I'm working through some of the tutorial material on the Docker site, and thought I'd throw this up here. As of this writing, my work with Docker has been extra-curricular, but it's being discussed seriously where I work, so I thought I'd get a little more systematic in my approach. I tried to follow the site's layout, directory-wise, but likely slipped here and there.
Mostly, it's just my own observations. Take it for what it's worth. YMMV.
