Farm Control Stack

This folder contains a starter central-control stack for your farm:

• PostgreSQL (operational + business data)
• Mosquitto MQTT (sensor/device messaging)
• Grafana (dashboards/alerts)
• Node-RED (automation workflows)
• Prometheus (metrics collection)

First-run on this Mac

1. Open Rancher Desktop from Applications.
2. Complete first-run setup in the GUI.
3. In Rancher Desktop settings, ensure Docker CLI is enabled.
4. Open a new terminal and run:

   cd /Users/farm/blackfish/projects/farm-control
   ./start.sh
   

Default endpoints

• Grafana: http://localhost:3000
• Node-RED: http://localhost:1880
• MQTT broker: localhost:1883
• PostgreSQL: localhost:5432
• Prometheus: http://localhost:9090
• Mac host metrics exporter: http://localhost:9100/metrics

Mac performance metrics

This Mac is monitored via node_exporter (installed with Homebrew and started as a service). Prometheus scrapes it at host.docker.internal:9100, and Grafana uses Prometheus as default datasource. Grafana also auto-loads a dashboard: Mac Host Overview (folder: Farm Control).

Important

Edit .env and change default passwords before exposing this machine on a farm network.
