I have a Swarm cluster with a Manager and a Worker node. All the containers running on the manager are accessible through Traefik and working fine. I just deployed a new Worker node and joined my swarm on the node. Now I start scaling some services and realized they were timing out on the worker node.
So I setup a simple example using the whoami container, and cannot figure out why I cannot access it. Here are my configs (all deployed on the MANAGER node):
version: '3.6'
networks:
traefik-net:
driver: overlay
attachable: true
external: true
services:
whoami:
image: jwilder/whoami
networks:
- traefik-net
deploy:
labels:
- "traefik.port=8000"
- "traefik.frontend.rule=Host:whoami.myhost.com"
- "traefik.docker.network=traefik-net"
replicas: 2
placement:
constraints: [node.role != manager]
My traefik:
version: '3.6'
networks:
traefik-net:
driver: overlay
attachable: true
external: true
services:
reverse-proxy:
image: traefik # The official Traefik docker image
command: --docker --docker.swarmmode --docker.domain=myhost.com --docker.watch --api
ports:
- "80:80" # The HTTP port
# - "8080:8080" # The Web UI (enabled by --api)
- "443:443"
networks:
- traefik-net
volumes:
- /var/run/docker.sock:/var/run/docker.sock # So that Traefik can listen
- /home/ubuntu/docker-configs/traefik/traefik.toml:/traefik.toml
- /home/ubuntu/docker-configs/traefik/acme.json:/acme.json
deploy:
labels:
traefik.port: 8080
traefik.frontend.rule: "Host:traefik.myhost.com"
traefik.docker.network: traefik-net
replicas: 1
placement:
constraints: [node.role == manager]
My worker docker ps output:

I tried opening firewall ports, disabling it completely, nothing seems to work. Any help is appreciated
