NGINX Ingress running in AWS

This example shows how is possible to use the nginx ingress controller in AWS behind an ELB configured with Proxy Protocol.

kubectl create -f ./nginx-ingress-controller.yaml

This command creates:

• a default backend deployment and service.
• a service with type: LoadBalancer configuring Proxy Protocol in the ELB (service.beta.kubernetes.io/aws-load-balancer-proxy-protocol: '*').
• a configmap for the ingress controller enabling proxy protocol in NGINX (use-proxy-protocol: "true")
• a deployment for the ingress controller

Is the proxy protocol necessary?

No but only enabling the procotol is possible to keep the real source IP address requesting the connection.
