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>

Getting started with ChefSpec


In order to get started with ChefSpec, create a new cookbook directory (here it is $HOME/cookbooks/mycookbook) along with a recipes and spec directory:

mkdir -p ~/cookbooks/mycookbook 
mkdir -p ~/cookbooks/mycookbook/recipes
mkdir -p ~/cookbooks/mycookbook/spec

Now you will need a simple metadata.rb file inside your cookbook (here, this will be ~/cookbooks/mycookbook/metadata.rb):

maintainer       "Your name here"
maintainer_email "[email protected]"
license          "Apache"
description      "Simple cookbook"
long_description "Super simple cookbook"
version          "1.0"
supports         "debian"

Once we have this, we now have the bare bones of a cookbook that we can begin to add recipes and tests to.

Installing ChefSpec

In order to get started with ChefSpec, you will need to install a gem that contains the ChefSpec libraries and all the supporting components. Not surprisingly, that gem is named chefspec and can be installed simply by running the following:

gem install...
