How to Configure Ingress Controller Forwarding Rules

Hi, I’d like to configure my forwarding rules for a Load Balancer I have set up through the Ingress Controller in my Kubernetes Cluster.

As I understand it, editing this manually is a bad idea since these objects may be recreated for whatever reason.

What is the recommended way to edit a forwarding rule given this scenario?

Specifically, I’d like to specify the certificate to use for my HTTPS and point it to the HTTP node port

Thanks
