To install Docker on OSX, you're going to need to install a few prerequisites.
Now we can finally install Docker. We also need to install boot2docker.
brew install docker brew install boot2docker boot2docker init boot2docker up export DOCKER_HOST=tcp://localhost:2375
And test it:
Bear in mind that if boot2docker has a different port than 2375, use the correct one, and don't put a trailing slash either.
