A Swiss Cloud-Native Farm 🐄
summary
A working on‑prem farm stack: a 4‑node bare‑metal cluster (~$350/node, 16GB each) runs Kubernetes on Talos Linux, managed with OpenTofu and GitOps (FluxCD); monitoring uses VictoriaMetrics + Grafana (VMagent → VMinsert → VMstorage → VMselect) storing decade‑long milking history. A custom Go Prometheus exporter reads MS SQL milk data (with backfill) and a gRPC bridge exposes an EtherSbus controller for the biogas plant; Home Assistant controls Shelly relays for fences and a cheap level sensor alerts the milk vending machine. IPv6 neighbor‑discovery provides a nearly zero‑cost redundant ingress.
