@SidakM - Hello I'm the enhancements lead for 1.14. It looks like this issue is targeting 1.14 for alpha can you let me know if that is still planned. Enhancements freeze is Jan 29th and we want all issues to have a KEP associated with them.

SidakM-zz commented 5 years ago

Hey @claurence , Was waiting for a review from @kubernetes/sig-apps-feature-requests . Not sure when one of them will look at it though.

@SidakM checking in as enhancements freeze is on Tuesday - was the KEP reviewed? Are there any open PRs to track for the 1.14 cycle?

SidakM-zz commented 5 years ago

@claurence Someone looked and commented but didn't follow up after so I am unsure where its at.

claurence commented 5 years ago

@SidakM since the KEP for this issue isn't merged yet we will be removing it from the 1.14 milestone. To have it added back in please file an exception - information on the exception process can be found here: https://github.com/kubernetes/sig-release/blob/master/releases/EXCEPTIONS.md

delgod commented 5 years ago

@claurence it is critical functionality for stateful applications like databases. If your run databases - you must to use StatefulSet. so currently, PVC resize feature is mostly useless without StatefulSet resize. please include it to 1.14 milestone.

claurence commented 5 years ago

@delgod because we have passed enhancement freeze and the KEP still is not merged please submit an exception request.

chino commented 5 years ago

Can we see something similar for DaemonSets?

kacole2 commented 5 years ago

I'm the Enhancement Lead for 1.15. Is this feature going to be graduating alpha/beta/stable stages in 1.15? Please let me know so it can be tracked properly and added to the spreadsheet. Enhancements do require a KEP as well.

Once coding begins, please list all relevant k/k PRs in this issue so they can be tracked properly.

SidakM-zz commented 5 years ago

@gnufied Can we get this in for 1.15?

evillgenius75 commented 5 years ago

Hi @SidakM , I'm the 1.16 Enhancement Shadow. Is this feature going to be graduating alpha/beta/stable stages in 1.16? Please let me know so it can be added to the 1.16 Tracking Spreadsheet.

Once coding begins or if it already has, please list all relevant k/k PRs in this issue so they can be tracked properly.

As a reminder, every enhancement requires a KEP in an implementable state with Graduation Criteria explaining each alpha/beta/stable stages requirements merged into the k/e repo. The KEp is currently still open

Milestone dates are Enhancement Freeze 7/30 and Code Freeze 8/29.

Thank you.

archetec commented 5 years ago

Why is this feature request keeps getting pushed to one Enhancement to another...? This is very important, not only for databases but also for Kafka clusters in production! Although it's possible to replicate to a new cluster with more storage, and then swtich over, it's not a viable solution. We need this!

kacole2 commented 5 years ago

@archetec have you joined the meetings for SIG Apps and SIG Storage to see how this can be prioritized? So far, this is in infant stages because the KEP hasn't been approved. That means there is no community consensus for implementation of this feature.

archetec commented 5 years ago

@kacole2 I understand, and I just started to read about this... Please forgive my partial understanding of the process.

Reading comments on #660 it looks like there's a solution in review. But yes I see it's not approved yet, and looks like it's getting pushed to 1.17.

gnufied commented 5 years ago

@archetec the KEP has been approved but @SidakM was fine with moving it to 1.17 since getting the KEP merged within 1.16 time frame required requesting KEP exception. It is tricky feature and it is important to get the details right. We should have this implemented in 1.17.

kcmartin commented 5 years ago

Hello @SidakM -- 1.17 Enhancement Shadow here! 🙂

I wanted to reach out to see if this enhancement will be graduating to alpha/beta/stable in 1.17?

 Please let me know so that this enhancement can be added to 1.17 tracking sheet.

Thank you!

SidakM-zz commented 5 years ago

@kcmartin The goal is to graduate to alpha in 1.17. Waiting for api review. @gnufied

/milestone v1.17

kcmartin commented 5 years ago

Hi @SidakM We're only 5 days away from the Enhancements Freeze (Tuesday, October 15, EOD PST). Another friendly reminder that to be able to graduate this in the 1.17 release, KEP must have graduation criteria defined, in an implementable state, and merged in.

SidakM-zz commented 5 years ago

@gnufied As mentioned above the freeze is on Tuesday. Haven't heard back for the api review since I responded to the comments in the kep. Can we reach out for an update?

gnufied commented 5 years ago

@SidakM I agree with @liggitt that for the spec to be implementable - https://github.com/kubernetes/enhancements/pull/660#discussion_r325233794 comment needs to be addressed. As I understand it, this scenario can happen even if resize was successful and hence could prevent an user from rolling back.

kcmartin commented 5 years ago

Hey @SidakM / @gnufied , unfortunately deadline for 1.17 enhancement freeze has passed and looks like the KEP is still open. I will be removing this enhancement from the 1.17 milestone.

Please note that you can file an enhancement exception if you need to get this in for 1.17

/milestone clear

As we are evolving to support resize in-use PVC, i think we need to support StatefulSet PVC change.
