title: kubernetes: loadbalancer service with a nodeport
body: <p>I have a LoadBalancer service which exposes 3300 port outside the cluster. I want to open a new port for internal communication so that other pods can talk to this service, but this port should not be exposed outside the cluster.<br />
  Basically, the communication looks like this:</p>
  <pre><code>                                   my-svc:3301
      pod/my-app  &lt;--- svc/my-svc  &lt;------------- pod/my-new-app
                        ^
                        | ext-ip:3300
                        |
                     outside_world
  </code></pre>
  <pre><code>apiVersion: v1
  kind: Service
  metadata:
    name: my-svc
  spec:
    type: LoadBalancer
    ports:
    - name: my-port
      protocol: &quot;TCP&quot;
      port: 3300
      targetPort: 3300
    selector:
      app: my-app
  </code></pre>
  <p>Is there a way to include the new port inside this service itself? Do I have to create another service of type NodePort?</p>
