Automatic Prometheus metrics discovery with Docker labels

Akvorado , a network flow collector, relies on Traefik , a reverse HTTP proxy, to expose HTTP endpoints for its Docker Compose services. Docker labels attached to each service define the routing rules. Traefik picks them up automatically when a container starts. Instead of maintaining a static configuration file to collect Prometheus metrics , we apply the same approach with Grafana Alloy .
