Writing and Using Modules: Input/Output Contracts, Registry Modules, Versioning and Dynamic Sources
A module is a repeated group of resources that offers a contract through its variables and outputs; moving resources into a module means deleting and recreating them unless you use moved blocks. We move the API into a bookstore-service module and the Web App into bookstore-webapp, see why prevent_destroy did not protect anything, download and inspect an Azure Verified Module, and try version pinning, const variables in module sources and deprecated inputs and outputs from Terraform 1.15.
