Developer pushes code to GitHub

↓

GitHub Actions builds + scans the image

↓

Docker image pushed to registry

↓

ArgoCD detects manifest change in Git

↓

ArgoCD syncs to k3s Kubernetes cluster

↓

Prometheus scrapes metrics from all pods

↓

Grafana visualizes — AlertManager fires on anomalies

↓

Loki aggregates all logs
