Module Design Patterns
Create reusable, composable Terraform modules for consistent infrastructure patterns.
Terraform module composition and registry sources
Well-designed modules encapsulate infrastructure patterns and promote reuse across projects and teams. We follow Terraform module best practices for maintainability and flexibility.
Module design principles:
- Single Responsibility - Each module handles one logical component
- Sensible Defaults - Work out of the box with minimal configuration
- Flexible Inputs - Allow customization without forking
- Clear Outputs - Expose values needed by dependent resources
Key Concepts
- Use semantic versioning for module releases
- Document all variables and outputs
- Include examples for common use cases
- Test modules with Terratest or similar
- Publish to private registry for team access
