|

- `traefik.docker.network`: Set the docker network to use for connections to this container. If a container is linked to several networks, be sure to set the proper network name (you can check with docker inspect <container_id>) otherwise it will randomly pick one (depending on how docker is returning them). For instance when deploying docker `stack` from compose files, the compose defined networks will be prefixed with the `stack` name.
