docker-machine-do

Run a command on each machine available with docker-machine ls.

Docker makes it quick and easy to manage updates inside of a container, but when you're managing lots of virtual machines it's hard to ensure that you're running all of the commands on all of the machines. You could create a Unix pipe monstrosity between docker-machine and xargs and sh or maybe even something clever like xpanes, but using this project is simpler, easier, and maybe even more colorful.
