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.

Building CI/CD for Terraform modules in Azure Pipelines

Throughout this chapter, we have studied recipes for creating, using, and testing Terraform modules. On the other hand, in the Using a private Git repository for sharing a Terraform module recipe in this chapter, we discussed the possibility of using a private Git repository, such as Azure DevOps, to store and version your Terraform modules.

In a DevOps context, when the module is created and the tests have been written, we need to create a DevOps CI/CD pipeline that will automate all of the steps we discussed for the execution of the tests that we performed manually.

There are many CI/CD pipeline platforms; in this recipe, we will see the implementation of a CI/CD pipeline to automate the tests and the publication of a Terraform module in Azure Pipelines.

Getting ready

To start this recipe, we must first create a Terraform module and tests with Terratest. For this, we will use the same module and its tests that we created in the...
