|---|---|---|
| `icon` | `./docker-widget/icons/docker.svg` | Path to the icon |
| `number_of_containers` | `-1` | Number of last created containers to show |
| `executable_name` | `docker` | Name of the executable to use, defaults to `docker` |
| `max_widget_width` | 270 | Maximum width of the widget before the text breaks |
The `executable_name` allows you to use `Podman` instead of docker. This works since `Podman` is compatible to `docker` in the sense that the syntax and command outputs are identical.
