Hello @harche 👋, 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:

• [X] KEP file using the latest template has been merged into the k/enhancements repo.
• [X] KEP status is marked as implementable
• [X] KEP has a updated detailed test plan section filled out
• [X] KEP has up to date graduation criteria
• [X] 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 following:

• update the kep.yaml file in the merged KEP to add latest-milestone: "v1.25”

For note, the status of this enhancement is marked as at risk. Thank you for keeping the issue description up-to-date!

Hello @harche ! 👋🏾,

@katmutua 1.26 Release Docs shadow here. This enhancement is marked as ‘Needs Docs’ for 1.26 release.

Please follow the steps detailed in the documentation to open a PR against dev-1.26 branch in the k/website repo. This PR can be just a placeholder at this time, and must be created by November 9.

Also, take a look at Documenting for a release to familiarize yourself with the docs requirement for the release. As a reminder, please link all of your docs PR to this issue so we can easily track it.

[harche]

@katmutua Considering this feature is just alpha, I am not sure if we need to have docs.

cc @haircommander @ruiwen-zhao

[krol3]

Hi @harche , here Carol from the Doc Lead of 1.26, I think we need to update the Kubernetes documentation features with alpha, for example here cc @reylejano

[reylejano]

@harche , For 1.26, since this enhancement has a feature gate of EventedPLEG, this should be added to the feature gates page in the Feature gates for Alpha or Beta features table: https://kubernetes.io/docs/reference/command-line-tools-reference/feature-gates/#feature-gates-for-alpha-or-beta-features

[harche]

Thanks @katmutua @krol3 and @reylejano. I have created a doc PR https://github.com/kubernetes/website/pull/37715 to add EventedPLEG in the features table.

Hey @harche @ruiwen-zhao @haircommander 👋, just a quick check-in again before 1.26 code freeze at 17:00 PDT Tuesday 8th November 2022 i.e tomorrow. Looks like we would at least need to get the code PR/s: https://github.com/kubernetes/kubernetes/pull/111384 (any other PRs?) merged before the code-freeze.

[rhockenbury]

With https://github.com/kubernetes/kubernetes/pull/111384 merged, we have this marked as tracked for code freeze.

[harche]

Hey @harche @ruiwen-zhao @haircommander wave, just a quick check-in again before 1.26 code freeze at 17:00 PDT Tuesday 8th November 2022 i.e tomorrow. Looks like we would at least need to get the code PR/s: kubernetes/kubernetes#111384 (any other PRs?) merged before the code-freeze.
