Description
Currently our CSI Pod cant be scheduled in certain scenarios, because of lacking resources on the cluster. However if the customer uses a deployment mode, which relies on the CSI Driver Pod to be there and handle volumes, it then leads to the situation that every pod gets the CSI Volume added by the webhook, but the CSI Pod can not handle those requests because he is simply not there. In consequence the application pod, which gets the CSI Volume cannot start and will fail.
Therefor I added a new priorityClass, which is set to a high priority by default, in order to make sure our CSI Pods can be scheduled
How can this be tested?
