I have a cluster on GKE with many pods and persistent disks (PD) and cannot deploy anymore.

pod failed to fit in any node fit failure on node (XX): MaxVolumeCount

The issue should not affect me because I have a 2-code machine and Google recently raised the persistent disk limit to 64:

The problems seems to be a env var in the master that says KUBE_MAX_PD_VOLS = 16. The issue seems to be fixed but since I have a hosted master I cannot find the way to change the env var.

So the question is:

How can I change an env var in a GKE master?

  • I saw the discussion was carry out also here and there has been some progress but not an ideal solution yet.

Google Container Engine is a managed environment so it won't allow you to set env vars on the master.

Options to move this forward will be:

  • Run your own Kubernetes cluster on GCE instead of GKE.
  • Submit a feature request to GKE to provide this feature under 'Container Engine' component.
  • The Issue that you posted is still open, so you might wait for a complete solution.
