I found the register cert with kubernetes api is misleading. Nothing to do with k8s version. https://github.com/denverdino/lxcfs-admission-webhook/blob/master/deployment/webhook-create-signed-cert.sh#L87

Just to create a tls with openssl is enough.Like below https://pet2cattle.com/2021/08/kubernetes-mutating-webhook
