# Operations

## Web UI

Start the web UI daemon:

```bash
python3 -m gibil.scripts.web_daemon
```

The daemon listens on:

```text
http://0.0.0.0:8080
```

By default the server binds to all network interfaces so it can be reached from another machine. Override the bind address or port if needed:

```bash
export ASTRAPE_WEB_HOST='0.0.0.0'
export ASTRAPE_WEB_PORT='8080'
```

The host process reloads `webui.py` and display modules on each request. The browser polls `/api/ui-version` and refreshes when those files change.

## Systemd Services

Install service units:

```bash
sudo cp deploy/systemd/astrape-web.service /etc/systemd/system/
sudo cp deploy/systemd/astrape-db.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now astrape-web.service astrape-db.service
```

Check status:

```bash
systemctl status astrape-web.service
systemctl status astrape-db.service
journalctl -u astrape-web.service -f
journalctl -u astrape-db.service -f
```

Both services run as the IPA-managed `gibil` user from `/mnt/astrape`.

## Database Daemon

Install runtime dependencies:

```bash
python3 -m pip install -r requirements.txt
```

Create a local env file:

```bash
cp env/astrape.env.example env/astrape.env
nano env/astrape.env
```

Required values:

```text
ASTRAPE_DATABASE_URL=postgresql://USER:PASSWORD@HOST:PORT/DBNAME
ASTRAPE_LATITUDE=59.0000
ASTRAPE_LONGITUDE=18.0000
```

Optional values:

```text
ASTRAPE_WEATHER_FORECAST_HOURS=48
ASTRAPE_WEATHER_POLL_SECONDS=3600
ASTRAPE_WEATHER_TRUTH_LOOKBACK_DAYS=14
ASTRAPE_WEATHER_TRUTH_END_DELAY_DAYS=5
```

The daemons load `env/*.env` automatically. Existing process environment variables win over file values.

For temporary frontend tuning, enable display-only sample weather data:

```text
ASTRAPE_WEB_SAMPLE_DATA=1
```

This does not write artificial data to TimescaleDB. It only changes the web UI weather API response.

Start the database ingest daemon:

```bash
python3 -m gibil.scripts.db_daemon
```

Current behavior:
- initializes TimescaleDB weather tables
- fetches real Open-Meteo hourly forecasts
- normalizes them through `WeatherBuilder`
- stores rows in `weather_forecast_points`
- fetches Open-Meteo archive data for resolved truth
- stores rows in `weather_resolved_truth`
- repeats every `ASTRAPE_WEATHER_POLL_SECONDS`

No internal weather predictions are generated here. This daemon only stores external forecast and resolved-truth data for later modules.
