autoscaling/v2beta1 is no longer available in current kubernetes 1.25

W0909 13:41:26.043561    3885 warnings.go:70] autoscaling/v2beta1 HorizontalPodAutoscaler is deprecated in v1.22+, unavailable in v1.25+; use autoscaling/v2 HorizontalPodAutoscaler

expectation is to use proper api reference as autoscaling would not working in the last release of kubernetes

[anubisg1]

Error: UPGRADE FAILED: resource mapping not found for name: "netbox-netbox-worker" namespace: "" from "": no matches for kind "HorizontalPodAutoscaler" in version "autoscaling/v2beta1"
ensure CRDs are installed first

indeed it fails on kubernetes 1.25

This should be simple enough to fix with a similar set of conditions as the CronJob resource.

According to the deprecated API migration guide, v1.23+ supports the autoscaling/v2 API version, so something along the lines of

{{- if semverCompare ">=1.23-0" .Capabilities.KubeVersion.GitVersion -}}
apiVersion: batch/v2
{{- else -}}
apiVersion: autoscaling/v2beta1
{{- end }}

should do the trick.

v2 will be removed in 1.26. We should use stable versions: https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/#api-object

and since 1.26 is out now, we should be looking into fixing this.

This looks like it'll be resolved in the upcoming 5.0.0-release: 664c10b.
