Hello @zylxjtu 👋, v1.32 Enhancements team here.

Just checking in as we approach enhancements freeze on 02:00 UTC Friday 11th October 2024 / 19:00 PDT Thursday 10th October 2024.

This enhancement is targeting for stage alpha for v1.32 (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.
• [x] KEP status is marked as implementable for latest-milestone: v1.32.
• [x] KEP readme has up-to-date graduation criteria
• [x] KEP has a production readiness review that has been completed and merged into k/enhancements. (For more information on the PRR process, check here). If your production readiness review is not completed yet, please make sure to fill the production readiness questionnaire in your KEP by the PRR Freeze deadline on Thursday 3rd October 2024 so that the PRR team has enough time to review your KEP.

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

• [x] Create the KEP readme using the latest template and merge it in the k/enhancements repo. KEP's README.md file is missing few checkboxes under the "Release Signoff Checklist" need to be added here to conform to the latest KEP template.

• [x] Ensure that the KEP has undergone a production readiness review and has been merged into k/enhancements.

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

If you anticipate missing enhancements freeze, you can file an exception request in advance. Thank you!

just a nit. since this is an implementation of a comparable feature to GracefulNodeShutdown (https://github.com/kubernetes/enhancements/tree/master/keps/sig-node/2000-graceful-node-shutdown ) , maybe changing the order of the words in the title to reflect its relation would improve this feature's consistency, searchability, and referencing. Unless, maybe it was intentionally worded this way to make sure "windows" and "node" are directly connected.

@zylxjtu With PR https://github.com/kubernetes/enhancements/pull/4813 has been merged, almost all the KEP requirements are in place. It looks like this KEP's README.md file is missing few checkboxes under the "Release Signoff Checklist" need to be added here to confrom to the latest KEP template.

Below is the reference from the KEP template.

https://github.com/kubernetes/enhancements/blob/c42bf65391179148004e616fc1f44f0d2d098c43/keps/NNNN-kep-template/README.md?plain=1#L134-L139

Hey again @zylxjtu 👋 v1.32 Enhancements team here,

• [ ] All PR/s are ready to be merged (they have approved and lgtm labels applied) by the code freeze deadline. This includes tests.

For this enhancement, it looks like the following PRs are open and need to be merged before code freeze (and we need to update the Issue description to include all the related PRs of this KEP):

• https://github.com/kubernetes/kubernetes/pull/127404

Additionally, please let me know if there are any other PRs in k/k not listed in the description or not linked with this GitHub issue that we should track for this KEP, so that we can maintain accurate status.

If you anticipate missing code freeze, you can file an exception request in advance. Thank you!

Hello @zylxjtu,

Please let us know if you still have cycles to work on this for 1.32. We would need a website update as mentioned above.

I also would like to understand if https://github.com/kubernetes/kubernetes/pull/116388 is an implementation of this feature. That reads like an old refactor PR and not the implementation of the KEP.

So please get back to us or we will consider this feature to no longer be tracked for release.

[zylxjtu]

I have added a draft PR for the doc in here: https://github.com/kubernetes/website/pull/48474, please let me know if I am still missing anything, thanks!

The https://github.com/kubernetes/kubernetes/pull/116388 is unrelated with the is feature, the corresponding code PR for this KEP is https://github.com/kubernetes/kubernetes/pull/127404

[dipesh-rawat]

@zylxjtu Could you please add the code PR(s) https://github.com/kubernetes/kubernetes/pull/127404 (any other related PRs in k/k also remove unrelated PRs) in the description (here), so that we can maintain accurate status.

[zylxjtu]
