title: How to make use of Kubernetes port names?
body: <p>In a kubernetes <strong>deployment</strong> I specify a port like so:</p>
  
  <pre><code> containers:
   - name: nginx
     image: nginx:latest
     ports:
      - name: nginx-port
        containerPort: 80
        protocol: TCP
  </code></pre>
  
  <p>Now in a <strong>service</strong> I can reference that port like so (allows me to only specify the external port in the service):</p>
  
  <pre><code>spec:
    type: ClusterIP
    ports:
    - name: nginx-port
      port: 80
      targetPort: nginx-port
      protocol: TCP
  </code></pre>
  
  <p>Now the question, can I reference service and port elsewhere using the following syntax <code>nginx-service.default.svc.cluster.local:nginx-port</code>? You know I can make reference to services using this special names, but I find myself hardcoding the port number like so <code>nginx-service.default.svc.cluster.local:80</code>.</p>
