GKE now supports Internal Load Balancers: https://cloud.google.com/kubernetes-engine/docs/how-to/internal-load-balancing

It's primary use case is to have a load balancer that's not exposed to the public internet so a service running on GKE can be reached from other GCE VMs or other GKE clusters in the same network.
