Hello @derekwaynecarr, 1.14 enhancement shadow here. Code Freeze is March 7th and all PRs must be merged by then to your issue to make the 1.14 release. What open K/K PRs do you still have that need to merge? Thanks

Hey @derekwaynecarr. Just a friendly reminder we're looking for a PR against k/website (branch dev-1.14) due by Friday, March 1. It would be great if it's the start of the full documentation, but even a placeholder PR is acceptable. Let me know if you have any questions!

kubernetes/kubernetes#73651 implements node-to-pid isolation for 1.14.
@RobertKrawitz could you open a PR against kubernetes/website for documenting this. Doesn't have to be the full thing yet. I think @simplytunde just needs the PR for release tracking atm.

kubernetes/website#12932 is a placeholder.

Above PR is complete and waiting for review/approval.

kubernetes/website#13006 as well

Hey @derekwaynecarr @sjenning

Is kubernetes/kubernetes#94140 the only k/k pr required to move this to GA? Is all work done? Code freeze is tomorrow.

Thanks
Kirsten

Confirmed with both Derek and Seth that this is completed. 👍

Just a quick check that in the process of promoting this feature to GA, was there any change to the API surface area?

Particularly swagger.json?

We have a process for detecting new GA API operations, but it currently looks primarily at the generated OpenAPI spec.

it tests only GA, non-optional features or APIs (e.g., no alpha or beta endpoints, no feature flags required, no deprecated features)

^ From: https://github.com/kubernetes/community/blob/master/contributors/devel/sig-architecture/conformance-tests.md#conformance-test-requirements

@dims Can I get your check-in on this? It doesn't seem to touch the OpenAPI spec, but if looks non-optional:

https://github.com/kubernetes/kubernetes/pull/94140/files#diff-71e3b98f9a6bbf5b8421e26a7ba0c079f397cd8d49abacdad943c66a4f44f03dR685-R686

+ SupportPodPidsLimit: {Default: true, PreRelease: featuregate.GA, LockToDefault: true}, // remove in 1.21
+ SupportNodePidsLimit:{Default: true, PreRelease: featuregate.GA, LockToDefault: true}, // remove in 1.21

There is no end user api change in the promotion. The feature has been on by default via kubelet Config for multiple releases.

Thanks @derekwaynecarr !

@derekwaynecarr I wonder if the pid limit test should have been promoted to conformance as part of the GA process? It seems to be satisfying all requirements. I understand now there is a validation for the APIs to be conformance tested. I also see conformance tests for things like config maps. I wonder whether graduation criteria in general should include promoting a test to conformance whenever possible.

On KEP I see the graduation criteria that doesn't say anything about conformance tests:

GA

• assuming no negative user feedback, promote after 1 release at beta.

The only note on desire to increase coverage of conformance tests I found here:

NB: This should be viewed as a living document in a few key areas:

The desired set of conformant behaviors is not adequately expressed by the current set of e2e tests, as such this document is currently intended to guide us in the addition of new e2e tests than can fill this gap

Hi @SergeyKanzhelev @derekwaynecarr, 1.21 Enhancement Lead here.
Does this issue need to be kept open?

This is GA'd. I don't see the reason to keep it open. @annajung can you please fix the link to KEP text in this issue description?

Great, it's been fixed.
With it being GA and KEP updated to implemented, I'm closing this issue.
