title: How to expose internal services in Kuberenetes via ingress controller
body: <p>I have many services deployed in K8s, some of the services are exposed externally using Ingress controller and DNS is registered in AWS Route 53.
  There are some internal services which are to be used strictly internally.
  what are the ways to access internal services in K8s?
  FYI..I have core dns enable and service to service communication should happen via ingress controller nginx.conf file.</p>
  <p>Regards</p>
