My Favorite Vagrantfile (CentOS 6 with Librarian Puppet)

librarian.pp

# Universal Configuration
# These configure the Vagrant VM so it can be used with the Puppet modules.

stage { 'pre':
  before => Stage['main'],
}

# Install any dependencies
class dependencies {
  package { ['git']:
    ensure => latest,
  }

  package { 'librarian-puppet':
    ensure => '0.9.14',
    provider => 'gem'
  }
}

class { "dependencies":
  stage => pre,
}

exec {"librarian-puppet init":
  path => "/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/vagrant/bin",
  cwd => "/vagrant/puppet",
  user => "vagrant",
  group => "vagrant",
  creates => "/vagrant/puppet/Puppetfile",
  environment => "HOME=/home/vagrant",
  require => [ Package["librarian-puppet"], Package["git"] ],
}

exec { "librarian-puppet install":
  path => "/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/vagrant/bin",
  cwd => "/vagrant/puppet",
  user => "vagrant",

  require => [ Exec["librarian-puppet init"] ],
}
