Tell us about your request Kubernetes 1.16 added a feature flag HPAScaleToZero to allow HPA scaling to/from zero. https://kubernetes.io/docs/reference/command-line-tools-reference/feature-gates/

Which service(s) is this request for? EKS

Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard? We have pods for RabbitMQ consumers that are idling for a long time when the queue is empty. We want them to spawn only when the queue has some messages.

Are you currently working around this issue? No.

Question: is enabling this feature dependent on kubernetes/enhancements/pull/2022 leaving "alpha"?

There's a broader issue which would cover this as well: https://github.com/aws/containers-roadmap/issues/512

could https://github.com/aws/containers-roadmap/issues/512#issuecomment-663924038 be a workaround?

Almost 1 year anniversary of this request. What can we do to move it forward?

Hello,

I ended up implementing a little tool https://github.com/machine424/kube-hpa-scale-to-zero that simulates this for Kube clusters that cannot enable the feature gate, awaiting for the feature gate to go GA.

Coming up on 2 years since I last asked about this. Any chance it will be implemented or at least acknowledged?

We switched to KEDA operator and scaledObjects, it is way more flexible.

Ya, would probably recommend just using Keda, much more flexible, fully in your control and not too difficult to use.
