Description

This book is based on Puppet Version 5 which contains all the major concepts of Puppet Automation in a very straightforward and easy-to-understand way. We start by building a strong foundation to get familiar with Automation and Configuration Management. For this we have presented a simple case study to prove why Automation is a must in IT. The book talks about how to setup Puppet Master on CentOS and Ubuntu (two different Linux-based Operating Systems), Setup and configure Puppet Agents/Nodes, Puppet Certification Management, Puppet Architecture. Until this level, you will be in a position to install, configure, and run your own independent Puppet environment.
