This online instructor led training course provides the knowledge and skills to utilize Puppet, an open source software configuration management and deployment tool. In this course students will learn key topics including the what Puppet is, its supported platforms, Puppet OSS and Puppet Enterprise, Puppet concepts, building a lab, using different types of resources, Hiera lookups, and more.
Overview
Skills Learned
After completing this online training course, students will be able to:
Understand what Puppet is
Know the differences between Puppet OSS and Enterprise
Understand Puppet concepts, including run process, declaritive programming, puppetdb, and more
Be able to build a lab by installing the Puppet master and the agent
Understand classes and ordering
Better understand Puppet resources and types
Understand Hiera lookups
Be able to describe Puppet at scale
Understand how to avoid the common Puppet ordering loops
Be able to install Puppet Enterprise and understand the Puppet Enterprise Console
This course is intended for sysadmins, SREs, DevOps engineers or similar who manage Windows, Linux, or Unix infrastructure and want to learn about Puppet and how it can be utilized to automate their infrastructure.
None, but we recommend that students have experience working with deploying applications on their operating system and familiarity with Ruby.
