Update to k8s.io/api/admissionregistration/v1

[invidian]

k8s.io/api/admissionregistration/v1beta1 is deprecated since Kubernetes 1.16+ and will be removed in 1.22+. Code should be updated to use new API types.

This bug causes kube-webhook-certgen to bail/fail on Kubernetes 1.22:

jorik@argon:$ kubectl logs -n monitoring kps-admission-patch--1-mtzsk
W0826 10:16:43.550360       1 client_config.go:608] Neither --kubeconfig nor --master was specified.  Using the inClusterConfig.  This might not work.

For anyone finding this issue, as per @vsliouniaev

I no longer have access rights to this repository and it is no longer being maintained by the company. There is already a fork of this in the ingress-nginx repo, which has updated APIs and is hosted on GCR: https://github.com/kubernetes/ingress-nginx/blob/main/charts/ingress-nginx/values.yaml#L569

[ousiax]

please try to use k8s.gcr.io/ingress-nginx/kube-webhook-certgen:v1.1.1 instead.

I'll close this issue as k8s.gcr.io/ingress-nginx/kube-webhook-certgen is now likely considered upstream.

I'll lose this issue as k8s.gcr.io/ingress-nginx/kube-webhook-certgen is now likely considered upstream.

I think this issue should be left open for exactly this reason.
