as I posted on reddit: A simpler and better solution for this problem is: do not let apps run in background (double-fork/detach) in containers. Most applications that background by default can override this with a command-line flag. And certainly don't run programs that execute other programs that background. Keep it simple, and try to limit yourself to 1 process per container. Sure there might be situations where this cannot be avoided, but in 99% of the situations - this is not a problem. Yes you have to be aware of this potential problem, but I am currently running tons of containers, of which only a few run supervisord (which handles reaping too) to run multiple processes within one container because it was the sane thing to do. Stale zombie processes on my docker hosts? None. These precautions in my opinion are only required for badly behaving software. And yes - there is software like that.
