Puppet 4: Hiera, the Single Source of Truth

By Andrew Mallett
Hiera allows your code to be abstracted from the implementation. More simply, you can remove much of the logic from your code and let it be replaced with Hiera lookups. This course will teach you how to do just that.

Description

Throughout this series of Puppet 4 courses, the complexity of the NTP module has been building up. Now, you can start to simplify the module by removing components and adding Hiera. In this course, Puppet 4: Hiera, the Single Source of Truth, you'll be refactoring the NTP module to make use of Hiera in replacement of some of the Puppet logic. First, you'll learn how to write YAML files. Next, you'll learn how to configure and test Hiera. Finally, you'll learn the fault-finding Puppet applications. By the end of this course, you'll be able to implement modules using Hiera efficiently and effectively.
