Hello @haircommander 👋, 1.28 Enhancements team here.

Just checking in as we approach enhancements freeze on 1:00 UTC on Friday 16th June 2023.

This enhancement is targeting 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 need to take care of:

• Merging KEP update PR
• The KEP number seems to be incorrect ie., should this be 3983 instead of 3893?

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 @ruheenaansari34 , I've updated the ID, thanks for pointing that out!

Is there anything else needed at the moment other than getting consensus to merge the enhancement?

[ruheenaansari34]

@yuqi-zhang Please take care of the following before the Enhancement freeze to meet the requirements:

• The status in the kep.yaml should be implementable here - https://github.com/kubernetes/enhancements/blob/8e75faa941843f52b2fb15cbd5eec3ef5edd810e/keps/sig-node/3983-drop-in-configuration/kep.yaml#L7
• Merging KEP update PR

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

[yuqi-zhang]
