Is it intended for this to work with flexvolume plugins? We still lack a solution for that use-case.

It is intended to work with all volume types. Including Flexvolume and CSI.

@gnufied please fill out the appropriate line item of the
1.11 feature tracking spreadsheet
and open a placeholder docs PR against the
release-1.11 branch
by 5/25/2018 (tomorrow as I write this) if new docs or docs changes are
needed and a relevant PR has not yet been opened.

@gnufied -- What's the current status of this feature?
As we haven't heard from you with regards to some items, this feature has been moved to the Milestone risks sheet within the 1.11 Features tracking spreadsheet.

Please update the line item for this feature on the Milestone risks sheet ASAP AND ping myself and @idvoretskyi, so we can assess the feature status or we will need to officially remove it from the milestone.

The PR is still on track for 1.11. The implementation PR is here - kubernetes/kubernetes#64154

We have approval from @saad-ali . We are waiting on approvals from @liggitt and @bsalamat . I just had to rebase the PR because the upstream changed and jordan requested some naming changes.

@gnufied -- there needs to be a Docs PR issued as well, as Misty mentioned above.
Please update the Features tracking sheet with that information, so that we can remove this feature from the Milestone risks tab.

Fix volume limit for EBS on m5 and c5 instances

This is a fix for lower volume limits on m5 and c5 instance types while we wait for kubernetes/enhancements#554 to land GA.

This problem became urgent because many of our users are trying to migrate to those instance types in light of spectre/meltdown vulnerability but  lower volume limit on those instance types often causes cluster instability. Yes they can workaround by configuring the scheduler with lower limit but often this becomes somewhat difficult to do when cluster is mixed. 

The newer default limits were picked from https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/volume_limits.html

Text about spectre/meltdown is available on - https://community.bitnami.com/t/spectre-variant-2/54961/5

@gnufied This feature was worked on in the previous milestone, so we'd like to check in and see if there are any plans for this to graduate stages in Kubernetes 1.12 as mentioned in your original post. This still has the alpha tag as well so we need to update it accordingly.

If there are any updates, please explicitly ping @justaugustus, @kacole2, @robertsandoval, @rajendar38 to note that it is ready to be included in the Features Tracking Spreadsheet for Kubernetes 1.12.

Please note that the Features Freeze is July 31st, after which any incomplete Feature issues will require an Exception request to be accepted into the milestone.

In addition, please be aware of the following relevant deadlines:

  • Docs deadline (open placeholder PRs): 8/21
  • Test case freeze: 8/28

Please make sure all PRs for features have relevant release notes included as well.

Happy shipping!

@kacole2 For 1.12 the plan is to further expand this feature to cover more volume types. Add CSI support. The decision to whether to move to beta in 1.12 or not will be taken in a day or two.

Hello @gnufied I'm one of the v1.17 docs shadows.
Does this enhancement for (or the work planned for v1.17) require any new docs (or modifications to existing docs)? If not, can you please update the 1.17 Enhancement Tracker Sheet (or let me know and I'll do so)

If so, just a friendly reminder we're looking for a PR against k/website (branch dev-1.17) due by Friday, November 8th, it can just be a placeholder PR at this time. Let me know if you have any questions!

Hey @gnufied @bertinatto , Happy New Year! 1.18 Enhancements lead here 👋 Thanks for getting this across the line in 1.17!!

I'm going though and doing some cleanup for the milestone and checking on things that graduated in the last release. Since this graduated to GA in 1.17, I'd like to close this issue out but the KEP is still marked as implementable. Could you submit a PR to update the KEP to implemented and then we can close this issue out?

Thanks so much!
