PuppetConf 2014

The OpenStack Infrastructure Team has open sourced their entire Puppet configuration. The team keeps all public files in a git repository and handles changes via a code review system that anyone in the project can propose changes to. Private data is managed in Hiera by a core, trusted team of contributors who come from multiple companies and organizations.

This talk will walk through how they've structured our public repository, improvements made this year during a restructuring project and review the work of some other projects who have done similar things with their own Puppet configurations, including Debian and Mozilla.
