+# 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
