I think we're open to adding this feature, but need someone to drive it forward.

[ritazh]

@palnabarun Are you able to drive this KEP for 1.25?

[palnabarun]

@ritazh -- yes, I am going to drive this in 1.25.

Hello @palnabarun 👋, 1.25 Enhancements team here.

Just checking in as we approach enhancements freeze on 18:00 PST on Thursday June 23, 2022.

For note, This enhancement is targeting for stage alpha for 1.25 (correct me, if otherwise)

Here's where this enhancement currently stands:

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

Looks like for this one, we would need to update the above mentioned list items before enhancements freeze and update the test plan in the KEP README.md in the PR according to the latest changes in the proposal template incase you wish to add any more information to that section.

For note, 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 @parul5sahoo, the KEP PR (#3376) under discussion has been filed with the latest template, has test plans, graduation criteria and a production readiness review is under progress.

[Priyankasaggu11929]

Just for record & to keep the history intact. (While deleting one of my own), I ended up deleting one of the bot comments by mistake. 😓

The deleted bot comment read following:

@Priyankasaggu11929: The provided milestone is not valid for this repository. Milestones in this repository: [keps-beta, keps-ga, v1.17, v1.18, v1.19, v1.20, v1.21, v1.22, v1.23, v1.24, v1.25, v1.26]

Use /milestone clear to clear the milestone.

In response to this:

/milestone v.125

[jpbetz]

PRR reviewer here, is there a KEP PR to update this enhancement for Beta? Would someone link to it from this issue's description?

[enj]

@jpbetz #4456 is open.

[jpbetz]

I threw a comment on #4456 but it got missed. Can we get a separate PR to add me as PRR approver for beta in https://github.com/kubernetes/enhancements/blob/master/keps/prod-readiness/sig-auth/3221.yaml?

[liggitt]

@jpbetz #4485 open as a follow up

Hello @palnabarun 👋, Enhancements team here.

Just checking in as we approach enhancements freeze on 02:00 UTC Friday 9th February 2024.

This enhancement is targeting for stage beta forv1.30 (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: v1.30. KEPs targeting stable will need to be marked as implemented after code PRs are merged and the feature gates are removed.
• KEP readme has up-to-date graduation criteria
• KEP has a production readiness review that has been completed and merged into k/enhancements. (For more information on the PRR process, check here).

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

• Waiting for the latest PRR and KEP Template update to get approved and merged: KEP-3221: Add PRR, update metrics #4485

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!

[liggitt]

@AnaMMedina21 I think #4485 is the PR you're looking for to get this KEP in shape for beta (the one you linked is for KEP-3331, not this one). I think I updated to the latest KEP template and answered the new PRR question in that pull request, can you verify that? That PR also adds the beta PRR review record for @jpbetz to complete

[AnaMMedina21]

@liggitt ah, yes, thanks for that correction! sorry about that.
I will update my comment above to reflect this

[liggitt]

#4485 is merged, I think we're set for enhancements freeze
