UI-Ingress is Deprecated

[markusheinemann]

• Which image of the operator are you using? v1.6.3 helm chart from github repository
• Where do you run it - cloud or metal? Kubernetes or OpenShift? OVH managed Kubernetes
• Are you running Postgres Operator in production? no
• Type of issue? Bug report

I setup the postgres-operator-ui using helm. In the values.yaml I have setup an nginx ingress with the following configuration:

ingress:
  enabled: true
  annotations:
    kubernetes.io/ingress.class: nginx
    kubernetes.io/tls-acme: "true"
  hosts:
    - host: ui.yourname.xyz
      paths: [""]
  tls:
    - secretName: postgres-operator-ui-tls
      hosts:
        - ui.yourname.xyz

During the installation I get this deprecation warnings:

W0802 18:44:38.032843   17478 warnings.go:70] networking.k8s.io/v1beta1 Ingress is deprecated in v1.19+, unavailable in v1.22+; use networking.k8s.io/v1 Ingress
W0802 18:44:38.938036   17478 warnings.go:70] networking.k8s.io/v1beta1 Ingress is deprecated in v1.19+, unavailable in v1.22+; use networking.k8s.io/v1 Ingress
W0802 18:44:39.062773   17478 warnings.go:70] networking.k8s.io/v1beta1 Ingress is deprecated in v1.19+, unavailable in v1.22+; use networking.k8s.io/v1 Ingress

I expect the chart installing without the deprecation warnings.

I think the fix is relative easy. Just updating the apiVersion in the ingress template and double-check if there are any incompatibilities with the new version. The old version will not longer supported with K8S release 1.22.
