Ehh... the actual "make a container out of this chunk of the filesystem" bit can be done in a couple hundred lines of Ruby/Python/Perl - Docker is, of course, just telling the kernel to create new uid/filesystem/network/etc namespaces and what to put in them. Most of Docker is the image management system and build tool.
