Hi @johanneswuerbach

1.20 Enhancements Lead here checking in. Do you intend to go beta in 1.20? If so, please note that the Enhancements Freeze is October 6th, by which time your KEP should be:

  • implementable
  • have test plans
  • have graduation criteria.

I left a comment on your KEP with some notes to bring it to the correct dir structure. Let me know if you have any questions.

Best, Kirsten

Issues go stale after 90d of inactivity. Mark the issue as fresh with /remove-lifecycle stale. Stale issues rot after an additional 30d of inactivity and eventually close.

If this issue is safe to close now please do so with /close.

Send feedback to sig-testing, kubernetes/test-infra and/or fejta. /lifecycle stale

Looks like lots of users want this. +1 for seeing this get into beta

This seems like a very common use-case for building serverless-like services

Hey, we're aware that a lot of people want to see this feature make it to beta and that's great to see!

As can be seen in the associated PR ( #2022 ) there's some interactions with existing functionality that solutions have had to be found for, but progress is being made on this. If anyone wants to help drive this work forward, your feedback on the KEP PR is welcome, or feel free to reach out to us in the #sig-autoscaling channel in the Kubernetes slack.

(As a side note, if you're simply wanting to see this feature graduate to beta/GA, can you just give the initial comment a 👍 rather than adding further comments.)

Hello,

Awaiting for HPA HPAScaleToZero to get promoted, I implemented a little tool https://github.com/machine424/kube-hpa-scale-to-zero that simulates this for Kube clusters that cannot enable the feature gate. (Managed clusters especially). No more nodes that only work 3 hours a day :)
