This steps assume we already have a Cluster created with VPC-native traffic routing enabled.
Before the need of the HTTP(S) LoadBalancer, I would just apply the manifests provided by the NGINX DOCS page for the installation of the Nginx Ingress Controller and It would create a service of type LoadBalancer which would, then, create a regional L4 LoadBalancer automatically.
But now that I need need to have Cloud Armor and WAF, the L4 Loadbalancer doesn't support it. A HTTP(S) Load Balancer is needed in order to Cloud Armor to work.
In order to have Nginx Ingress controller working with the new HTTPS(S) LoadBalancer we need to change the type: LoadBalancer on the Nginx Ingress Controller service to ClusterIP instead, and add the NEG annotation to it cloud.google.com/neg: '{"exposed_ports": {"80":{"name": "ingress-nginx-80-neg"}}}'. We do that because we don't want it to generate a L4 LoadBalancer for us. Instead, we will manually create an HTTP(S) LoadBalancer and bind it t
