Rate limiting of v1beta1.external.metrics.k8s.io

[bpinske]

I have keda deployed in all of my environments and I notice that I am getting spammed in all of them with rate limiting notices. Including environments which are not actually using Keda at all yet. Is there anything that I should be doing to address this, or is this a known issue of some sort? I don't see any documentation around this situation. I haven't seen any ill effect on keda's performance where I am actually using it.

Keda version: 2.0.0

Thanks @bpinske . I am seeing those errors as well (in AWS EKS 1.18)

Looks like we should do something like this?: kubernetes-sigs/prometheus-adapter#335

Yeah, update of the https://github.com/kubernetes-sigs/custom-metrics-apiserver deps and related code should help. Though it may not be that easy step, as there might be dependency conflicts between mainly (k8s) deps used by KEDA and the updated version of custom-metrics-adapter :(

@zroubalik I will make those changes and send a PR "soon" (have done similar changes for other customer metrics servers, so familiar with the details)

@surki that's great, thanks for doing that!
