Traefik v2 Docker Swarm - Not Finding Routers in Labels

[jake]

Hey,

I am attempting to route Wordpress traffic through a load balanced Traefik.

I have a 4 node swarm, 1 manager and 3 workers. The manager has a NFS shared volume which is mounted in the same spot on all 3 workers.

Here is the relevant docker compose (kept it super simple for my test run):

version: '3.9'

services:
  wordpress:
    depends_on:
      - db
      - traefik
    image: wordpress:latest
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_USER:
      WORDPRESS_DB_PASSWORD:
      WORDPRESS_DB_NAME: wordpress
    volumes:
      - /mnt/nfsshare/wordpress:/var/www/html
    deploy:
      replicas: 1
      placement:
        constraints: [node.role != manager]
      labels:
        - traefik.enable=true
        - traefik.http.routers.tattooedbrogrammer.rule=Host(`mywebsite.com`)
        - traefik.http.routers.tattooedbrogrammer.entrypoints=websecure
        - traefik.http.routers.tattooedbrogrammer.tls=true
        - traefik.http.routers.tattooedbrogrammer.tls.certresolver=myresolver
        - traefik.http.services.tattooedbrogrammer-svc.loadbalancer.server.port=80

  db:
    image: mariadb:latest
    environment:
      MYSQL_DATABASE: wordpress
      MYSQL_USER:
      MYSQL_ROOT_PASSWORD:
      MYSQL_PASSWORD:
    volumes:
      - db_data:/var/lib/mysql
    deploy:
      replicas: 1
      placement:
        constraints: [node.role == manager]

  traefik:
    image: traefik:latest
    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    volumes:
      - "/mnt/nfsshare/traefik/traefik.yml:/etc/traefik/traefik.yml"
      - "/mnt/nfsshare/letsencrypt:/letsencrypt"
      - "/var/run/docker.sock:/var/run/docker.sock"
      
volumes:
  db_data: {}

and in /mnt/nfsshare/traefik/traefik.yml I have the following config:

## traefik.yml

# Docker configuration backend
providers:
  docker:
    watch: true
    endpoint: "unix:///var/run/docker.sock"
    exposedByDefault: false
    swarmMode: true
    # network: traefik-public"
    #swarmModeRefreshSeconds: 5
    logLevel: DEBUG

## Static configuration
entryPoints:
  http:
    address: ":80"
    web:
      redirections:
        entryPoint:
          to: websecure
          scheme: https
  websecure:
    address: ":443"
    tls: {}

certificatesResolvers:
  myresolver:
    acme:
      email: admin@example.com
      storage: /letsencrypt/acme.json
      entryPoint: "https"
      tlsChallenge: {}

# API and dashboard configuration
api:
  insecure: true

Once deployed to the cluster, I get 1/1 replicated traefik and 1/1 replicated Wordpress service.

However the wordpress instance is not accessible via the web, and when I visit the dashboard on 8080, the router for tattooedbrogrammer does not exist.

I can confirm the yaml file on the worker node is correct through the nfs4 share:

What have I done wrong?

So after reading the entire docs, you can't use both Labels and Yaml to configure traefik. You have to chose one or the other. I switched my entire config into docker compose and it works now.
