Description

Organizing your code into modules and classes will make it more usable and maintainable, which will make you more employable. In this course, Puppet 4: Working with Modules and Classes, you'll learn how to organize your code better than ever before. First, you'll learn to transform an NTP manifest into a more usable application, in the form of a module containing classes and defined types. You'll also learn how to create code once and reuse it. Finally, you'll discover how to validate input to parameterized classes. By the end of this course, you'll know how to refactor monolithic, flat Puppet manifests into streamlined modules.

Course Overview
Hello everyone, and welcome. My name is Andrew Mallet, but you might know me as The Urban Penguin. I do hope you're ready for my second Puppet course. You know that I work in the UK and I have my own Linux training and consultancy company, and Puppet has always been my configuration tool of choice as it is also for 8 out of 10 penguin owners who expressed a preference. I started using Puppet seriously about seven or eight years ago. I used it to complete classroom setups, and I'm still using it today. In this course, we're going to learn how you can streamline your code by creating modules, making it easier to maintain and use. We're going to continue with our ntp theme from the Language Essentials course, and we're going to look at how we can break our code into classes and modules. And we'll be taking a look at the module structure, looking at ways that we can create and declare classes, both with and without parameters, and we'll be looking at creating custom resource types in Ruby. Now by the end of this course you're going to be able to create your own modules containing multiple classes, and have the flexibility of being able to take input at run time. Now you are going to need some basic knowledge of Linux and a good understanding of the Puppet language, which you can gain by taking a look at our Puppet 4: Language Essentials course.
