An in-depth guide to everything Terraform, complete with newly established best practices and experienced insights into Infrastructure as Code.

Terraform and its open-source fork OpenTofu’s “Infrastructure as Code (IaC)” approach has redefined the way you manage your infrastructure. Its premise is simple-yet-awesome: provision, update, scale, and replicate your infrastructure with the same ease as your application code. In Terraform in Depth, you’ll discover absolutely everything you need to automate and manage your infrastructure with just a few lines of code.

Inside Terraform in Depth, you’ll learn how to:

• Understand and write basic Terraform code
• Avoid vendor lock-in with the open source OpenTofu
• Switch between OpenTofu and Terraform as needed
• Construct continuous integration and continuous delivery (CI/CD) pipelines for Terraform
• Organize Terraform projects and modules for team-based, production use
• Develop and test robust Terraform modules
• Create custom Terraform providers

Terraform in Depth is fully up to date with the latest versions, standards, and approaches of Terraform and OpenTofu. Complete and comprehensive, its one-stop approach covers everything from Terraform and OpenTofu’s absolute basics all the way to advanced production uses. Every technique is illustrated with the kind of real-world examples infrastructure engineers encounter every day.

About the technology:

Terraform and its open-source fork OpenTofu practically eliminate manual infrastructure configuration. With the Terraform infrastructure management tool, even complex operations that used to require kludgy scripts and time-sucking tinkering can be created, managed, and shared as an organized codebase. Master Terraform, and you’ll be able to update a fleet of machines with just a few lines of code.

The CLI is very heavily entwined with Terraform itself. The Terraform core is built into the CLI and can only be accessed by the CLI. CI/CD systems that run Terraform, such as HCP Terraform or Spacelift, are built around either the Terraform or OpenTofu CLI and call it directly. This differs from other languages like Go or C where you can compile code, but it is similar to interpreted languages such as Python or Node where you need a tool to run the programs. For most developers, the CLI is going to be used extensively even if they also have CI/CD systems available. This book includes examples using the CLI as new topics are introduced.

About the book:

Terraform in Depth teaches Terraform techniques and Infrastructure as Code (IaC) practices that you can use to deploy and manage applications in the cloud or your on-prem data center. Each chapter includes interesting hands-on examples, such as creating a flexible Terraform module and debugging Terraform plans. You’ll quickly learn to define your infrastructure with Terraform. Then, you’ll dive into advanced applications, including CI/CD pipelines, creating tools for documentation and security, and Terraform code management.

What's inside:

• Understand and write basic Terraform code
• Avoid vendor lock-in with OpenTofu
• Construct CI/CD pipelines
• Develop and test Terraform modules
