Take your Puppet knowledge to the next level by mastering Hiera

Puppet is a powerful tool for managing infrastructure and has been helping people with config management for over a decade. 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.

Hiera is much more than a key value store and the latest Hiera 5 release contains a whole host of features designed to make managing large amounts of data efficient and easy.

This is a course aimed at people who have already had exposure to Puppet and want to further expand their knowledge by mastering Hiera. This course will leave you with all the tools you need to manage even the most complex of infrastructures, write re-usable and sharable Puppet modules and reduce spaghetti code by learning about data separation and hierarchical lookups.

The topics in this course cover all the latest cutting edge and newly released features that we see in Hiera 5 and Puppet 6, don’t get left behind!
