Enable ignore-volume-az option #2751

Closed jbcraig closed 6 years ago

jbcraig commented 6 years ago

FEATURE REQUEST?

Allow one to specify an option like openstack_ignore_volume_az in all.yml as true/false. When true include the following stanza in cloud_config:

[BlockStorage]
ignore-volume-az=true

I, like many, use ceph as a backing store for cinder and I have multiple AZz. This causes havoc when creating PVs as they are labeled with the default zone that cinder specifies, in my case "nova". When a pod makes a claim it will fail to match unless you happen to have nodes in the default zone. For ceph backed block storage volumes aren't restricted to a single zone, so this option tells k8s to ignore the cinder zone and not label volumes with an AZ. Then all is good in the k8s PV world.

My bad, now I see that you have the option volume_cross_zone_attachment to solve this same issue. Not sure which approach is best, I was planning to submit a pull request but now I'm not sure whether to proceed.

if this is still actual please reopen issue
