Overview of this book

HashiCorp Configuration Language (HCL) has changed how we define and provision a data center infrastructure with the launch of Terraform—one of the most popular and powerful products for building Infrastructure as Code. This practical guide will show you how to leverage HashiCorp's Terraform tool to manage a complex infrastructure with ease. Starting with recipes for setting up the environment, this book will gradually guide you in configuring, provisioning, collaborating, and building a multi-environment architecture. Unlike other books, you’ll also be able to explore recipes with real-world examples to provision your Azure infrastructure with Terraform. Once you’ve covered topics such as Azure Template, Azure CLI, Terraform configuration, and Terragrunt, you’ll delve into manual and automated testing with Terraform configurations. The next set of chapters will show you how to manage a balanced and efficient infrastructure and create reusable infrastructure with Terraform modules. Finally, you’ll explore the latest DevOps trends such as continuous integration and continuous delivery (CI/CD) and zero-downtime deployments. By the end of this book, you’ll have developed the skills you need to get the most value out of Terraform and manage your infrastructure effectively.

Before you start writing the Terraform configuration file, it is necessary to install and configure a local development environment. This development environment will allow Terraform's configuration file to be written and validated as it is developed.

In the recipes in this chapter, we will learn how to download and install Terraform manually on a Windows machine, as well as how to install it using a script on Windows and Linux. We will also learn how to use Terraform in a Docker container before learning how to migrate the Terraform configuration written in version 0.11 to version 0.13.

In this chapter, we'll cover the following recipes:

  • Downloading and installing Terraform manually
  • Installing Terraform using a script on Linux
  • Installing Terraform using a script on Windows
  • Executing Terraform in a Docker container
