@andrewsykim Based on the discussion it looks like you are still planning this for 1.19? If so I will make sure we track it in the release team.

@andrewsykim Based on the discussion it looks like you are still planning this for 1.19? If so I will make sure we track it in the release team.

I know there's a lot of other efforts in-flight in SIG Network so no worries if this slips v1.19. Assuming we're happy with what's proposed, I intend to work on this for v1.19

[johnbelamaric]

We are trying to reduce content and risk in v1.19 so if you can defer to v1.20 that would be best.

[johnbelamaric]

@andrewsykim Hi Andrew, tomorrow is Enhancements Freeze for 1.19, what's the decision? 1.19 or 1.20?

[andrewsykim]

Happy to work on this for v1.19, KEP just needs approval/review at this point. If it slips to v1.20 that is okay with me as well :).

[johnbelamaric]

Enhancements freeze is upon us, deferring to 1.20.

Hi @andrewsykim

Enhancements Lead here, do you still intend to target this for GA in 1.20?

Thanks!
Kirsten

[kikisdeliveryservice]

Hi @andrewsykim

Pinging again, is this to be included in 1.20?

Thanks
Kirsten

[kikisdeliveryservice]

Hi @andrewsykim @thockin

Another reminder: Enhancements Freeze is next Tuesday October 6th. If you intend for this enhancement to be included, please let me know. This KEP's graduation criteria says it's dependent on #1672 , but #1672 currently does not have any KEP associated with it. So if this were to proceed into 1.20, you would need to update the graduation criteria.

I also note that this KEP seems to be missing the PRR.

Thanks,
Kirsten

[andrewsykim]

Sorry @kikisdeliveryservice this KEP was merged in v1.19, forgot to update the description with a link

[kikisdeliveryservice]

Hi @andrewsykim

Thanks for the update. A little confusion bc the graduation criteria says:

The graduation criteria of this KEP will largely depend on the graduation status of the EndpointSlice API. Once the terminating field is added to EndpointSlice API, this change in behavior will kick-in as soon as kube-proxy consumes EndpointSlice.

Is that correct? What do you expect to delivery in this release exactly? Can you update the KEP to provide some clarity?

Thanks!
Kirsten

[kikisdeliveryservice]

@andrewsykim

As a reminder Enhancements Freeze is October 6th, so you will need to update your KEP by that time to lay out the alpha (this release deliverable), alpha->beta, etc... graduation criteria as requested above.

Thanks!
Kirsten

[andrewsykim]

Updated alpha graduation criteria here #2064

[kikisdeliveryservice]

@andrewsykim This is great and much clearer!! 👍

[kikisdeliveryservice]

Hi @andrewsykim

Ping!

As a reminder your PR (#2064 ) needs to merge by EOD PST tomorrow October 6th to be included in the 1.20 Release. After that time you will need to request an exception.

Best,
Kirsten

[kikisdeliveryservice]

#2064 merged! Updating tracking sheet now. 😄

[kikisdeliveryservice]

Hey @andrewsykim 👋 Enhancements Lead here,
With kubernetes/kubernetes#117718 merged as per the issue description, this enhancement is now tracked for v1.28 Code Freeze. Thanks!

[Rishit-dagli]

Hey @andrewsykim , I apologize for the ping again but we are already past the deadline for having a draft docs PR make on kubernetes/website , could you please do this as soon as possible, it could be a PR with no content yet too.

[VibhorChinda]

Hello @andrewsykim 👋 please take a look at Documenting for a release - PR Ready for Review to get your PR ready for review before Tuesday 25th July 2023. Thank you!

[Rishit-dagli]

Hey @kubernetes/sig-network-leads (sorry for another ping after https://kubernetes.slack.com/archives/C09QYUH5W/p1689977384967339),

I'm Rishit from the 1.28 Release Team. We had this KEP which is past the deadline for having a draft documentation PR for the 1.28 release. As indicated here the deadline to create a draft docs PR on kubernetes/website for the KEP was 20th July. Could you please take a look at this and populate the docs PR was 25th July?

[andrewsykim]

Opened a PR to update feature gate reference in kubernetes/website#42229. Other docs were added in previous releases.

[npolshakova]

Hey @andrewsykim 👋 1.29 Enhancements Lead here, is there any more work planned for this KEP? Also is the milestone accurate (are you targeting v1.30 instead of v1.29?)

[npolshakova]

/remove-label lead-opted-in

[aojea]

This KEP is finished, last step is to completely remove the feature tag from the code, that is why it targets 2 releases after GA
