Traefik 2 only publishes port 80 and ignores 443 and dashboard port on docker swarm

Traefik Traefik v2

Hi,

I have been banging my head off trying to get SSL working with traefik 2 on docker swarm. This is the docker stack file I'm using:

version: '3.7'

services:
  traefik:
    hostname: traefik
    image: traefik:v2.2.0
      - --entrypoints.web.address=:80
      - --entrypoints.websecure.address=:443
      - --providers.docker
      - --providers.docker.swarmmode=true
      - --providers.docker.domain=example.com
      - --providers.docker.watch
      - --providers.docker.network=traefik_proxy
      - --api.dashboard=true
      - --providers.docker.endpoint=/var/run/docker.sock
      - --log.filePath=/dev/stdout
      - --log.level=DEBUG
      - --serversTransport.insecureSkipVerify=true
    deploy:
        replicas: 1
      labels:
        # Dashboard
        - "traefik.http.routers.traefik.rule=Host(`traefik.localhost`)"
        - "traefik.http.routers.traefik.service=api@internal"
        - "traefik.http.routers.traefik.entrypoints=websecure"
        - "traefik.http.routers.traefik.tls=true"

        # Redirect a https global
        - "traefik.http.routers.http-catchall.rule=hostregexp(`{host:.+}`)"
        - "traefik.http.routers.http-catchall.entrypoints=web"
        - "traefik.http.routers.http-catchall.middlewares=redirect-to-https"

        # Redirect del middleware
        - "traefik.http.middlewares.redirect-to-https.redirectscheme.scheme=https"
      placement:
        constraints:
          - node.role == manager
      update_config:
        parallelism: 2
        delay: 10s
      restart_policy:
        condition: on-failure
    networks:
      - traefik_proxy
      - zbx_net
    ports:
      - "80:80"
      - "443:443"
      - "8000:8000"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro

networks:
  traefik_proxy:
    external:
      name: traefik_proxy
  zbx_net:
    external:
      name: zbx_net
  # default:
  #   driver: bridge

The container should not even start as port 8000 is aldeady in use by another service, nonetheless traefik starts without complaining. Even the debug flag seems to not work either as I don't get any kind of output on stdout. Thei ssue is only with traefik 2 in swarm mode, the following compose file for traefik 2 works fine:

version: '3.7'
services:
  traefik:
    image: "traefik:v2.2.0"
    command:
      - --entrypoints.web.address=:80
      - --entrypoints.websecure.address=:443
      - --providers.docker
      - --api.dashboard=true
      # Para depurar:
      # - --log.filePath=/dev/stdout
      # - --log.level=DEBUG
      - --serversTransport.insecureSkipVerify=true
    ports:
      - "80:80"
      - "443:443"
      - "8001:8000"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
    labels:
      # Dashboard
      - "traefik.http.routers.traefik.rule=Host(`traefik.localhost`)"
      - "traefik.http.routers.traefik.service=api@internal"
      - "traefik.http.routers.traefik.entrypoints=websecure"
      - "traefik.http.routers.traefik.tls=true"

      # Redirect a https global
      - "traefik.http.routers.http-catchall.rule=hostregexp(`{host:.+}`)"
      - "traefik.http.routers.http-catchall.entrypoints=web"
      - "traefik.http.routers.http-catchall.middlewares=redirect-to-https"

      # Redirect del middleware

docker inspect output:

        "PortBindings": {
                "443/tcp": [
                    {
                        "HostIp": "",
                        "HostPort": "443"
                    }
                ],
                "80/tcp": [
                    {
                        "HostIp": "",
                        "HostPort": "80"
                    }
                ],
                "8000/tcp": [
                    {
                        "HostIp": "",
                        "HostPort": "8001"
                    }
                ]
            }

docker ps output:


CONTAINER ID        IMAGE                        COMMAND                  CREATED             STATUS              PORTS               NAMES

On the other hand, this traefik 1.7 stack file works fine on docker swarm:

version: '3.7'

services:
  traefik:
    hostname: traefik
    image: traefik:1.7
    container_name: traefik
    command:
      - --web
      - --entrypoints=Name:http Address::80 Redirect.EntryPoint:https
      - --entryPoints=Name:https Address::443 TLS
      - --defaultentrypoints=http,https
      - --docker
      - --docker.swarmmode
      - --docker.domain=corona.co
      - --docker.watch
      - --docker.network=traefik_proxy
    deploy:
#      mode: global
      replicas: 1
      placement:
        constraints:
          - node.role == manager
      update_config:
        parallelism: 2
        delay: 10s
      restart_policy:
        condition: on-failure
    networks:
      - traefik_proxy
      - zbx_net
    ports:
      - "80:80"
      - "443:443"
      - "8001:8000"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro

What I'm doing wrong ?

Thanks in advance

Hello,

The labels section must be put in the deploy section same as the v1:

deploy:
  labels:
    # ...

Hi Idez,

I just checked and that's a copy paste error, the labels are under deploy as they should be. I will update my post.
