terraform-module-library

Build reusable, multi-cloud Terraform modules following IaC best practices.

• Reusable Terraform modules for AWS, Azure, and GCP
• Standardized cloud infrastructure components
• Production-ready IaC patterns across providers

• Use semantic versioning
• Document all variables with descriptions
• Provide usage examples in examples/ directory
• Use input validation blocks
• Output critical attributes for composition
• Pin provider versions in versions.tf
• Test modules with Terratest
• Tag resources consistently

1. 1.Create module structure with main.tf, variables.tf, outputs.tf
2. 2.Define inputs with descriptions and validations
3. 3.Use conditional resources with count/for_each
4. 4.Pin provider versions in versions.tf
5. 5.Test with Terratest in a test directory
6. 6.Compose modules in main.tf using source and inputs
