+- **Automatic**: **seelf** will deploy and configure a [traefik](https://traefik.io/traefik/) proxy on the target. Services urls will be automatically generated based on the [target's url](#url) and [service file](/reference/providers/docker#exposing-services) when deploying. Exposed services will also join the proxy network.

 The scheme associated with this url (`http` or `https`) will determine if certificates should be generated or not.
