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.

Migrating your Terraform configuration to Terraform 0.13

Officially released in May 2019, version 0.12 of Terraform has brought many new features to the language, but also changes, and during this summer 2020, the new Terraform version 0.13 has been released, also providing new features and some changes.

We must take these changes into account before we upgrade the code.

In this recipe, we will discuss how to verify that our Terraform configuration is compatible with version 0.12. After that, we will learn how to migrate our Terraform configuration from version 0.11 to version 0.12 and then to version 0.13.

Getting ready

Before migrating your code from version 0.11 to the latest version (currently 0.13), you will need to have code that works with the latest version of Terraform 0.11, which is 0.11.14. You can download this version from

It is important to know that if your Terraform configuration is in version 0.11, it is not possible...
