I have created a website I wanted to deploy with Docker and Traeffik.
When I deploy the services manually, everything works like a charm.
First create a network
docker network create --driver overlay traefik-net
Next create the Traefik service
docker service create \
--name traefik \
--constraint=node.role==manager \
--publish 80:80 --publish 8080:8080 \
--mount type=bind,source=/var/run/docker.sock,target=/var/run/docker.sock \
--mount type=bind,source=$PWD/traefik.toml,target=/etc/traefik/traefik.toml \
--network traefik-net \
traefik \
--docker \
--docker.swarmMode \
--docker.domain=traefik \
--docker.watch \
--api
And lastly, create the website service
docker service create \
--name johanvergeer \
--label traefik.port=4000 \
--label traefik.frontend.rule='Host:johanvergeer.com' \
--network traefik-net \
registry.gitlab.com/johanvergeer/redgyro/site:latest
For configuration I have create a traefik.toml file
[entryPoints]
[entryPoints.http]
address = ":80"
[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "mydomain.com"
watch = true
exposedByDefault = true
usebindportip = true
swarmMode = true
But when I stop the services and try to start them with Docker stack, it won't work for some reason.
The docker-compose file
version: "3.6"
services:
site:
ports:
- 4000:4000
image: mywebsite:latest
labels:
- traefik.site.port=4000
- traefik.enable=true
- traefik.frontend.rule=Host:mydomain.com
networks:
- traefik-net
reverse-proxy:
image: traefik # The official Traefik docker image
ports:
- "80:80" # The HTTP port
- "8080:8080" # The Web UI (enabled by --api)
volumes:
- /var/run/docker.sock:/var/run/docker.sock # So that Traefik can listen to the Docker events
- $PWD/traefik.toml:/etc/traefik/traefik.toml
deploy:
labels:
traefik.logLevel: 'DEBUG'
placement:
constraints:
- node.role == manager
update_config:
parallelism: 1
delay: 10s
restart_policy:
condition: on-failure
networks:
- traefik-net
networks:
traefik-net:
name: traefik-net
In the log of the traefik service I can see that the traefik.site.port=4000 label is not used.
Next to that I also noticed the empty Docker configuration: level=debug msg="Configuration received from provider docker: {}"
level=info msg="Using TOML configuration file /etc/traefik/traefik.toml"

This already cost me all day by now, for a probably very simple setting I'm missing somewhere. Could someone help me out with this one?
When using traefik configured for swarm mode, you need to set the label on the service rather than the container. You do that by moving the labels inside of a deploy block in the compose file:
services:
site:
ports:
- 4000:4000
image: mywebsite:latest
deploy:
labels:
- traefik.site.port=4000
- traefik.enable=true
- traefik.frontend.rule=Host:mydomain.com
networks:
- traefik-net
