No, not really.  Docker is a higher level "solution" in line with
VirtManager (virtsh), LXD (from the LXC project) and Virtuoso
(commercial OpenVZ packaging) that supports multiple lower layers (much
like VirtManager).  Docker has and can use the LXC backend as their low
level container layer and can manage LXC containers.  I've played with
it a bit.  It's just another abstraction and doesn't supercede any of
the others.  Docker's been getting alot more press lately.

Regards,
Mike
