Enhancement Description

  • One-line enhancement description (can be used as a release note): Allow changes to storage requests in StatefulSets.volumeClaimTemplates to propagate to associated PVCs.
  • Primary contact (assignee): @SidakM
  • Responsible SIGs: sig-apps
  • Design proposal link (community repo): Add StatefulSet Volume Expansion Kep #660, KEP-0661: StatefulSet volume resize #2842
  • Link to e2e and/or unit tests:
  • Reviewer(s) - (for LGTM) recommend having 2+ reviewers (at least one from code-area OWNERS file) agreed to review. Reviewers from multiple companies preferred: @janetkuo @gnufied
  • Approver (likely from SIG/area to which enhancement belongs):
  • Enhancement target (which target equals to which milestone):
    • Alpha release target (x.y)
    • Beta release target (x.y)
    • Stable release target (x.y)

Please to keep this description up to date. This will help the Enhancement Team track efficiently the evolution of the enhancement

@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 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 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

@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.

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

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.

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.

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!

@xing-yang This is now being actively discussed with the help of @gnufied and @jsafrane . @areller and I are working together on the KEP. Thanks

Make the cache size field immutable

Currently we are using StatefulSet volumeClaimTemplate to provision the PVC. However the corresponding StatefulSet field that controls the PVC size is immutable. It is not possible to resize/enlarge the underlying PVC through the StatefulSet spec. See kubernetes/enhancements#661
This commit makes the cache size field immutable until we decide how to implement the resize.

Yeah - this would really be nice to support - it makes production harder than it needs to be - having to delete and recreate statefulsets - ensuring pods aren't killed with cascade=false

We have created #4650 , and working on it at #4651 . The new KEP allows arbitrary changes to the volumeClaimTemplates, it should cover the use-case of this KEP, and more.

@huww98 does this means you're replacing #661 and we should close the other?
