title: Not able to access statefulset pod via headless service using fqdn
body: <p>I have a k8 setup that looks like this</p>
  <p><code>ingress -&gt; headless service (k8 service with clusterIp: none) -&gt; statefulsets ( 2pods)</code></p>
  <p>Fqdn looks like this:</p>
  <pre><code>nslookup my-service
  Server:         100.4.0.10
  Address:        100.4.0.10#53
  
  Name:   my-service.my-namespace.svc.cluster.local
  Address: 100.2.2.8
  Name:   my-service.my-namespace.svc.cluster.local
  Address: 100.1.4.2
  </code></pre>
  <p>I am trying to reach one of the pod directly via the service using the following fqdn but not able to do so.</p>
  <pre><code>curl -I my-pod-0.my-service.my-namespace.svc.cluster.local:8222
  curl: (6) Could not resolve host: my-pod-0.my-service.my-namespace.svc.cluster.local
  </code></pre>
  <p>If I try to hit the service directly then it works correctly (as a loadbalancer)</p>
  <pre><code>curl -I my-service.my-namespace.svc.cluster.local:8222
  HTTP/1.1 200 OK

  </code></pre>
  <p>If I try to hit the pod directly using it's cluster ip,  it also works fine</p>
  <pre><code>curl -I 100.2.2.8:8222
  HTTP/1.1 200 OK
  Date: Sat, 31 Jul 2021 21:29:22 GMT

  <p>But my use case requires me to be able to hit the statefulset pod using fqdn i.e <code>my-pod-0.my-service.my-namespace.svc.cluster.local</code> . What am I missing here?</p>
