Volumes

This example illustrates how a Workload can use persistent storage service through the Kubernetes volumes system. It uses the volume-pvc Driver to create a PersistentVolume for your application. If you have special requirements for your PersistentVolume, you can also use the Template Driver to create it as shown in this other example.
