apiextensions.k8s.io/v1beta1 apiVersion removed on k8s v1.19.0

[lspecian-olx]

Description

The apiextensions.k8s.io/v1beta1 apiVersion used in the CustomResourceDefinition was removed on k8s v1.19.0

Importance

The issue is a blocker to install the chart properly on k8s clusters with version v1.19.0

Location

Suggestions for an improvement

I suggest the issue should be fixed by checking the apiVersion with .Capabilities.APIVersions.Has

{{- if .Capabilities.APIVersions.Has "apiextensions.k8s.io/v1" }}
apiVersion: apiextensions.k8s.io/v1
{{- else }}
apiVersion: apiextensions.k8s.io/v1beta1
{{- end }}
