title: Liveness probe with http post
body: <p>I'm running a web service that I can not change any of the specifications. I want to use liveness probe with HTTP POST on Kubernetes. I couldn't find anything available. All of my efforts with busybox and netcat have failed. </p>
  
  <p>Is there a solution? Is it possible to build a custom liveness probe from any Linux dist?</p>
