未找到 Traefik Web UI 服务器

Question

我目前正在尝试在我的 RPi3 上的 docker 容器中设置 Traefik。截至目前，来自 Traefik 容器的日志显示验证成功并且服务器以证书响应：

pi@raspberrypi:~/docker $ sudo docker-compose logs -tf --tail="50" traefik

这是我的 docker-compose.yml 文件的副本：

      - traefik_proxy
    ports:

      - "443:443"
#      - "XXXX:8080"
    environment:

      - CLOUDFLARE_API_KEY=<my_cloudflare_api_key>
    labels:

#      - "traefik.frontend.rule=Host:${DOMAINNAME}; PathPrefixStrip: /traefik"
      - "traefik.port=8080"
      - "traefik.docker.network=traefik_proxy"
    volumes:

  traefik_proxy:
    external:
      name: traefik_proxy
  default:
    driver: bridge

这是我的 traefik.toml 文件：

#debug = true

logLevel = "ERROR" #DEBUG, INFO, WARN, ERROR, FATAL, PANIC
InsecureSkipVerify = true
defaultEntryPoints = ["https", "http"]

# WEB interface of Traefik - it will show web page with overview of frontend and backend configurations

  usersFile = "/shared/.htpasswd"

[acme.dnsChallenge]
  provider = "cloudflare"
  delayBeforeCheck = 0
[[acme.domains]]
   main = "aomosk.com"
[[acme.domains]]
   main = "*.aomosk.com"

# Connection to docker host system (docker.sock)
[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "aomosk.com"
watch = true
# This will hide all docker containers that don't have explicitly
# set label to "enable"
exposedbydefault = false
~                        

我已将我的 DNS 迁移到 Cloudflare，以便更好地使用 Traefik，并且我的外部 IP 有一条 A 记录，设置为我的域名，但是当我尝试时仍然出现找不到服务器页面并通过子域访问 web ui（当我使用任何其他方法时找不到 404 页面）。是否有一些我遗漏的东西导致 web ui 无法工作？

Answer 1

我有一个非常相似的设置和问题。我通过注释掉我的 traefik.toml 文件中的日志记录设置来解决它。

logLevel = "DEBUG"
[traefikLog]
  filePath = "/logs/traefik.log"
[accessLog]
  filePath = "/logs/access.log"

如果我把这些留在里面，我会得到 404 错误，如果我把它们注释掉，它会起作用。不知道是不是bug？

#logLevel = "DEBUG"
#[traefikLog]
#  filePath = "/logs/traefik.log"
#[accessLog]
#  filePath = "/logs/access.log"

Answer 2

我的问题有点不同。我在我的 AWS 服务器上设置了 traefik，起初，它在为 HTTP 配置时工作。但是当我为 HTTPS 配置它时它停止工作。我收到与此类似的“404 backend not found”错误

reverse-proxy_1  | 202.164.37.34 - - [10/Aug/2018:10:39:17 +0000] "GET /api/providers HTTP/1.1" 302 5 "http://<traefik-subdomain>.<hostname>/dashboard/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.84 Safari/537.36" 1091 "entrypoint redirect for frontend-Host-########-0" "/api/providers" 0ms

我采用了与 paul-taylor 在答案中给出的相同方法，通过注释掉日志记录并且它起作用了。这很不幸，因为日志记录本来可以帮助调试任何问题。
