Observability with Prometheus, Grafana, and Flagger Metrics

No canary deployment strategy is complete without robust observability. In this part, you’ll integrate Prometheus and Grafana into your EKS cluster, configure Flagger to emit canary-specific metrics, and visualize deployment progress in real time. You’ll also enable alerting and telemetry that help diagnose rollout issues and reduce time-to-recovery in case of deployment failures.
