- Kubernetes storage components such as PV and PVC are connected based on two parameters Persistent volume claim name and Persistent Volume name. - PVC contains the volume name which is, PV name itself. Hence, we can show edge for PVC and PV. - This will bring higher level visibility for kubernetes storage components. Signed-off-by: Satyam Zode <satyam.zode@openebs.io>
