In this example, Terraform will search for a module in the Terraform registry that matches the given string. Next, we can use the module in Terraform configurations. This provides a transparent and smooth workflow experience with externally sourced modules. Terraspace will source example from app/modules and s3 and ec2 from vendor/modules.. All the configurations you’ve written so far have technically been modules, although not particularly interesting ones, since you deployed them directly (the module in the current working directory is called the root module). Terraform is an open source tool for managing infrastructure as code. A Terraform module is only a part of a solution to a particular problem, and it is likely that the problem may change in the future. If you omit it, a child module inherits all of the default provider configurations from its parent module.
