autoscaling/v2beta2 is deprecated in k8s 1.23

[kvasilopoulos]

Yatai states that it works with Kubernetes clusters with version 1.20 or newer.

We have 1.26 and we get the following error:

After some digging, I found the following issue kubernetes/ingress-nginx#8599 which states that you should upgrade the autoscaling in v2 if you have k8s higher than 1.23.

$ kubectl get apiservices | grep autoscaling
v1.autoscaling                              Local                        True        81d
v1alpha1.autoscaling.k8s.elastic.co         Local                        True        4d
v2.autoscaling                              Local                        True        81d

Thanks for your report! I will fix it ASAP

[kvasilopoulos]

Hi, @yetone do you have an ETA on this? Thanks!

[yetone]

@kvasilopoulos I will finish this next week

[kvasilopoulos]

@yetone Thanks!!

@yetone
Hello!
We also have the same issue. Any update on this fix?

[alexisthedude]

Hi @yetone
We are pretty stuck waiting for this... Yatai is fantastic and we all loved it so much that we got it in every step of what we do. Yet we need to keep up-to-date with k8s too, so we are up in the air without either Yatai or k8s updates
Is there any ETA on this?
