The Kubernetes Service object exposes an application’s network interface, enabling clients to invoke the application via TCP or UDP. The most common usage of a Service is to expose an application’s HTTP endpoints. The type property of a Kubernetes Service dictates whether the application is exposed to the cluster internally or to clients external to the cluster. A Kubernetes Service with type: LoadBalancer is accessible from outside the cluster. In this example, Kubernetes exposes TCP port 80 to the outside world. Any TCP traffic received on port 80 is routed to port 9000 in the Pod’s container. All LoadBalancer Services receive an external IP. Clients outside of the cluster access the Service through this external IP.
