I appreciate what docker did in pushing a more accessible UX on top of containerization and getting people to think more about reproducible setups and sandboxing. Its popularity was definitely one of the catalysts in that direction.

I'm curious if when you were originally designing it, what tradeoffs you chose between, for example did you consider a non-daemonized design or was it daemonized from the beginning?

Having had some time now and also seeing how other people have riffed off of the idea and refined it, what would you have done differently? If you have a retrospective at some point already, I'd be interested to read it.

I have some accumulation of personal architectural guidelines that I built up from trial-and-error + reading others' experience and reflecting on how their design could've affected something I made. As a result, I really value those kinds of discussions about tradeoffs.
