title: Can't access service in my local kubernetes cluster using NodePort
body: <p>I have a manifest as the following</p>

    type: NodePort
    selector:
      name: my-redis
    ports:
    - name: redisport1

      nodePort: 30036
      protocol: TCP
  </code></pre>
  
  <p>This is a sample that reproduces my problem. My intention here is to create a simple cluster that has a pod with a redis container in it, and it should be exposed to my localhost. Still, get services gives me the following output:</p>
  
  <pre><code>redis-service   NodePort    10.107.233.66   &lt;none&gt;        6379:30036/TCP   10s
  </code></pre>
  
  <p>If I swap NodePort with LoadBalancer, I get an external-ip but still port doesn't work. </p>
  
  <p>Can you help me identify why I'm failing to map the 6379 port to my localhost, please?</p>
  
  <p>Thanks,</p>
