Purpose of Variables in Terraform Variables prevent repetitive hardcoding of values in Terraform configuration files. They reduce errors due to inconsistent value entries across multiple resources. Simplify updating environment-specific configurations (e.g., changing from dev to stage). Types of Variables Based on Purpose Input Variables: Accept values from users or other sources.

State that survives a docker compose down is one of those things you don't think about, until your test suite needs it, your local dev needs it, and your CI pipeline absolutely doesn't.
