up being useful for some internal test and dev work on my side.  Including
building/shipping apps to customers that I used to send out as qcows.  I
could certainly do this without nova-docker and go straight to docker, but
this is "more fun", and fits with my existing workflow/usage of OpenStack
for various things.

Also FWIW Magnum currently is way overkill for what I'm doing, just like
some other projects.​  I do plan to check that out before long, but for now
it's a bit overkill for me.
