How to define external ip for kubernetes ingress

Question

I have question about kubernetes ingress.

I want to use ingress with my Amazon account and/or private cloud and want to assign external IP.

It is possible to assign external ip for services : Services documentation - chapter external IP but cannot find a way to do that for Ingress : Ingress documentation.

My question is direct especially to Kubernetes team. Similar question was asked by Simon in this topic : How to force SSL for Kubernetes Ingress on GKE 2 but he asked about GKE while I am interested in private cloud, AWS.

Thank you in advance.

[UPDATE]

Guys found that my question may was answered already in this topic. Actually answer that @anigosa put there is specific for GCloud. His solution won't work in private cloud neither in AWS cloud. In my opinion the reason for that is that he use type: LoadBalancer (which cannot be used in private cloud) and use loadBalancerIP property which will works only on GCloud(for AWS it cause error : "Failed to create load balancer for service default/nginx-ingress-svc: LoadBalancerIP cannot be specified for AWS ELB ").

Looking at this issue, it seems you can define annotation on your service and map it to existing elastic ip. Something like that:

apiVersion: v1
kind: Service
metadata:
  name: my-service
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-eip-allocations: <>
spec:
  type: LoadBalancer
  selector:
    app: MyApp
  ports:
    - protocol: TCP
      port: 80
      targetPort: 9376

Please note this will create ELB for this service, not ingress.

As an ingress is simply one service (=ELB) handling requests for many other services, it should be possible to do something similar for ingress, but I couldn't find any docs for it.
