Rollback

​

Triage

• availability is degraded
• error rate spikes
• a deployment introduces incorrect behavior with no safe runtime mitigation

​

Application rollback (Kubernetes)

kubectl rollout history deployment/api -n materi
kubectl rollout undo deployment/api -n materi
kubectl rollout status deployment/api -n materi

​

GitOps rollback

1. Revert the deployment commit
2. Allow controller reconciliation
3. Verify health + telemetry

​

Database-aware rollback

• If migrations are backwards compatible, an app rollback is usually safe.
• If migrations are breaking, you need a downgrade plan (or restore) before rolling back the app.

​

Verification checklist

• Health checks pass
• Error rate returns to baseline
• Key dashboards stable
• Incident summary captured
