Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions. Using the concepts of "labels" and "pods", it groups the containers which make up an application into logical units for easy management and discovery.

When I use type: LoadBalancer on a GKE service, the controller provisions a TCP load balancer. Is it possible to have an SSL proxy (targetSslProxy) with it? Note that the application layer protocol is not HTTP, so I do not want an ingress.
