Overview
Puppet training teaches participants how to install and administer the Puppet master and agent (client) applications in a RHEL/CentOS 7 environment. Participants learn how to write and apply resource definitions, the key part of Puppet that allows an administrator to synchronize environments easily and uniformly.
Objectives
At the end of Puppet training course, participants will be able to
- Install and configure Puppet servers and agents
- Create and modify manifests that contain resource definitions
- Create and modify classes, modules, node definitions, and environments
- Apply manifests, classes, nodes, and environments
- Extend Puppet with functions
- Use (and extend) Facter facts
- Generate basic reports
- Use the MCollective and Hiera 5 tools
- Design a ‘best practice’ strategy for using Puppet capabilities
Prerequisites
It is assumed that participants are working systems administrators with some scripting knowledge (bash, ksh, Perl or Python) and an understanding of the various system tasks relating to setting up and supporting Linux systems.
