I have a kubernetes cluster in AWS with ec2 worker nodes in the following AZs along with corresponding PersistentVolumes in each AZ.
us-west-2a
us-west-2b
us-west-2c
us-west-2d
My problem is I want to create a Deployment with a volume mount that references a PersistentVolumeClaim and guarantee they land in the same AZ because right now it is luck whether both the Deployment and PersistentVolumeClaim end up in the same AZ. If they don't land in the same AZ then the deployment fails to find the volume mount.
I create 4 PersistentVolumes by manually creates EBS volumes in each AZ and copying the ID to the spec.

I create the PersistentVolumeClaim first and the Deployment does get consistently scheduled in the same AZ.
