I’m fan of maps (in real life and in games), and the map play here is interesting

Don't you hate to repeat yourself? For example, I hate working on anything related to user authentication or authorization that isn't directly related to the system I'm working on. I see it as necessary evil, an accidental complexity.

To be honest, I'm not sure what networking activity docker-compose is doing directly vs. what the docker daemon is doing.

It looks like your links for "this" and "that" no longer work, and I'd be really curious to see.
