Multiple Files
At some point, your main.tf may become too large to stay readable. You can split such a file into several files.
Multiple Files
When invoking any command that loads the Terraform configuration, Terraform loads all configuration files within the directory specified in alphabetical order.
The exact names and order aren’t important to Terraform. The order of variables and resources defined within the configuration doesn’t matter. Terraform configurations are declarative, so references to other resources and variables do not depend on the order they’re defined.
Therefore, you should structure the files to make it the most readable and maintainable for developers and operators.
Module Breakdown
It’s common to define providers, input variables, and output values in their files. Execute the following breakdown:
- Move two provider definitions to a new
providers.tffile - Move variables definitions to
variables.tf - Move outputs to
outputs.tf
Test your refactoring by running terraform apply.
Checkpoint
Run terraform apply and make sure that no changes are required. The file structure should have no impact on actual cloud resources.
