Description
Puppet is a powerful tool for managing infrastructure and has been helping people with config management for over a decade.Â One of Puppet's most valuable features that sets it apart from other tools is how it is able to manage configuration data using Hiera.

Overview of the data management problem
Introduction to Hiera, the lookup sub-system of Puppet
Configuring Hiera
Building dynamic lookup hierarchies
Using facts and variables in Hiera data
In-data Hiera functions
How to use puppet lookup from the command line
