fixes issue: #19

Thanks for this! Just as an FYI, this is a half-baked idea I came up with before I realized dozzle does what I was aiming for, and does it much better. Honestly, I think this idea is still worth pursuing because I think it would be super nice to have a "management front end" for the SDR-E suite of containers that would enable starting, stopping, etc of containers.

Anyway, don't expect this thing to do much of interest, but it's cool to see people playing with it.
