Webhook registration configuration in Kubernetes

[suyanhj]

Problem

I found that almost all webhooks in the source code are configured by default to be registered to Kubernetes via URL. However, after the service is deployed to the cluster, I believe it should be accessed via the service method instead. I have checked all the official documentation and GitHub examples, but I couldn’t find any related configuration option. So, I would like to ask if there are any plans to add an optional configuration to choose between URL or service for the registration method in the future?

Proposal

Add optional registration configuration for the webhook

Code

def example():
    settings.admission.server = kopf.WebhookServer(addr='0.0.0.0', port=8443, host=conf.listen_host,service=service)

    class WebhookServer(webhacks.WebhookContextManager):
        def __init__(self, *args, **kwargs):
            ...
            self.service = service

        def __call__(self, *args, **kwargs):
            ...
            if self.service:
                client_config = reviews.WebhookClientConfig(service=self.service)
            ...
            client_config = reviews.WebhookClientConfig(url=url)
