Masterless Puppet using a Puppetfile

The problem

When running Puppet in masterless mode, meaning there is no Puppet Master for the node to connect to, one of the problems you have to solve is how to get all your Puppet modules onto the node. Without going into all the possible ways of doing this, one nice and clean way to solve the problem is to use a Puppetfile.

If you know what a Ruby gemfile is, you can guess what a Puppetfile is. If you don't, think of a very simple list declaring the modules that a node should get, including ways to get those modules. Like this:

forge 'forge.puppetlabs.com'
