Getting Started with Terraform

By: Kirill Shirinkin

Overview of this book

Terraform is a tool used to efficiently build, configure, and improve production infrastructure. It can manage 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 complete management of infrastructure with Terraform, starting with the basics of using providers and resources. This book 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. It finishes with the complete workflow of managing a production infrastructure as code – this is achieved with the help of version control and continuous integration. At the end of this book, you will be familiar with advanced techniques such as multi-provider support and multiple remote modules.

It's been a lot of information in this chapter, but we finally know all the possible ways to supply configuration to Terraform templates. Let's recap what you learned.

You learned how to use variables in Terraform: what kind of variables we can use and how we can provide them interactively, inline, with environment variables and variable files. We also discovered data sources: a relatively new concept in Terraform that allows to get read-only data. While being still perhaps a bit too new, we found few applications for this concept. Then, you learned how to generate configuration files with the template_file data source and on top explored multiple other providers, all simplifying our configuration efforts. In the end, we even took a brief look into what Consul is and how it works with Terraform.

But Consul is not the only tool that you will want to use with Terraform. As Terraform is just a one utility in your infrastructure tool chain, you might be wondering how to connect it with...
