## Configuring webhook endpoint certificate

By default, the webhook certificate is managed by the dynamic certificate service. To use your own certificate, you can use the `tlsConfig` property. Below is an example of how to set it up:

```yaml
apiVersion: webhook.config.cert-manager.io/v1alpha1
kind: WebhookConfiguration
tlsConfig:
filesystem:
certFile: /etc/certs/tls.crt
keyFile: /etc/certs/tls.key
```

> **Notes:**
> - Using this configuration will disable the default `--dynamic-serving-` flags.
> - Remember to mount your certificate files into the webhook deployment using volumes and volumeMounts.
