Hello @sunnylovestiramisu 👋, Enhancements team here.

Just checking in as we approach enhancements freeze on 01:00 UTC Friday, 16th June 2023.

This enhancement is targeting for stage alpha for 1.28 (correct me, if otherwise)

Here's where this enhancement currently stands:

• KEP readme using the latest template has been merged into the k/enhancements repo.
• KEP status is marked as implementable for latest-milestone: 1.28
• KEP readme has a updated detailed test plan section filled out
• KEP readme has up to date graduation criteria
• KEP has a production readiness review that has been completed and merged into k/enhancements.

For this KEP, we would just need to update the following:

• Update status to implementable in kep.yaml
• Add the test plan in the readme file
• Address questions inside the Production Readiness Review Questionnaire

The status of this enhancement is marked as at risk. Please keep the issue description up-to-date with appropriate stages as well. Thank you!

Hi @sunnylovestiramisu , Could you update the link of Kubernetes Enhancement Proposal to https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/3751-volume-attributes-class.

The pr link is difficult for users to learn the content of this KEP.

Hi @dipesh-rawat, the following PRs should no longer be tracked for Kubernetes v1.31.

• Add quota support for PVC with VolumeAttributesClass kubernetes#124360
• Add quota support for PVC with VolumeAttributesClass kubernetes#121895

See #4765 for more information!

Also:

• A new controller adds/removes finalizer

Is optional for Kubernetes v1.31. If it gets approved in time, that is great, but it should NOT block enhancement promotion to beta!

We will update issue with correct PRs now. Thank you so much for your help/updates!

[dipesh-rawat]

@AndrewSirenko Thank you for confirming the list of PRs to track for this KEP. I’ve updated the original comment accordingly. I’ll update the status of the KEP on the v1.31 project board closer to the code freeze deadline time later today. Thanks for keeping us informed and ensuring everything is up to date.

[AndrewSirenko]

@dipesh-rawat looks like the final blocking PR is approved by all relevant stakeholders: kubernetes/kubernetes#126145 (comment)

Should merge soon.

Thanks again!

[dipesh-rawat]
