Hey there @davidz627 / @jsafrane -- 1.19 Enhancements shadow here. I wanted to check in and see if you think this Enhancement will be graduating in 1.19?

In order to have this part of the release:

1. The KEP PR must be merged in an implementable state
2. The KEP must have test plans
3. The KEP must have graduation criteria.

The current release schedule is:

• Monday, April 13: Week 1 - Release cycle begins
• Tuesday, May 19: Week 6 - Enhancements Freeze
• Thursday, June 25: Week 11 - Code Freeze
• Thursday, July 9: Week 14 - Docs must be completed and reviewed
• Tuesday, August 4: Week 17 - Kubernetes v1.19.0 released

If you do, I'll add it to the 1.19 tracking sheet (http://bit.ly/k8s-1-19-enhancements). Once coding begins please list all relevant k/k PRs in this issue so they can be tracked properly. 👍

Thanks!

Hey @jsafrane / @davidz627, I'm following up on my previous update on this Enhancement being part of the v1.19 release.

Do you happen to have any update on the possiblity of this being included in the release v1.19?

Thanks again for your time and contributions. 🖖

Hey @jsafrane / @davidz627, any plans for the Enhancements to be included in v1.19? Please let me know so that I can update the tracking sheet to show the inclusion state.

Enhancements freeze is on May 19

Note that recently the KEP format has changed. Additionally, #1620 merged recently, adding production readiness review questions to the KEP template. Please take this opportunity to reformat your KEP and also answer the questions added to the template in that PR.

Thanks, 🖖

[jsafrane]

No, we're going to skip GA in 1.19.

[leakingtapan]

Skipping 1.19 sounds reasonable to me

[harshanarayana]

Hey @jsafrane @leakingtapan Thanks for the confirmation. I've updated the trackers accordingly.

Hi @jsafrane

Enhancements Lead here. Any plans for this in 1.20?

Thanks! Kirsten

[kikisdeliveryservice]

No, we're going to skip GA in 1.19.

Hi @jsafrane @leakingtapan

I'm a bit confused with the state of this KEP. Can you please update with the status? Should it be marked implemented and the issue closed? The linked KEP doesn't indicate that it was finished and there are no PRs linked to this issue.

Enhancements Freeze is October 6th, if we could sort this out soon, that would be great.

As a note, the format of KEPs has changed as mentioned above. If you could please update and include the missing sections noted above that would be great. See for ref https://github.com/kubernetes/enhancements/tree/master/keps/NNNN-kep-template

Best, Kirsten

Hi, this is the kep: https://github.com/kubernetes/enhancements/blob/master/keps/sig-storage/20190129-csi-migration.md

This feature is still beta, and we don't plan to move it to GA in 1.20

[leakingtapan]

@msau42 is correct. Also we will need a plan to move it to beta on first then consider GA. As the feature is beta off now.

@wongma7 do you plan on enabling by default in 1.21?

[wongma7]

I'll have a definitive answer by end of this week (Feb ~5), not 100% sure just yet.

[wongma7]

We won't be enabling by default in 1.21, are targeting 1.22 instead*.
