Description: The default configuration value in Terraform refers to the predefined value assigned to a parameter within a module or resource. This value is used when the user does not provide a specific input for that parameter when executing the configuration. Default values are essential for simplifying the user experience, as they allow resources to be configured with a basic setup without needing to specify every detail. Additionally, they facilitate the reuse of modules, as developers can establish common configurations that apply to multiple instances of a resource. In Terraform, default values are defined in the variable block, where a value can be specified that will be used if no other is provided. This not only improves code readability but also helps prevent errors by ensuring that there is always a valid value in use. In summary, the default configuration value is a key feature that optimizes infrastructure management as code, allowing users to focus on customizing specific aspects without losing sight of basic functionality.
