Smoke test fails after canary deployment. Design the automated rollback.
Tests self-healing pipeline design: freeze canary traffic, auto-redeploy the last good release, verify rollback health, and keep failed pods for forensics. Red flag: requiring manual approval or in-place fixes instead of an atomic rollout swap.
Tests production safety automation: immediately halt canary traffic shift, atomically redeploy the last known good release without human approval, run post-rollback health checks to confirm the prior version is still viable, preserve the failed environment for root-cause analysis, page on-call with runbook links, and emit pipeline metrics. Red flag: suggesting manual gates, database schema rollbacks, or mutating live containers instead of performing a clean, fully automated rollout swap.
