Docker is a mechanism for creating virtual "appliances" by putting some 
software and all its dependencies in a virtual machine image so that it 
can be easily deployed without having to worry about dependencies.

It seems interesting but I can't imagine why anyone would need it.  But 
I'm not a systemsy person so ... who knows.
