Chapter 8. Classes, roles, and profiles

Our life is frittered away by detail. Simplify, simplify!

—Henry David Thoreau

In this chapter, you will explore the details of Puppet classes and the distinction between defining a class and declaring a class, and also learn how to use parameters with classes and how to declare appropriate data types for your parameters. You'll learn how to create defined resource types, and how they differ from classes. You'll also see how to organize your Puppet code using the concepts of nodes, roles, and profiles.

John Arundel

John Arundel

John Arundel is a DevOps consultant, which means he helps people build world-class web operations teams and infrastructures and has fun doing it. He was formerly a senior operations engineer at global telco Verizon, designing resilient, high-performance infrastructures for major corporations such as Ford, McDonald's, and Bank of America. He is now an independent consultant, working closely with selected clients to deliver web-scale performance and enterprise-grade resilience on a startup budget. He likes writing books, especially about Puppet (Puppet 2.7 Cookbook and Puppet 3 Cookbook are available from Packt). He also provides training and coaching on Puppet and DevOps, which, it turns out, is far harder than simply doing the work himself. Off the clock, he is a medal-winning, competitive rifle and pistol shooter and a decidedly uncompetitive piano player. He lives in a small cottage in Cornwall, England and believes, like Cicero, that, if you have a garden and a library, then you have everything you need. You may like to follow him on Twitter at @bitfield.
