 Or use a `.env` file with docker-compose:

+**Note**: The WS4KP weather service runs internally on port 8080 inside the container and is always accessible to the streaming app. The `WS4KP_EXTERNAL_PORT` controls whether it's exposed externally. If you don't need direct access to the WS4KP interface, you can comment out the WS4KP port mapping in `docker-compose.yml` to keep it internal-only.

 ### Persistent Geocoding Cache
 
 Geocoding results are cached in the `./cache` directory. When using docker-compose, this directory is automatically mounted to persist between container restarts. If using Docker directly, mount the cache volume to persist data:
