Writing High Quality Terraform Modules for Exponential Organizations
summary
Shows a reusable aws vpc module with main, variables, outputs and an examples directory and a GitHub repo; uses a count attribute to create subnets and enforces types and descriptions so configs fail fast (no defaults for required inputs). Generates README with terraform-docs, runs an automated CI/CD pipeline that applies examples and destroys them, and practices semantic versioning with tags (demonstrates a breaking change where a required variable becomes optional).
