title: How doe's Kubernetes port forward work? is it a secure and responsive method to view GUI?
body: <p>I have a Kubernetes cluster which doesn't need to expose ports to the public. I am installing monitoring and logging (Prometheus &amp; Loki or Elastic) for in house use and would like to use their GUI. I could provision https ingress and limit IP access but port forwarding seems to work.</p>
  <ol>
  <li>How Does port forwarding work, under the hood?</li>
  <li>Is port forwarding as secure as my kubectl connection?</li>
  <li>Is the connection as fast as an ingress load balancer based HTTPs connection?</li>
  </ol>
