## Summary by CodeRabbit

* **Configuration**
* Updated ingress-nginx controller to use NodePort exposure method
(ports 30000 for HTTP, 30001 for HTTPS) when configured as "Proxied."
  * Removed unnecessary hostNetwork configuration for the controller.
  * Service port mappings updated to align with new NodePort settings.
