Promote CSIPersistentVolume feature to GA #69929

jsafrane · 2018-10-17T12:26:31Z

What this PR does / why we need it:
We want CSIPersistentVolume GA in 1.13, kubernetes/enhancements#178

/milestone 1.13

CSI has many sub-features, this is only about the PersistentVolume part we consider stable enough. Inline volumes and block volumes and similar features have / will have their own alpha features and are / will be tracked separately.

Special notes for your reviewer:
Originally, I filled separate PRs for individual commits here, now I open this PR with everything on one place.

Release note:

CSIPersistentVolume feature, i.e. PersistentVolumes with CSIPersistentVolumeSource, is GA. 
CSIPersistentVolume feature gate is now deprecated and will be removed according to deprecation policy.

We should wait until we get the CSI 1.0 spec changes approved and merged before moving the feature to GA.

same comment about only adding this validation in volumeAttachmentStrategy#Validate, and only when the api request is not coming from the v1beta1 API

I think this was fixed by commit below.

does this have the same issue where you can't delete the Pod object after downgrading to a version where the feature is disabled?

well, not the pod, since this is in PV, but the same issue, yes

pushed a commit to https://github.com/liggitt/kubernetes/commits/csi-ga to resolve this field for this object. I think that looks like what we'll want to do more broadly (consider the existing field on update, and not block in validation based on feature enablement, since it can break update/delete scenarios)

thanks. I will pull your commit and update this branch.
