Install docker-machine in your Boot2Docker VM

Boot2Docker still has a non-persistent filesystem.
The following commands will download docker-machine and install it in /usr/local/bin at each image start.

Once again, we will modify the /var/lib/boot2docker/bootlocal.sh file :

sudo vi /var/lib/boot2docker/bootlocal.sh

We add the following commands to automatically install docker-machine 0.5.2 :

# install docker machine
curl -L https://github.com/docker/machine/releases/download/v0.5.2/docker-machine_linux-amd64.zip > machine.zip && \
   unzip machine.zip && \
   rm -f machine.zip && \
   sudo mv -f docker-machine* /usr/local/bin
