# yaris-obd remote server

A small Flask + Postgres API that receives trip/GPS log batches and dashcam
video files uploaded by the Pi (see the repo root [readme.md](../readme.md)
and [PLAN.md](../PLAN.md) for the overall project). Designed to run as a
docker-compose stack on an unraid server (or any Docker host).

## What it does

- `GET /health` — unauthenticated liveness check.
- `POST /api/v1/tracking/batch` — bulk-insert a batch of GPS/trip points.
- `POST /api/v1/dashcam/upload` — upload one dashcam video file (multipart,
  content-addressed by sha256 so retries/duplicates are safe).

Both upload endpoints require two headers: `X-Device-Name` and `X-Api-Key`
(see [Registering a device](#registering-a-device-and-getting-an-api-key)
below). Postgres is **not** published to the LAN — only the `api` container
talks to it, over the internal compose network.

## Deploying on unraid

1. Get the code onto the unraid box (same repo as the Pi, just the
   `server/` sub-folder matters here):
   ```bash
   ssh root@<unraid-ip>
   mkdir -p /mnt/user/app/git && cd /mnt/user/app/git
   git clone git@github.com:quoije/yaris-obd.git
   cd yaris-obd/server
   ```
2. Copy the env template and fill in a real Postgres password:
   ```bash
   cp .env.example .env
   nano .env   # set POSTGRES_PASSWORD, and DATA_DIR if you want data on the array
   ```
   Recommended `DATA_DIR` for unraid: `/mnt/user/appdata/yaris-obd-server`
   (keeps Postgres data + dashcam files on the array, backed up like your
   other appdata).
3. Build and start the stack:
   ```bash
   docker compose up -d --build
   ```
   This is also importable into unraid's **Compose Manager** plugin if you'd
   rather manage start/stop/updates from the Unraid UI.
4. Confirm it's healthy:
   ```bash
   docker compose ps
   curl http://localhost:8098/health
   ```

## Registering a device and getting an API key

Run this once per device (e.g. once for the Pi) after the stack is up:

```bash
docker compose exec api python3 scripts/create_device.py yaris-2013
```

This prints a one-time API key — copy the `YARIS_UPLOAD_DEVICE_NAME` /
`YARIS_UPLOAD_API_KEY` values into the Pi's upload-client config. Only the
key's sha256 hash is stored server-side; the raw key is never shown again
(re-run the script with the same device name to rotate/replace the key).

## Exposing it outside the LAN

Two options, either works with this API unchanged:

- **Cloudflare Tunnel** (already running on this unraid box): add a public
  hostname rule in the Cloudflare dashboard pointing at
  `http://<unraid-lan-ip>:8098` (or `http://api:8098` if you point the
  tunnel at the `api` container directly on the compose network). Good for
  small tracking-data batches; large dashcam uploads may hit the tunnel's
  per-request size limit.
- **Router port-forward** (fallback if needed): forward an external port to
  `<unraid-lan-ip>:8098` and let your router/firewall (e.g. Unifi) handle
  the security side. No changes needed here either way.

For large dashcam uploads from home, consider adding a local DNS
override/rewrite (e.g. in AdGuard Home, same trick used for `yaris.local` on
the Pi) so the hostname resolves directly to the unraid LAN IP while on the
home network, bypassing the tunnel entirely for big transfers.

## Toggling dashcam uploads off

The Pi's web UI has a setting to pause dashcam file uploads while keeping
GPS/trip log uploads running — no server-side change needed, the Pi simply
stops calling `/api/v1/dashcam/upload` while the toggle is off.

## Local development / testing without unraid

```bash
cd server
cp .env.example .env   # edit POSTGRES_PASSWORD
docker compose up --build
curl http://localhost:8098/health
```
