Overview of this book

<p>Chef is a configuration management tool that turns IT infrastructure into code. Chef provides tools to manage systems at scale. With this book, you will learn how to use the same tools that companies such as Facebook, Riot Games, and Ancestry.com use to manage and scale their infrastructure.</p> <p>This book takes you on a comprehensive tour of Chef's functionality, ranging from its core features to advanced development. You will be brought up to speed with what's new in Chef and how to set up your own Chef infrastructure for individuals, or small or large teams. Once you have the core components, you will get to grips with bootstrapping hosts to then develop and apply cookbooks. If you want to fully leverage Chef, this book will show you advanced recipes to help you handle new types of data providers and resources. By the end of this book, you will be confident in how to manage your infrastructure, scale using the cloud, and extend the built-in functionality of Chef itself.</p>

Summary


RSpec with ChefSpec extensions provides us with incredibly powerful tools to test our cookbooks and recipes. You have seen how to develop basic ChefSpec tests for your recipes, organize your spec tests inside of your cookbook, execute and analyze the output of your spec tests, and simulate the execution of your recipes across multiple platforms.

In future chapters, we will learn some more advanced testing mechanisms such as mocking and stubbing external services such as search and data bags. Adding testing to your development cycle allows you to feel confident in the correctness of your recipes, which is a critical step towards automating the management of your infrastructure.

Now, let's take a look at how we will build a cookbook to complement a web application so that we can see the full cycle of developing an application and deploying it using Chef.
