Can Packer meaningfully work with Docker.io? I gather there is some overlap, but is there a way they can work together? It seems to me: * Packer abstracts creation of images. * Vagrant abstracts running images, via a VM, and applying changes to images (via chef/puppet, although that seems to overlap with Packer as well). * Docker seems to abstract both creation of images (via docker build) and running of images (albeit only on top of LXC). To complicate things further, it seems like Vagrant has some initial support for running (Linux) images on top of LXC (via Fabio Rehm's plugin) and possibly on top of Docker (although the state of the plugin for this is vague). All this stuff seems very powerful, but the overlap is confusing. My head hurts...
