title: K8s service not pingable
body: <p>I have a k8s service/deployment in a minikube cluster (name <code>amq</code> in <code>default</code> namespace:</p>
  
  <pre><code>D20181472:argo-k8s gms$ kubectl get svc --all-namespaces

  <p>I spun up infoblox/dnstools, and tried <code>nslookup</code>, <code>dig</code> and <code>ping</code> of <code>amq.default</code> with the following results:</p>
  
  <pre><code>dnstools# nslookup amq.default

  dnstools# ping amq.default

  <p>(NB: pinging the ip address directly gives the same result)</p>
  
  <p>I admittedly am not very knowledgable about the deep workings of DNS, so I am not sure why I can do a lookup and dig for the hostname, but not ping it. </p>
