## Building and releasing Guestbook Image
Guestbook build process employs the usage of docker-in-docker to build an image within another. This requires that the build image has access to the `docker` program's binary, which defaults to the docker available on your host machine. In the case of boot2docker, `DOCKER_BIN` must be set to the binary's location in the boot2docker's vm.
This process employs building two docker images, one compiles the source and the other hosts the compiled binaries.
Releasing the image requires that you have access to the docker registry user account which will host the image.
