Terraform is a tool used to efficiently build, configure, and improve the production infrastructure. It can manage the existing infrastructure as well as create custom in-house solutions. This book shows you when and how to implement infrastructure as a code practices with Terraform. It covers everything necessary to set up the complete management of infrastructure with Terraform, starting with the basics of using providers and resources. It is a comprehensive guide that begins with very small infrastructure templates and takes you all the way to managing complex systems, all using concrete examples that evolve over the course of the book. The book ends with the complete workflow of managing a production infrastructure as code—this is achieved with the help of version control and continuous integration. The readers will also learn how to combine multiple providers in a single template and manage different code bases with many complex modules.

Baking images with Packer

Packer was released back in 2013 with the goal of simplifying, automating, and codifying the image creation process. It removes all the pain from baking images for different platforms by replacing many manual steps with a single JSON template fed to the CLI. It is written in the Go programming language, just like Terraform. Installing it is a piece of cake--just download the archive for your operating system from and extract the binary to a directory available in your $PATH environment variable. Then, verify your installation:

$> packer -v0.12.0

You are all set up to bake images! To do so, just run packer build my_template.json. It won't work, of course, because we don't have a template yet. Create the base.json file and let's start filling it in. Our goal is to bake a CentOS 7 AMI with all packages updated and Puppet installed.

The only required section for the template is the builders array definition. Builders are configuration...
