@MrHohn the feature is still labeled as alpha, but your plans for 1.10 were beta. What is the actual status of the feature for 1.10?

MrHohn · 2018-01-29T17:50:20Z

@idvoretskyi Thanks for checking in. This feature is targeting beta for 1.10.

/stage beta

MrHohn · 2018-01-29T17:51:36Z

Seems like I don't have the label privilege though. @idvoretskyi Would be great to use your help :)

MrHohn · 2019-01-23T22:57:28Z

@claurence Thanks for handling the milestone and labels. To confirm, we need to merge the KEP PR (#700) before the Enhancements freeze, right?

claurence · 2019-01-24T14:54:16Z

@MrHohn we'd like the KEP in an implementable state by enhancements freeze.

claurence · 2019-02-11T17:06:33Z

@MrHohn Hello - enhancements lead here - looking at the KEP it is still marked as "provisional". What more is needed for it to move to "implementable"

Additionally are there any open PRs that should be tracked for this issue for the 1.14 release?

MrHohn · 2019-02-11T17:50:51Z

@claurence Thanks for checking in. The KEP should be implementable --- I will update that.

One more open PR is kubernetes/website#12514 for the doc change.

liggitt · 2019-02-15T04:59:16Z

kubernetes/kubernetes#72832 merged, no visible API changes

claurence · 2019-02-22T21:27:22Z

@MrHohn looking over the KEP I don't see any testing plans - can someone help PR in testing plans for this enhancement? This information is helpful for knowing readiness of this feature for the release and is specifically useful for CI Signal.

If we don't have testing plans this enhancement will be at risk for being included in the 1.14 release

MrHohn · 2019-02-22T21:34:30Z

@claurence We have comprehensive e2e tests implemented a while back, and that task was tracked by kubernetes/kubernetes#56521. I can retrospectively add testing plans to the KEP if that is preferable.

claurence · 2019-02-22T21:40:37Z

@MrHohn if you can add them to the KEP that would be great!

lledru · 2019-02-25T15:14:30Z

Hello @MrHohn , 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

MrHohn · 2019-02-26T01:26:15Z

@lledru Thanks for checking in. There is no open K/K PRs that need to merge. (I do need to send a PR to add testing plans to KEP but that is not K/K.)

lledru · 2019-03-03T19:52:00Z

Hi @MrHohn, when do you think you could merge PR #867 ? Just checked with my enhancement teammates, this information is helpful for knowing readiness of this feature for the release and is specifically useful for CI Signal.
If we don't have testing plans this enhancement will be at risk for being included in the 1.14 release. Best regards

MrHohn · 2019-03-03T19:58:38Z

@lledru We will make sure to get that in before 1.14 code freeze (hopefully next Monday-ish).
