Re:What I found wrong in Docker 1.12

I've been using Docker in production for the past 2 and a half years (in two different companies) and even with no extreme use cases we've had problems with: performance of volumes/devicemapper, random breaking bugs: daemon would restart without warning or errors in 1.4, randomly killing containers in 1.9, having to restart the daemon in 1.8 when it hung pulling images (consequently killing the containers in the process).
I still like Docker and can see myself, team and company using it for a long time if nothing MUCH better show up (rkt is promising to take some of the complexity pain away but we are not diving into it yet) but I can't say I've not been bitten enough to completely avoid upgrading Docker if it isn't needed, we follow a rule to only upgrade to ".1" releases as most of our problems have been with ".0" ones.

My favorite was docker exec -it $container bash would cause a nil pointer deterrence in docker 1.6.0 and kill the docker daemon. We've seen gobs of bugs since, but that was the most wtf gnarly one
