Seconded. My biggest stumbling block with Docker at the moment is “best practices”, as I work on coming up with a Docker Dev Ecosystem (for myself and for a team).
Same here. I've cooked something built around bash scripts and guest-to-host sharing of source code, and I can't help but have a nagging feeling that it isn't as good or correct as it should be...or perhaps it's just totally wrong altogether.
In the absence of "best practices" even a discussion thread somewhere that allows Docker users to pick apart and discussion configurations would be helpful. Pretty much all I've been able to find is a smattering of blog posts.
