title: How to run node.js on port 80 inside Docker
body: <p>Let's say I have <a href="https://github.com/RocketChat/Deploy.to.Cloud/blob/pierreozoux-fix-proposal/OfficialImage/Dockerfile" rel="noreferrer">this Dockerfile</a>.</p>
  
  <p>What would be the best way to run it as non privileged user on port 80? (without adding a webserver in front)?</p>
  
  <p>I tried to set up this: <a href="https://stackoverflow.com/questions/6109089/how-do-i-run-node-js-on-port-80/27805105#27805105">How do I run Node.js on port 80?</a>
  But I wasn't lucky, I think I don't understand deeply how this work.</p>
  
  <p>Do you think there is an elegant solution to solve this issue? I'm doubtful, but hopeful :) </p>
