An in-depth guide to everything Terraform, complete with newly established best practices and experienced insights into Infrastructure as Code. Terraform, and its new open source fork OpenTofu, practically eliminates manual infrastructure configuration, making it possible to script and automate almost every aspect of system management and administration. Its "Infrastructure as Code (IaC)" approach has a simple-yet-awesome premise: 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 with 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 book Terraform in Depth teaches you to effectively create and manage your infrastructure as Terraform code. Inside, you'll find essential insights into modern Terraform, including newly established patterns, best practices, and methods for empowering your development team with IaC. Each chapter is fully illustrated with hands-on examples, such as creating a flexible Terraform module to launch EC2 instances and debugging complex Terraform plans.
