A simple project that encapsulates Packer templates for building Vagrant baseboxes.
You need:
Inside the packer
directory, a JSON file describes each box that can be built. You can use packer build
to build the boxes. So, you can customize the JSON files
$ git clone git@github.com:rgaidot/machine-builders.git
$ cd machine-builders ; cd packer
$ packer build -only=virtualbox-iso debian-wheezy-amd64.json
Machine builders use shell scripts to get software installed and configured on a machine. Check out JSON files.
