Description: A module output variable in Terraform is a mechanism that allows modules to return specific values after execution. These variables are fundamental for code modularity and reuse in infrastructure as code (IaC). By defining an output variable, users can extract relevant information, such as IP addresses, resource names, or any other data generated during the module’s execution. This not only facilitates the integration of different modules but also enhances the clarity and organization of the code, allowing developers to better understand how the various components of their infrastructure interact. Output variables are defined in the module’s configuration file and can be referenced in other configurations or in the main Terraform configuration, enabling more efficient resource management. In summary, module output variables are a key tool for creating scalable and maintainable infrastructures, promoting collaboration and code reuse in Terraform projects.
