OpenTofu: Open Source Infrastructure as Code

by Shriira Press

OpenTofu is an open-source infrastructure-as-code tool, governed under the Linux Foundation, that lets you declare cloud and platform resources in configuration files and bring them into being with a single workflow. Born as a community fork of Terraform after its license changed, OpenTofu stays a drop-in, permanently open tool while pushing its own features forward. This book takes you from the problem of managing infrastructure by hand to a working command of the whole system: the HCL configuration language, the provider plugin model that talks to thousands of APIs, the state file that remembers your infrastructure, the plan-and-apply workflow built on a dependency graph, modules for reuse, and OpenTofu's own additions — client-side state encryption, early evaluation, and dynamic providers.
