Were you using Linux developer machines? Docker, Inc. provide ready-made installers for Windows and Mac - the Docker ToolBox makes setting up on those OSes very easy these days. I haven't tried the new products that replace ToolBox yet.
I can imagine it being harder on some Linux distributions because your host system will have to have all of the kernel bits etc. Ubuntu 14.04 and above or current versions of Fedora should be good - the distributions explicitly support Docker, and Docker, Inc. provide packages so that you can run either the distribution packages or the Docker, Inc. ones.
