Grafana, Prometheus, and Loki Stack

Grafana, Prometheus, and Loki Stack

Full observability for your Docker infrastructure in one command. Prometheus collects metrics, Loki aggregates logs, and Grafana visualizes everything — with datasources pre-wired and starter dashboards ready on first boot.

What Is Included

• Prometheus — Metrics collection with Node Exporter and cAdvisor pre-configured as scrape targets
• Loki — Log aggregation backend with Grafana Alloy shipping all container logs automatically
• Grafana — Pre-provisioned with both Prometheus and Loki datasources; no manual setup required
• Starter Dashboards — Node overview, Docker host resources, and container logs dashboard imported on first boot

How It Works

• Run docker compose up -d — all five services start and health-check each other
• Grafana datasources are provisioned automatically via the provisioning/datasources directory
• Dashboards are imported automatically via provisioning/dashboards
• Alloy is configured to collect logs from all running containers via the Docker socket

What You Get

• docker-compose.yml — all five services with named volumes and health checks
• prometheus.yml — scrape config with Node Exporter and cAdvisor targets
• loki-config.yaml — Loki storage and retention configuration
• alloy-config.alloy — Docker log collection via socket
• grafana/provisioning/ — datasource and dashboard provisioning files
• grafana/dashboards/ — three starter JSON dashboards
• .env.example and README.md
