docker - Traefik 2.0 "port is missing"用于内部仪表板

Question

我正在尝试在 docker swarm 模式下使用 traefik 2.0 (!)。这是我的堆栈:

version: '3.7'
services:
  traefik:
    image: traefik:latest
    ports:
      - 80:80
      - 443:443
    deploy:
      replicas: 1
      placement:
        constraints:
          - node.role == manager
        preferences:
          - spread: node.id
      labels:
        - traefik.enable=true
        - traefik.http.routers.traefikRouter.rule=Host(`127.0.0.11`)
        - traefik.http.routers.traefikRouter.service=api@internal
        - traefik.http.routers.traefikRouter.entrypoints=http
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    command: >
      --providers.docker
      --providers.docker.exposedbydefault=false
      --providers.docker.swarmmode=true
      --entryPoints.http.address=":80"
      --entryPoints.https.address=":443"
      --accesslog
      --log.level=DEBUG
      --api=true
      --api.dashboard=true
    networks:
      - traefik-public

  whoami:
    image: containous/whoami
    deploy:
      replicas: 2
      labels:
        - traefik.enable=true
        - traefik.http.services.whoami.loadbalancer.server.port=80
        - traefik.http.routers.whoami.rule=Host(`127.0.0.12`)
        - traefik.http.routers.whoami.service=whoami
        - traefik.http.routers.whoami.entrypoints=http
    networks:
      - traefik-public

# Run on Host: docker network create --driver=overlay traefik-public
networks:
  traefik-public:
    external: true

访问 http://127.0.0.12/有效，我看到 whoami 页面。
访问 http://127.0.0.11/或 http://127.0.0.11/dashboard/应该显示 traefiks 内部仪表板，如果我读了 the docs对。但是我得到了 traefiks 404。
docker service log显示一个错误:

level=error msg="port is missing" container=traefik-traefik-z8kz9w91yw7pm6tp5os5vxrnv providerName=docker

有什么问题？我怀疑它缺少服务的端口 api@internal ...但那是它的内部服务 - 我不能配置？!

有任何想法吗？谢谢

好的，只需在标签中添加一个虚拟服务端口即可

      labels:
        - traefik.enable=true
        - traefik.http.services.justAdummyService.loadbalancer.server.port=1337
        - traefik.http.routers.traefikRouter.rule=Host(`127.0.0.11`)
        - traefik.http.routers.traefikRouter.service=api@internal
        - traefik.http.routers.traefikRouter.entrypoints=http

我现在在 traefik 上挣扎了超过 24 小时......这不可能是解决方案，对吧？
猜猜我必须将此报告为错误。有人可以确认这不是它应该如何工作吗？
