summary
A floating, IP68 submersible buoy running Raspberry Pi hardware with an 18 W solar panel, LiPo battery, multiple sensors and a 3G modem collects temperature, nutrient and flow data hourly from reefs 100 meters offshore. A k0s single-binary Kubernetes cluster boots in minutes on the Pi fleet, enforces resource limits, auto-restarts and reschedules pods, and uses NATS messaging for low-latency telemetry. Cosmotron control plane manages multi-site clusters; the second‑generation system is deployed and operating in Vietnam and Mauritius.
