install Docker Toolbox

brew cask install dockertoolbox
create a host machine, since we're on OSX and cannot run docker natively
docker-machine create --driver virtualbox default
The command also creates a machine configuration in the ~/.docker/machine/machines/default directory. You only need to run the create command once. Then, you can use docker-machine to start, stop, query, and otherwise manage the VM from the command line.
connect your shell to the newly created machine
eval "$(docker-machine env default)"
run hello-world to verify the setup
docker run hello-world
Hello from Docker. This message shows that your installation appears to be working correctly.
