> gunzip ld.tgz 
> tar xvf ld.tar 
> sudo cp usr/local/bin/docker /usr/local/bin

Specify the docker deamon Host for the client:

Initialize boot2docker VM and run deamon

Initialize the VM:

> boot2docker init

2014/06/06 09:55:47 Started.
2014/06/06 09:55:47 To connect the Docker client to the Docker daemon, please set:
2014/06/06 09:55:47     export DOCKER_HOST=tcp://localhost:4243

Test:

> docker version
Client version: 0.11.1
Client API version: 1.11
Go version (client): go1.2.1
Git commit (client): fb99f99
Server version: 0.11.1
Server API version: 1.11
Git commit (server): fb99f99
Go version (server): go1.2.1

Setup forward network ports. According to the documentation, the boot2docker VM must be powered off for this to work:

> boot2docker stop

Run following script (this takes a while):

for i in {49000..49900}; do
 VBoxManage modifyvm "boot2docker-vm" --natpf1 "tcp-port$i,tcp,,$i,,$i";
 VBoxManage modifyvm "boot2docker-vm" --natpf1 "udp-port$i,udp,,$i,,$i";
done

Starting docker VM again and login using ssh:

> boot2docker up
> boot2docker ssh

Then you should see:

                        ##        .
                  ## ## ##       ==
