How to Use Optional Arguments in Terraform Variables

This article discusses the use of optional arguments in Terraform variables to enhance the quality of your code. These optional parameters include type, default, description, validation, sensitive, and nullable. Each parameter serves a specific purpose such as specifying data types, providing default values, adding descriptions for better readability, validating variable values, treating variable values as sensitive information, and controlling whether a value can be set to null. Using these optional parameters can make your Terraform configurations more robust and user-friendly. The article also encourages exploring Spacelift for managing Terraform infrastructure and offers an open-source alternative called OpenTofu.
