -Iseconds >> /shared/$HOSTNAME; sleep 1; done
    image: busybox
    name: my-frontend
    volumeMounts:
    - mountPath: /shared
      name: my-eph-vol
  volumes:
  - csi:
      driver: csi.vastdata.com
      volumeAttributes:
        root_export: /k8s
        view_policy: default
        vip_pool_name: vippool-1
        size: 1G
    name: my-eph-vol
```
