Overview of this book

Terraform is a highly sought-after technology for orchestrating infrastructure provisioning. This book is a complete reference guide to enhancing your infrastructure automation skills, offering up-to-date coverage of the HashiCorp infrastructure automation certification exam. This book is written in a clear and practical way with self-assessment questions and mock exams that will help you from a HashiCorp infrastructure automation certification exam perspective. This book covers end-to-end activities with Terraform, such as installation, writing its configuration file, Terraform modules, backend configurations, data sources, and infrastructure provisioning. You'll also get to grips with complex enterprise infrastructures and discover how to create thousands of resources with a single click. As you advance, you'll get a clear understanding of maintaining infrastructure as code (IaC) in Repo/GitHub, along with learning how to create, modify, and remove infrastructure resources as and when needed.

Chapter 6: Terraform Workflows

In the previous chapter, we discussed the Terraform command-line interface (CLI) and saw some outputs from Terraform commands.

In this chapter, we will take a look at a core workflow of the Terraform tool, which involves creating a Terraform configuration file (write), previewing the changes (plan), then finally committing those changes to the target environment (apply). Once we are done with the creation of the resources, we might be required to get rid of infrastructures (destroy). In a nutshell, we are planning to cover Terraform core workflows, which mainly consist of terraform init, terraform plan, terraform apply, and terraform destroy operations, and the respective subcommands and their outputs. Understanding Terraform workflows will help you to provision and update infrastructure using Terraform infrastructure as code (IaC). We will also be explaining the integration of Terraform workflows with major cloud providers such as Azure. Moving...
