title: Ngnix: setting up multiple websites with SSL/Docker
body: <p><strong>I need to set up a server that does multiple things:</strong></p>
  
  <ul>
  <li>Hosts a Grafana instance on docker (<code>3000</code> is the default port)</li>
  <li>Hosts a flask service for printing Grafana reports (the default Grafana printing sucks so I built a Selenium robot to grab the objects on the screen, create a PDF and download the results)</li>
  <li>Hosts a Docker App built with Wappler (Php-based app builder)</li>
  </ul>
  
  <p>I'd like to use free certs (lets encrypt).</p>
  
  <p>I'm new to docker and new to linux server administration. What's the best resource for learning how to set this up? </p>
