OpenClaw AI Gateway - Setup on NUC

Date: 2026-02-12 02:30 Context: Deployed OpenClaw (self-hosted AI assistant gateway) on the NUC via Docker Compose, connected WhatsApp channel.

What Was Done

  1. Cloned repo on NUC: git clone https://github.com/openclaw/openclaw.git ~/openclaw
  2. Built Docker image natively on NUC (x86/amd64, no cross-compile): docker build -t openclaw:local -f Dockerfile .
  3. Created config at ~/.openclaw/openclaw.json with Anthropic Claude model
  4. Generated gateway token: 3547c3f2b7b4a33eb077cf804bcca446057f81ba1578b2045dbb3aa4e04346ee
  5. Started gateway via docker compose up -d openclaw-gateway
  6. Ran doctor --fix to migrate config schema and create required directories
  7. Set up Tailscale Serve on port 8443 for HTTPS access (Control UI requires secure context)
  8. Approved device pairing for browser access
  9. Configured Anthropic OAuth token (generated via claude setup-token on Mac, valid 1 year)
  10. Enabled WhatsApp plugin and linked via QR code

Key Decisions

  • Built on NUC, not Mac — NUC is x86/amd64 so native build is faster than cross-compiling from ARM Mac
  • Not deployed via Coolify — OpenClaw uses its own docker-compose with specific volume mounts and CLI container; Coolify would add complexity without benefit
  • Tailscale Serve (not Funnel) — Only needs tailnet access, not public internet. Port 8443 (443 taken by Turbostarter)
  • API key via env var — Set ANTHROPIC_API_KEY in both ~/.openclaw/openclaw.json and ~/openclaw/.env for reliability
  • script command for QR capture — The CLI needs a TTY for QR display; script -qc '...' /dev/null fakes a PTY over non-interactive SSH

Issues Encountered & Solutions

Issue Cause Solution
Config "invalid" after creation Used legacy agent.model key Use agents.defaults.model.primary; run doctor --fix
"control ui requires HTTPS" Web Crypto API needs secure context Tailscale Serve on port 8443
"pairing required" New browser device not approved devices list + devices approve <requestId> via docker exec
"unauthorized: gateway token missing" UI didn't have token Use dashboard URL with #token=... hash
CLI docker compose run can't reach gateway CLI container gets different Docker IP Use docker exec into running gateway container instead
channels login fails "unsupported channel" Channel plugin not enabled plugins enable whatsapp first, then restart gateway
sudo tailscale serve fails via SSH No TTY for sudo password Must run from interactive SSH session on NUC
WhatsApp QR not visible No TTY in non-interactive SSH Use script -qc '...' /tmp/output.txt to capture with fake TTY

Files Modified

  • ~/openclaw/.env — Docker Compose env vars (token, API key, paths)
  • ~/openclaw/docker-compose.yml — Added ANTHROPIC_API_KEY env var to gateway service
  • ~/.openclaw/openclaw.json — Gateway config (model, auth, env)
  • /Users/agutierrez/Desktop/nuc/CLAUDE.md — Added full OpenClaw documentation section
