If your REALLY want to run docker on FreeBSD, get a Mac. The kernel is derived from FreeBSD 4.x and there are "native" docker implementations available for that OS ... well, sort of. In order to make it work, they have to run a linux kernel behind the scenes. But this illustrates why cross-OS docker implementations are terrible. Thought it's getting better, that implementation is dreadfully slow, particularly with file I/O. I forget the detail now, but running docker natively in a VM running on OSX was something like 6x faster on file I/O than the "native" OSX docker implementation.
