Overview of this book

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. It focuses on how to set up continuous integration for the infrastructure code. The readers will be able to use Terraform to build, change, and combine infrastructure safely and efficiently.

The rapid development of Terraform

Terraform was first released just a couple of years ago, and it still hasn't reached a major version. It gains more and more in popularity; it grows like crazy, actually, and changes rapidly.

The book you are reading was started with Terraform 0.7.7. It was finished and updated to Terraform 0.8. Even between minor versions, from 0.7.7 up to 0.7.13, there were many small changes that made some code deprecated and some code broken. However, Terraform 0.8 introduced conditionals, as well introducing proper dependencies on modules, which made big chunks of code simply irrelevant now.

With an ever-growing number of contributors and, as a result, the size of the code base, number of providers, and so on, it can be hard to catch up with the latest changes. Keep this in mind when starting to use Terraform: you have to be ready to deal with incompatible changes, with new features appearing, and old ones going away. It is true for every open source project. It is especially...
