It is, in essence, LXC containers combined with an overlay filesystem.
It's basic PaaS with a Go binary ("docker") wrapped around LXC. It's
neat in the same sense as Vagrant -- you can ship a Dockerfile which
can reproduce your environment very easily, and the Docker team itself
has wrapped all the images in a git repository you can easily branch
from/etc. That said, Docker support won't land in Fedora until F20,
and CentOS around the same time (officially).
I'll admit that I don't get the hype around Docker, since it doesn't
do anything that LXC doesn't already do, but the templating and a
user-friendly binary is nice.
I wonder if there's interest in shipping oVirt docker containers.
I'm interested in Docker to ease the process of building Node images,
at least. oVirt Docker containers would be interesting, assuming LXC
support isn't painful, since the CoreOS (where Docker originated) also
relies on an image with readonly root and overlays on top, so there's
some overlap.
One "nasty" secret of CoreOS is that they are using aufs - a fuse
overlay fs - and that's just not nice.
All this stuff requires a decent union-mount support.
Just my 2ct.
Otherwise it's also totally interesting!
