Exception request: Pod Priority Based Node Graceful Shutdown

[David Porter]

Hello,

We are requesting an exception for a k8s 1.23 enhancement.

Enhancement name: Pod Priority Based Node Graceful Shutdown

Enhancement status (alpha/beta/stable): alpha

SIG: node

k/enhancements repo issue: #2712

PR #’s: https://github.com/kubernetes/kubernetes/pull/102915

Additional time needed (in days): 3

The main reason we need additional time is because there are some very minor API documentation only changes that need to be made and due to time zone difference between the contributor (China) and API reviewers (US) we are concerned that there will not be enough time to make the changes by the upcoming code freeze. An additional three days will ensure there is enough slack time to address these minor API documentation updates in spite of time zone differences.   

Reason this enhancement is critical for this milestone: Makes the node graceful shutdown feature priority class value based and more useful to deploy in production.

Risks from adding code late: (to k8s stability, testing, etc.) Risk is very low since this is alpha and feature gated, and in addition it adds a set of new unit and integration tests.

Risks from cutting enhancement: (partial implementation, critical customer use case, etc.): 

Slower path to graduation as this helps ensure correct node behavior at shutdown/reboot time. This enchantment was originally targeted for 1.22 release, and we would like to ensure we can get it in for 1.23. 

Thanks in advance for your consideration,

David
