Variables and Outputs

The Terraform language includes a few kinds of blocks for requesting or publishing named values.

Input Variables serve as parameters for a Terraform module, so users can customize behavior without editing the source.
Output Values are like return values for a Terraform module.
Local Values are a convenience feature for assigning a short name to an expression.
