Harden feature flag rollback playbook
Hard DevOps Basics arena: kill switches, scoped rollout, metrics gates, and fast rollback commands
Log in and clear the lower tiers to unlock this mission.
Missing prerequisites: devops-easy-feature-flag-rollback
A new checkout feature increases errors for one region and must be disabled without redeploying. You are working inside a deployment operations lab, and the arena only clears when the result is safe, deterministic, and explainable.
Learn to apply kill switches, scoped rollout, metrics gates, and fast rollback commands in a deployment operations lab while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates kill switches, scoped rollout, metrics gates, and fast rollback commands
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution
