Multiplatform support

[gh2k]

I'd like to see multiplatform support on here, with the advent of Windows containers. We have a mixed-mode environment and it's been hard to find a framework that works.

AFAIK Docker Swarm Mode is the only thing that officially supports Windows containers. All other implementations appear to be in some form of experimental state or nonexistent, but I'd like to be able to keep track of that.
