Building Terraform Modules

Overview

Build reusable, production-ready Terraform modules with proper variable definitions, outputs, validation rules, documentation, and examples. Generate modules following HashiCorp's standard module structure for AWS, GCP, and Azure resources with security best practices, tagging conventions, and lifecycle management.

Prerequisites

Terraform 1.0+ installed (terraform version)

Cloud provider credentials configured for the target platform

Understanding of the infrastructure resources the module will manage

Familiarity with HCL syntax and Terraform module conventions

terraform-docs installed for automated documentation generation (optional)

Instructions

Define the module scope: determine which cloud resources the module manages and its input/output contract

Create the standard module file structure: main.tf, variables.tf, outputs.tf, versions.tf, locals.tf

Write versions.tf with required_version and required_providers blocks pinned to stable versions

Define input variables in variables.tf with descriptions, types, defaults, and validation rules

Implement resources in main.tf using variables for all configurable values; use locals for computed values

Add meaningful outputs in outputs.tf for resource IDs, ARNs, endpoints, and connection strings

Implement security defaults: encryption enabled, public access blocked, least-privilege IAM, logging enabled

Create an examples/ directory with at least one complete usage example showing module invocation

Generate documentation with terraform-docs markdown table . > README.md

Validate the module with terraform init && terraform validate and test with terraform plan using the example

Output

Module files: main.tf, variables.tf, outputs.tf, versions.tf, locals.tf

Example usage in examples/basic/main.tf with realistic variable values

Auto-generated README.md with inputs, outputs, and usage documentation

.terraform-docs.yml configuration for documentation generation

Optional: test files using Terratest or terraform test (HCL-based)

Error Handling

Error

Cause

Solution

variable validation failed

Input value does not meet validation rule

Check the validation block in variables.tf; adjust the value or the validation regex

provider not found

Missing or wrong provider source in versions.tf

Add the provider to required_providers with correct source and version constraint

circular dependency

Resources referencing each other in a loop

Refactor to break the cycle; use depends_on or separate into sub-modules

output references undeclared resource

Typo in resource name or resource removed

Verify resource names in main.tf match output references exactly

module source not found

Incorrect module path or registry reference

Verify the source path is relative (e.g., ./modules/vpc) or a valid registry address

Examples

"Build a Terraform module for an AWS VPC with configurable CIDR, public/private subnets across 3 AZs, NAT gateway, and flow logs."

"Create a GCP Cloud Run module with custom domain, IAM bindings, and auto-scaling configuration as input variables."

"Generate a Terraform module for an S3 bucket with versioning, encryption, lifecycle rules, and access logging, with all settings as optional variables with secure defaults."
