Setting up traefik with docker swarm [field not found, node: port:8080]

Good morning.

I'm trying to set up traefik with docker swarm, I have been following this guide https://dockerswarm.rocks/ but I'm stuck.

This is my current setup:

traefik.yml

api:
  dashboard: true

entryPoints:
  web:
    address: ":80"
    http:
      redirections:
        entryPoint:
          to: websecure
          scheme: https
  websecure:
    address: ":443"
          
providers:
  docker:
    endpoint: "unix:///var/run/docker.sock"
    exposedByDefault: false
    swarmMode: true
  file:
    filename: /traefik-dynamic.yml
    watch: true
      
certificatesResolvers:
  lets-encrypt:
    acme:
      email: some_email
      storage: acme.json
      httpChallenge:
        entryPoint: web

log:
  filePath: "/log.log"
  level: DEBUG

treaefik-dynamic.yml

http:
  middlewares:
    traefik-auth:
      basicAuth:
        users:
          - "user:hash"

docker-compose.yml for traefik

version: '3'

services:
  traefik:
    image: traefik:latest
    container_name: traefik
    restart: unless-stopped
    security_opt:
      - no-new-privileges:true
    deploy:
      placement:
        constraints:
            # Make the traefik service run only on the node with this label
            # as the node with it has the volume for the certificates
            #- node.labels.traefik-public.traefik-public-certificates == true
            - node.role == manager
      labels:
        - "traefik.enable=true"
        - "traefik.http.routers.traefik.rule=Host(`traefik2.domain.net`)"
        - "traefik.http.routers.traefik.entrypoints=websecure"
        #- "traefik.http.routers.traefik.middlewares=traefik-auth@file"
        - "traefik.http.services.traefik.loadbalancer.server.port:8080"
        - "traefik.http.routers.traefik.tls=true"
        - "traefik.http.routers.traefik.tls.certresolver=lets-encrypt"
        - "traefik.http.routers.traefik.service=api@internal"
    command:
      - --entrypoints.redis.address=:6379 # Redis endpoint.
    ports:
      - 80:80
      - 443:443
      - 8080:8080
    volumes: 
      - /etc/localtime:/etc/localtime:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./data/traefik.yml:/traefik.yml:ro
      - ./data/traefik-dynamic.yml:/traefik-dynamic.yml:ro
      - ./data/acme.json:/acme.json
      - ./data/log.log:/log.log
      - ./certs:/certs
    networks:
      - traefik-public

networks:
  traefik-public:
    external: true

When I go to the dashboard I get 404 error. But the certificate is valid. Here's what I'm continuously seeing on the log:

time="2023-05-05T07:25:11Z" level=debug msg="Serving default certificate for request: """
time="2023-05-05T07:25:12Z" level=error msg="field not found, node: port:8080" providerName=docker container=traefik-traefik-96up1dje2kilr0vn5f9mfxw1a
time="2023-05-05T07:25:12Z" level=debug msg="Configuration received: {"http":{},"tcp":{},"udp":{}}" providerName=docker
time="2023-05-05T07:25:12Z" level=debug msg="Skipping unchanged configuration." providerName=docker
time="2023-05-05T07:25:27Z" level=error msg="field not found, node: port:8080" providerName=docker container=traefik-traefik-96up1dje2kilr0vn5f9mfxw1a
time="2023-05-05T07:25:27Z" level=debug msg="Configuration received: {"http":{},"tcp":{},"udp":{}}" providerName=docker
time="2023-05-05T07:25:27Z" level=debug msg="Skipping unchanged configuration." providerName=docker

But I don't see what's wrong with the port definition. Precisesly as I understand it specifing the port is a must in docker swarm.

Hello,

There is a typo:

it must be:

- "traefik.http.services.traefik.loadbalancer.server.port=:8080"

Sometimes I wonder how I have still not lost my head.

Thank you :slight_smile:
