Puppet is and has been the de-facto configuration management in Linux and Unix systems, and with Puppet 4, it is even bigger and stronger. This course teaches you how to create the best streamlined Puppet code onto Classes and Modules.
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.

Hi everyone and welcome, my name is Andrew Mallett, otherwise known as the theurbanpenguin. I hope you are ready for my 2nd Puppet course You know that I work in the UK with my own Linux training and consultancy, 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 7 0r 8 years ago to complete classroom setups and still use it today In this course you will learn how to streamline you code into modules making it easier to maintain and use We continue with the NTP theme from the Language Essentials course and break our code in to classes and modules looking at 1. Module structure 2. Declaring Classes with and without parameters 3. Creating Custom Resource types in Ruby By the end of the course you will be able to create Puppet modules containing multiple classes that have the flexibility of taking input at runtime You will need some basic knowledge of Linux and understanding of Puppet gained from the Puppet 4: Language Essentials course
