Labels: overriding default behavior

Using Docker with Swarm Mode

If you use a compose file with the Swarm mode, labels should be defined in the deploy part of your service. This behavior is only enabled for docker-compose version 3+ (Compose file reference).

version: "3"
services:
  whoami:
    deploy:
      labels:
        traefik.docker.network: traefik

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.

version: "3"
services:
  whoami:
    labels:
      traefik.docker.network: traefik

[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.

[2] traefik.frontend.auth.basic.users=EXPR :
To create user:password pair, it's possible to use this command:
echo $(htpasswd -nb user password) | sed -e s/\\$/\\$\\$/g.
The result will be user:$$apr1$$9Cv/OMGj$$ZomWQzuQbL.3TRCS81A1g/, note additional symbol $ makes escaping.

!!! note If a label is defined both as a container label and a segment label (for example traefik.<segment_name>.port=PORT and traefik.port=PORT ), the segment label is used to defined the <segment_name> property (port in the example).

It's possible to mix `container labels` and `segment labels`, in this case `container labels` are used as default value for missing `segment labels` but no frontends are going to be created with the `container labels`.

More details in this [example](/user-guide/docker-and-lets-encrypt/#labels).

!!! warning When running inside a container, Træfik will need network access through:
