Can someone explain how docker relates to SupervisorD? It seems like it can be used for somewhat the same thing, but has more power around committing config cha

  There is superficial overlap between Docker and traditional process supervisors - both will fork/exec your application, monitor its status, collect logs etc. And indeed in a simple test/development setting, you can use Docker without the overhead of installing supervisord, runit, upstart etc. But once you're in production, you typically want to combine the two: a process supervisor to manage the boot process of your machine, auto-restart etc. (typically upstart on Ubuntu, systemd on Red Hat 7+, etc.). In this case, the supervisor simply calls out to docker, which "wraps" your application in a way similar to chroot. I hope this helps.
