我在 docker swarm 环境中部署 portainer 和 traefik。我可以使用 domain 访问 traefik 仪表板traefik.example.com。我还想代理到 portainer 容器，但是当我点击时portainer.example.com出现 404 错误。traefik 中的日志没有显示任何关于点击该网址的信息

但是当我使用端口号 9000 公开 portainer 并点击时，example.com:9000我可以得到它的 UI。所以这意味着也许我的规则不起作用或什么的。这是我在搬运工服务中使用的标签

      labels:
        - 'traefik.enable=true'
        - 'traefik.http.routers.portainer.entrypoints=http'
        - 'traefik.http.routers.portainer.rule=Host(`portainer.${DOMAIN}`)'
        # - 'traefik.http.routers.portainer_.entryPoints=websecure'
        - 'traefik.http.routers.portainer.service=portainer'
        - 'traefik.http.services.portainer.loadbalancer.server.port=9000'

和 traefik 服务的标签

 labels:
        - traefik.enable=true
        - traefik.port=8080
        - traefik.frontend.rule=Host(`traefik.${DOMAIN}`) #traefik.${DOMAIN}

我把它们放在同一个网络上， traefik service

    networks:
      - proxy
      - traefik-consul
      - traefik-docker

portainer service

    networks:
      - proxy
      - portainer

PS：Traefik 使用的是这张图片image: traefik:v1.7.16

我真的不明白。。
