Terraform Cookbook

By: Mikael Krief

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.

Detecting resources deleted by the plan command

One of the key features of Terraform is the possibility to visualize a preview of changes in advance of their application to a given piece of infrastructure with the terraform plan command.

We have often discussed in this book displaying a visualization of changes in the terminal, but what we see less often is how to automatically evaluate and analyze the results of the terraform plan command.

In this recipe, we will see how to analyze the results of the terraform plan command.

Getting ready

For the application of this recipe, we need to have the jq tool installed, available for download for all platforms from

In this recipe, we will use jq on Windows with PowerShell, but all steps will be identical on other OSes.

The Terraform configuration used is available at, and we must run it on our infrastructure beforehand.
