05 ANSWER-SAFE INCIDENT BRIEFS
Terraform incident practice
Practice remote-state, provider, resource-address, dependency-graph, and refactor incidents without risking a real cloud account.
WHY THIS TRACK MATTERS
Debug the system, not the first plausible theory.
The dangerous Terraform mistake is treating a surprising plan as permission to apply. Good operators reconcile configuration, state, provider behavior, and real infrastructure first.
- Protect and reconcile Terraform state
- Interpret destructive or surprising plans
- Refactor infrastructure without replacement
