I don't understand how this could be flagged as a dupe. I agree both articles cover Portainer. But one goes deep into how to set it up with deep integration on Docker Machine and DigitalOcean on a more expert level. While the other provides a very simple beginner level Play with Docker setup and then goes on how to install an entire application stack, with frontends, databases and workers.
