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.

Destroying infrastructure resources

As we have said many times in this book, IaC allows the rapid provisioning of infrastructure.

Another advantage of IaC is that it allows a quick build and the cleaning up of resources that have been provisioned.

Indeed, we may need to clean up an infrastructure for different reasons. Here are a few examples:

  • We destroy an infrastructure with a view to rebuild it better in accordance with new specifications.

  • We provide an infrastructure that is called on demand, which means it is temporary for a specific need (such as to test a new feature or a new branch of the application). And this infrastructure must be capable of being built and destroyed quickly and automatically.

  • We want to remove an unused infrastructure and, at the same time, no longer pay for it.

In this recipe, we will discuss how to destroy an infrastructure that has been provisioned with Terraform.

To get started, we are going to provide an infrastructure in Azure that...
