# Terraform Module Library Production-ready Terraform module patterns for AWS, Azure, GCP, and OCI infrastructure. ## Purpose Create reusable, well-tested Terraform modules for common cloud infrastructure patterns across multiple cloud providers. ## When to Use - Build reusable infrastructure components - Standardize cloud resource provisioning - Implement infrastructure as code best practices - Create multi-cloud compatible modules - Establish organizational Terraform standards ## Module Structure ``` terraform-modules/ ├── aws/ │ ├── vpc/ │ ├── eks/ │ ├── rds/ │ └── s3/ ├── azure/ │ ├── vnet/ │ ├── aks/ │ └── storage/ ├── gcp/ │ ├── vpc/ │ ├── gke/ │ └── cloud-sql/ └── oci/ ├── vcn/ ├── oke/ └── object-storage/ ``` ## Standard Module Pattern ``` module-name/ ├── main.tf # Main resources ├── variables.tf # Input variables ├── outputs.tf # Output values ├── versions.tf # Provider versions ├── README.md # Documentation ├── examples/ # Usage examples │ └── complete/ │ ├── main.tf │ └── variables.tf └── tests/ # Terratest files └── module_test.go ``` ## AWS VPC Module Example **main.tf:** ```hcl resource "aws_vpc" "main" { cidr_block = var.cidr_block enable_dns_hostnames = var.enable_dns_hostnames enable_dns_support = var.enable_dns_support tags = merge( { Name = var.name }, var.tags ) } resource "aws_subnet" "private" { count ...
