Terraform Variable Anti-Patterns: Why Your Code Still Runs but Your Graph is Failing

In this lesson, we explore why "valid" HCL doesn't always equal "good" infrastructure. Variable anti-patterns are subtle distortions that weaken the Terraform dependency graph. They don't cause syntax errors; they cause maintenance debt, security leaks, and architectural fragility. We break down the four most common distortions: The Disguised Constant: When a variable pretends to be flexible but hides a static value. Variables as Wiring: When strings replace resource references, breaking the flow of meaning through the graph. Secrets by Convention: Why naming a variable "password" doesn't protect your data, but metadata does. Hidden Structure: The cost of using opaque maps and generic objects instead of explicit types. Key Mental Model: Variables should expose uncertainty. References should expose relationships. When we use variables to hide either, the system still runs, but it understands less.
