title: Kubernetes how to access a service from another namespace
body: <p>I'm using
  <a href="https://github.com/Yolean/kubernetes-kafka" rel="noreferrer">https://github.com/Yolean/kubernetes-kafka</a>
  to run kubernetes on minikube
  I exposed an outside port and successfully used producers and consumers from outside the cluster</p>
  
  <pre><code>➜  ~ kubectl get svc --namespace kafka

  <p>How do I access the service from pods in 'default' namespace by name not using the out facing url?    </p>
