Well first of all Apple has shown no interest in adding jails to osx. Second, there is not yet a proof of concept implementation of Docker using jails (there are significant differences between the implementation of jails and Linux namespacing). Third, you need a filesystem like zfs, but Apple does not support that. Fourth, all Docker code currently being distributed is for Linux/amd64. Implementing it on FreeBSD would be immensely easier as a first step.
