NodePort

Service which listens to a port in the Kubernetes cluster and forwards external traffic to an internal pod. External ports are between 30000-32767 range.

The traffic is redirected randomly to the selected pods.

The following snippet creates a NodePort service to map the 30008 port to the 80 of any pod labeled with app: myapp.
