Adds services/wolf-pair.sh (gaming group, port 8090). Builds a tiny python:3.12-alpine container from server.py + Dockerfile (both baked into the script) that reads Wolf's docker logs for the current pairing secret and serves a PIN entry form. Runs with network_mode: host so localhost:47989 (Wolf's /pin/ API) is reachable; docker socket mounted read-only for log access. Replaces the ./manage.sh pin CLI workflow: visit the URL, type the PIN. Optional Caddy subdomain, UFW port 8090, README in ~/docker/wolf-pair/. Bumps version to 0.9.8.

GET / → if a fresh pairing secret is pending: serve a PIN form.
|
|
if none: serve a waiting page that auto-refreshes.
|
|
POST / → take the PIN from the form, attach the freshest secret read from
|
|
Wolf's logs, and proxy {pin, secret} to Wolf's /pin/ endpoint.
|
|
|
|
Wolf's pairing secrets are SINGLE-USE: Wolf erases a secret from its map the
|
|
instant any PIN is submitted for it (correct or not). Because the secret stays
|
|
in `docker logs` forever, we must never re-offer a secret we've already
|
|
submitted — otherwise the user resubmits a dead secret and Wolf returns
|
|
"key not found". We track submitted secrets and fall back to the waiting page
|
|
until Moonlight initiates a brand-new pairing (which mints a new secret).

|
|
|
|
Browser-based Moonlight pairing helper for Wolf.
|
|
|
|
Visit `http://<server-ip>:8090` when Moonlight shows a pairing PIN — the page
|
|
detects the pending request automatically (auto-refreshes every 3 s while
|
|
waiting) and lets you type the PIN without running any CLI commands.
|
|
|
|
## How it works
|
|
|
|
1. In Moonlight, add this server → a 4-digit PIN appears.
|
|
2. Open `http://<server-ip>:8090` in any browser.
|
|
3. The page shows a PIN form — type the PIN and press **Pair**.
|
|
|
|
The server reads Wolf's docker logs for the current pairing secret, submits
|
|
`{pin, secret}` to Wolf's `/pin/` API, and marks the secret as used so a
|
|
stale browser tab can never re-submit a dead secret.
|
|
|
|
## Manage
|
|
|
|
```bash
|
|
cd ~/docker/wolf-pair
|
|
docker compose up -d # start
|
|
docker compose down # stop
|
|
docker compose up -d --build # rebuild after source changes
|
|
docker compose logs -f # follow logs
|
|
```
|
|
|
|
## Notes
|
|
|
|
- Requires the Wolf container (`wolf`) to be running.
|
|
- Moonlight's actual video/audio stream is direct UDP/TCP to the server IP
|
|
and cannot be proxied — only the pairing page goes through wolf-pair.
|
|
- If you set up a Caddy subdomain (e.g. `wolf-pair.yourdomain.com`), that
|
|
subdomain is for the PIN form only.
