Discussion on: Why Docker? Creating a multi-container application with docker

r0bnet profile image

Nice introduction. I missed two things that may not be clear for beginners.

  1. The image shows 5 containers (or container like objects) but there are only 4. The app is included via volumes. That confused me when i saw the pic but i got it when i read the article.
  2. I think you forgot to explain the "links" statement as part of the web container. With that it's possible to directly address the app container in the nginx config.

Keep going! :)
