عرض عملي: تراجع آلي عند فشل فحص الصحة

خطوة بخطوة

1. Show the pipeline promoting orders image 3f2a9c1 from staging to production with a rolling strategy.
2. Deploy a deliberately broken version whose readiness endpoint fails.
3. Planned mistake: the readiness probe returns 200 always, so the broken version takes traffic. Fix: make readiness check real dependencies and add a post-deploy smoke test.
4. Watch the rollout halt and roll back automatically (for example kubectl rollout undo triggered by the pipeline, or the rollout tool's analysis).
5. Review the timeline: detection time, rollback time, and the user impact on the dashboard.
