Hi, this is a great article. Covers many important stuff.

I have a few questions though:

1. Could you recommend on some easy resources for creating the front end itself? I would like to configure it’s appearance, allow opening the camera on mobile devices, etc.
2. I didn’t get what was the purpose of step 2… If everything is defined in the docker-file, and we push the app to the various deployment services straight from git-hub/PC, why should we spend the time to initiate and push the docker image to dockerHub?
