Creating ephemeral volumes

Last published : Jun 12, 2026
Some applications like caching services do not require persistent storage. Ephemeral volumes are temporary volumes which such applications can utilize. You can use InfoScale CSI drivers to create generic ephemeral volumes.
Ephemeral volumes can be created in block mode also by setting volumeMode to 'Block'. Snapshotting, cloning, and resizing are also supported. See the sections above to know more.
Complete the following steps to create ephemeral volumes by using an InfoScale CSI driver storage class.
  1. Copy the following content and save as ephemeral_volume_pod.yaml.
kind: Pod
apiVersion: v1
metadata:
  name: test-pod
spec:
  containers:
    -  name: test-pod-container
      image: busybox
      volumeMounts:
      -  mountPath: "/ephemeral"
        name: ephemeral-volume
      command: [ "sleep", "1000000" ]
  volumes:
    -  name: ephemeral-volume
      ephemeral:
        volumeClaimTemplate:
          metadata:
            labels:
              type: test-pod-volume
          spec:
            accessModes: [ "ReadWriteOnce" ]
            storageClassName: "vxvmsc-mirror"
            resources:
              requests:
                storage: 1Gi
  1. Run the following command to create an application pod with the ephemeral volume.
kubectl/oc apply -f ephemeral_volume_pod.yaml
  1. Run the following command to verify.
kubectl/oc get pvc
