我尝试在版本2中设置Traefik，但我的浏览器中只出现“404 Page not found”或DNS_PROBE_FINISHED_NXDOMAIN错误。
当我检查路由器的API端点时，我可以看到我的两个容器在Traefik中被启用，并且规则是正确的。

curl http://localhost:8080/api/http/routers

[{"entryPoints":["web","secure"],"service":"gotify-gotify","rule":"Host(`sub2.example.org`)","tls":{"certResolver":"letsencrypt"},"status":"enabled","using":["secure","web"],"name":"gotify@docker","provider":"docker"},{"entryPoints":["web","secure"],"service":"nextcloud-cloud","rule":"Host(`sub.example.org`)","tls":{"certResolver":"letsencrypt"},"status":"enabled","using":["secure","web"],"name":"nextcloud@docker","provider":"docker"}]

但是在“sub2”上我根本没有得到任何网站，在“sub”上我得到“404页面找不到”。我已经为“*”设置了一个DNS条目，所以所有子域都到同一个服务器。
我为Docker集装箱设置了以下标签

labels:
traefik.enable: true
traefik.http.routers.nextcloud.rule: "Host(`sub.example.org`)"
traefik.http.routers.nextcloud.entrypoints: "web, secure"
traefik.http.routers.nextcloud.tls.certresolver: "letsencrypt"

这是我的Traefik配置traefik.tom l

[entryPoints]
  [entryPoints.web]
    address = ":80"
  [entryPoints.secure]
    address = ":443"

[providers.docker]
  exposedByDefault = false
  network = "traefik"

[certificatesResolvers.letsencrypt.acme]
  email = "me@example.org"
  storage = "acme.json"
  [certificatesResolvers.letsencrypt.acme.httpChallenge]
    entryPoint = "web"

[api]
  insecure = true
  debug = true
  dashboard = false

Traefik本身是作为码头集装箱运行的。

version: "3.7"

services:
  traefik:
    image: traefik:v2.0
    container_name: traefik
    restart: unless-stopped
    volumes:
    - "./traefik.toml:/etc/traefik/traefik.toml"
    - "./acme:/etc/traefik/acme"
    - "/var/run/docker.sock:/var/run/docker.sock"
    ports:
    - "80:80"
    - "127.0.0.1:8080:8080"
    - "443:443"
    networks:
    - traefik

networks:
  traefik:
    driver: bridge
    name: traefik

我使用ufw来管理防火墙规则，并打开了端口22、80和443

您可以找到traefik 2.2.1的工作示例。此外，您还可以查看完整的设置要点：https://gist.github.com/fatihyildizhan/8f124039a9bd3801f0caf3c01c3601fb
我更喜欢使用2.0版本的traefik.yml。它看起来很简单，很多人都熟悉YAML文件。

有几个原因可能导致这种情况，其中包括：
1.您在DNS级别启用了SSL/TLS代理（例如CloudFlare），这将阻止http质询完成。
1.证书解析程序的存储路径配置错误（可能不是在这种情况下，而是对其他读取器）;检查Traefik container日志docker logs traefik中是否存在

level=error msg="The ACME resolver \"[resolver]\" is skipped from the resolvers 
list because: unable to get ACME account: open /[path_to_storage]/acme.json: 
no such file or directory
level=error msg="the router [service]@docker uses a non-existent resolver: 
[resolver]"

等错误如果您看到这些错误，请确保存储文件夹存在和/或卷已从您的主机正确Map到Traefik docker container（您可能需要手动创建，Traefik不会为您创建，至少目前不会）。
1.代理背后的服务存在技术问题（例如，Nginx、Apache等配置错误）。Traefik将为一系列在技术上与真实的的404错误不对应的错误（例如，500、501，可能是其他错误）生成通用的404 page not found，这可能会引起混淆。
