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.

It's been another long chapter to digest and there has been a ton of new things to learn and try. You started by learning Git and how to organize work though Git branches, remote repositories, and code review. You learned how to easily store secrets in a setup like this with git-crypt. After this, we took a look at the remote storage of state files for Terraform, and at various methods to split the Terraform code inside the organization.

As part of this, we wrote our first completely remote Terraform module, refactored the whole IAM and VPC management away from the main repository, and connected it all nicely in a small, and clean template. To avoid conflicts and to better structure the infrastructure work, we set up the Terragrunt utility and learned how to use it too.

We took the whole infrastructure as code idea to the extreme by introducing a complete Continuous Integration pipeline for the infrastructure (and learned a bit of GitLab CI). As a final battle, we even created a real...
