Description
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!This course includes topics such as;Overview of the data management problemIntroduction to Hiera, the lookup sub-system of PuppetConfiguring HieraBuilding dynamic lookup hierarchiesUsing facts and variables in Hiera dataIn-data Hiera functionshow to use puppet lookup from the command lineThe lookup puppet functionHow to use automatic data binding to resolve class parametersData merging and cascadingData-in-modules to replace the legacy 'params.pp' patternSecuring sensitive data with Hiera-Eyaml
Who this course is for
Puppet users wishing to further understand Hiera and data separation,Systems engineers and admins who use Puppet to manage their deployments,People with some Puppet experience looking to ramp up their knowledge,Users familar with earlier versions of Hiera and Puppet that want to get up to speed with the latest features
