How do I get client IP addressed from HTTP requests in kubernetes services

Question

I'm running my web app as pod behind an nginx reverse proxy for ssl. Both of them use kubernetes service for load balancing(Like shown here). My problem is that all of the HTTP request logs show the cluster IP address instead of the IPs of the HTTP clients. Is there any other way I can make kubernetes service to pass this info to my app servers?

Kube-proxy can get out of the loop in one of two ways:

1. Use ingress to configure your nginx to load balance based on the source IP address and then you cna send traffic to your endpoint(https://github.com/kubernetes/contrib/tree/master/ingress/controllers#ingress-controllers)
2. OR you can use the haproxy loadbalancer and set the balance annotation of your service so that it uses "source"(https://github.com/kubernetes/contrib/blob/master/service-loadbalancer/service_loadbalancer.go#L51)
