Question

我用以下撰写文件创建了一个Docker Swarm：

version: '3.5'
services:
  traefik:
    image: traefik:v1.7.12
    deploy:
      replicas: 1
      placement:
        constraints: [ node.role == manager ]    
    networks:
      - frontend
    ports: 
      - "80:80"
      - "443:443"
      - "8081:8080"
    volumes:
      - ./traefik.toml:/etc/traefik/traefik.toml
      - ./access.log:/var/log/access.log
      - ./acme.json:/etc/traefik/acme.json
      - ./traefik.log:/var/log/traefik.log
      - /var/run/docker.sock:/var/run/docker.sock
  test:
    image: emilevauge/whoami
    deploy:
      labels:
        - "traefik.frontend.rule=Host:myserver;Path:/test"
        - "traefik.port=80"
    networks:
      - frontend

networks:
  frontend:
    name: "frontend"
    driver: overlay

这是我的traefik.toml文件：

defaultEntryPoints = [ "http" ]

[traefikLog]
    filePath = "/var/log/traefik.log"

[accessLog]
    filePath = "/var/log/access.log"
    [accessLog.fields]
        defaultMode = "keep"
        [accessLog.fields.names]
            "FrontendName" = "keep"
            "BackendName" = "keep"

[entryPoints]
    [entryPoints.dashboard]
    address = ":8080"
    [entryPoints.http]
    address = ":80"

[api]
    entrypoint = "dashboard"
    debug = true
    dashboard = true
    [api.statistics]

[ping]
    entrypoint = "http"

[docker]
    watch = true
    swarmMode = true
    endpoint = "unix:///var/run/docker.sock"
    network = "frontend"

我已经在Digital Ocean的一个小滴上部署了这种配置的集群，并发现它可以正常工作。但是，我需要在工作场所中部署到Ubuntu虚拟服务器，这就是我遇到的问题。服务器位于外部负载均衡器后面。当我将此群部署到我的工作服务器时，我无法连接到whoami（端口80）服务器或traefik仪表板（端口8081）。我的浏览器显示ERR_CONNECTION_RESET和“无法访问此站点”。

我已在我公司的技术支持下验证端口是否打开。另外，如果我在工作服务器上启动以下traefik-less的配置，则whoami服务将按预期工作：

version: '3.5'
services:
  test:
    image: emilevauge/whoami
    networks:
      - frontend
    ports:
      - "80:80" # works with 8081:80 too
networks:
  frontend:
    name: "frontend"
    driver: overlay

最后，我检查了access.log文件，但找不到我的网络浏览器的任何访问记录。唯一的访问权限似乎是每秒更新一次：

10.255.0.2 - - [06/Aug/2019:13:19:23 +0000] "GET / HTTP/1.1" 404 19 "-" "a10hm/1.0" 245 "backend not found" "/" 0ms
10.255.0.2 - - [06/Aug/2019:13:19:24 +0000] "GET / HTTP/1.1" 404 19 "-" "a10hm/1.0" 246 "backend not found" "/" 0ms
10.255.0.2 - - [06/Aug/2019:13:19:28 +0000] "GET / HTTP/1.1" 404 19 "-" "a10hm/1.0" 247 "backend not found" "/" 0ms
10.255.0.2 - - [06/Aug/2019:13:19:29 +0000] "GET / HTTP/1.1" 404 19 "-" "a10hm/1.0" 248 "backend not found" "/" 0ms
10.255.0.2 - - [06/Aug/2019:13:19:34 +0000] "GET / HTTP/1.1" 404 19 "-" "a10hm/1.0" 249 "backend not found" "/" 0ms
10.255.0.2 - - [06/Aug/2019:13:19:34 +0000] "GET / HTTP/1.1" 404 19 "-" "a10hm/1.0" 250 "backend not found" "/" 0ms
10.255.0.2 - - [06/Aug/2019:13:19:39 +0000] "GET / HTTP/1.1" 404 19 "-" "a10hm/1.0" 251 "backend not found" "/" 0ms
10.255.0.2 - - [06/Aug/2019:13:19:39 +0000] "GET / HTTP/1.1" 404 19 "-" "a10hm/1.0" 252 "backend not found" "/" 0ms

我应该检查些什么以找出为什么我的http请求似乎没有达到traefik？是我公司的外部负载平衡器引起问题还是traefik出了问题？

为什么Traefik无法在外部负载均衡器后面工作？
