title: Kubernetes - what does <unset> mean in port in a service?
body: <p>I have a service exposed of type=LoadBalancer and when I do a</p>
  <p><code>kubectl describe services servicename</code>,</p>
  <p>I get this output :</p>
  <pre><code>Name:           ser1
  Namespace:      default
  Labels:         app=online1
  Selector:       app=online1
  Type:           LoadBalancer
  IP:         10.0.0.32
  External IPs:       192.168.99.100
  Port:           &lt;unset&gt; 8080/TCP
  NodePort:       &lt;unset&gt; 30545/TCP
  Endpoints:      172.17.0.10:8080,172.17.0.11:8080,172.17.0.8:8080 + 1 more...

  </code></pre>
  <p>Can someone please guide on the following doubts :</p>
  <p>1.) I can't understand what <code>&lt;unset&gt;</code> means in Port and NodePort. Also, how does it affect my service?</p>
  <p>2.) When I want to hit a service, I should hit the service using <code>&lt;external-ip:NodePort&gt;</code> right? Then what's the use of Port?</p>
