How do i auto delete persistence disks attached to my instances?

[uvi...@anutanetworks.com]

I have a kubernetes cluster with dynamic persistence volume attached using pd-ssd

Everything works fine but when i delete the cluster, I don't see the dynamically created the pvc or persistence disks being deleted. Is there any flag i can set in storage class or pv claim section?

On searching i did see a flag "Keep disk" at instance level. And similar flag in gcloud compute instances set-disk-auto-delete sdk page. Is this the only way for my case?

Please suggest if there is any flag which can be controlled during cluster creation/node pool addition.


PS: retain policy in storage class is set to delete as well.

I am able to reproduce your issue. I have already informed our GKE team to investigate the issue further.

By the time being a workaround is to avoid the issue is to delete the claim corresponding PersistentVolume object and it will also delete the provisioned Compute Engine persistent disk [1], before you delete the cluster.
