"Prometheus Jetson: Services & Cloudflare Infrastructure"

2026-02-17

Prometheus Jetson — Services & Cloudflare Infrastructure

Host: NVIDIA Jetson Orin Nano (8GB RAM, 916GB NVMe SSD, CUDA 12.6, JetPack 6.2) LAN IP: 192.168.0.18 | SSH: ssh prometheus Domain: *.digitalsurfacelabs.com (all subdomains via Cloudflare Tunnel)

Cloudflare Tunnel

A single Cloudflare Tunnel (buddy-tunnel, UUID 565455e8-...) connects the Jetson to the public internet. No port forwarding or static IP needed — cloudflared makes an outbound QUIC connection to Cloudflare's edge, which then routes incoming requests back through the tunnel to local ports.

Config: /etc/cloudflared/config.yml Credentials: /home/prometheus/.cloudflared/565455e8-2d47-4ae4-b735-9845454006ae.json Systemd: cloudflared.service (enabled, auto-restart on failure) Auto-update: cloudflared-update.service restarts cloudflared if a new version is available
