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.

Working with workspaces in CI/CD

In the Using workspaces for managing environments recipe in Chapter 4, Using the Terraform CLI, we studied the use of some Terraform commands to manage and create workspaces. In Terraform's vision, workspaces make it possible to manage several environments by creating several Terraform state files for the same Terraform configuration.

In this recipe, we will go further with the use of workspaces by automating their creation in a CI/CD pipeline.

Getting ready

The prerequisite for this recipe is to know the Terraform command-line options for the workspaces, the documentation for which is available at

Concerning the CI/CD pipeline, we will implement it in Azure Pipelines, which we have already seen in this chapter, in the Building CI/CD pipelines for Terraform configuration in Azure Pipelines recipe.

The purpose of this recipe is to illustrate a scenario I recently implemented, which is the...
