@ -844,7 +844,7 @@ Labels can be used on containers to override default behaviour:
- `traefik.frontend.passHostHeader=true`: forward client `Host` header to the backend.
- `traefik.frontend.priority=10`: override default frontend priority
- `traefik.frontend.entryPoints=http,https`: assign this frontend to entry points `http` and `https`. Overrides `defaultEntryPoints`.
- `traefik.docker.network`: Set the docker network to use for connections to this container
- `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.
If several ports need to be exposed from a container, the services labels can be used
- `traefik.<service-name>.port=443`: create a service binding with frontend/backend using this port. Overrides `traefik.port`.
