By default, a container uses the default bridge network, requiring each internal port to be mapped to an external port (using the `-p` or `--publish` argument). If another network type is used, changing this port may prevent conflicts with other services/containers. **NOTE**: A value of `-1` disables VNC access to the application's GUI. | `5900` |
