Terraform Cookbook

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.

Debugging the Terraform execution

When we execute Terraform commands, the display output of the console is quite simple and clear.

In this recipe, we will study how to activate the debug mode in Terraform, which will allow us to display more information about its execution.

Getting ready

For this recipe, we will use the Terraform configuration available at

Furthermore, for the purposes of this demonstration, we will run it on a Windows operating system, but the operation is exactly the same on other operating systems.

How to do it…

To activate the debug on Terraform, perform the following steps:

  1. In the PowerShell command-line terminal, execute the following command:
$env:TF_LOG = "TRACE"
  1. Now, we can execute the Terraform workflow commands with display logs activated:
> terraform init
> terraform plan -out=app.tfplan
> terraform apply app.tfplan

How it works…
