## Labels: overriding default behaviour

If you use a compose file, labels should be defined in the `deploy` part of your service.

This behavior is only enabled for docker-compose version 3+ ([Compose file reference](https://docs.docker.com/compose/compose-file/#labels-1)).

#### Using Docker Compose

If you are intending to use only Docker Compose commands (e.g. `docker-compose up --scale whoami=2 -d`), labels should be under your service, otherwise they will be ignored.

[1] `traefik.docker.network`:
|
||||
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.
|
||||
Or if your service references external network use it's name instead.
