Step 1
Go here and do what's written on it.
Step 2
You have two choices: the offical package from the Docker site or homebrew. I prefer homebrew because I like to manage my environment from the command line. The choice is yours.
brew update
brew install docker
brew install boot2docker
Step 3
First, we need to initialize boot2docker (we only have to do this once):
boot2docker init
2014/08/21 13:49:33 Downloading boot2docker ISO image...
[ ... ]
2014/08/21 13:49:50 Done. Type `boot2docker up` to start the VM.
we can start up the VM. Do like it says:
boot2docker up
2014/08/21 13:51:29 Waiting for VM to be started...
.......
2014/08/21 13:51:50 Started.
2014/08/21 13:51:51 Trying to get IP one more time
2014/08/21 13:51:51 To connect the Docker client to the Docker daemon, please set:
2014/08/21 13:51:51 export DOCKER_HOST=tcp://192.168.59.103:2375
Step 4
The Docker client assumes the Docker host is the current machine. We need to tell it to use our boot2docker VM by setting the DOCKER_HOST environment variable:
export DOCKER_HOST=tcp://192.168.59.103:2375
