New Guides for Terraform Modules

Over the last few years, one of the most popular topics on our YouTube channel, in person at conferences, and in other discussions has been writing, using, refactoring, and collaborating on complex configurations using Terraform modules. Modules are a key part of writing maintainable, shareable Terraform configurations.

Use and create your first Terraform modules by following our new step-by-step command-line guides in the Learn modules track.
