【问题标题】：Traefik 2 configured with docker labels and cloudflare https, 404 page not foundTraefik 2 配置了 docker 标签和 cloudflare https，找不到 404 页面
【发布时间】：2020-07-27 22:55:08
【问题描述】：

我无法让 Traefik v2 仪表板（或任何其他服务）通过404 page not found。我试图避免使用traefik.yml 文件并在docker compose 文件中使用command 和labels 配置所有内容。 HTTPS 有效，但内容不显示。

这是定义 traefik 服务的 compose 文件：

version: '3.3'
services:
  traefik:
    image: traefik:v2.2.1
    command:
     - --entrypoints.web.address=:80
     - --entrypoints.websecure.address=:443
     - --providers.docker
     - --providers.docker.swarmmode=true
     - --api
     - --entrypoints.websecure.http.tls.certresolver=myresolver
     - --certificatesresolvers.myresolver.acme.dnschallenge=true
     - --certificatesresolvers.myresolver.acme.email=${CF_API_EMAIL}
     - --certificatesresolvers.myresolver.acme.caserver=https://acme-staging-v02.api.letsencrypt.org/directory
     - --certificatesresolvers.myresolver.acme.storage=acme.json
     - --certificatesresolvers.myresolver.acme.dnschallenge.provider=cloudflare
    labels:
      traefik.http.routers.traefik.tls.certresolver: myresolver
      traefik.http.services.traefik.loadbalancer.server.port: '8080'
      traefik.http.routers.http-catchall.middlewares: redirect-to-https
      traefik.http.middlewares.authtraefik.basicauth.users: user://V6Btlaf2i/ju5n/
      traefik.http.routers.http-catchall.rule: hostregexp(`{host:.+}`)
      traefik.http.routers.traefik.middlewares: authtraefik
      traefik.http.routers.traefik.entrypoints: websecure
      traefik.http.routers.traefik.service: api@internal
      traefik.http.middlewares.redirect-to-https.redirectscheme.scheme: https
      traefik.http.routers.http-catchall.entrypoints: web
      traefik.http.routers.traefik.rule: Host(`traefik.example.com`)
    environment:
      CF_API_EMAIL: ${CF_API_EMAIL}
      CF_API_KEY: ${CF_API_KEY}
    ports:
     - 80:80
     - 443:443
    volumes:

    networks:
     - external
    logging:

    external: true

任何建议都将不胜感激。

标签： docker docker-compose docker-swarm traefik

【解决方案1】：

通过一些更改使其工作：

需要指定网络，因为它是外部的：traefik.docker.network: external
在 swarm 模式下，标签应位于 deploy 下
在 Cloudflare 中，令牌应取自“我的个人资料 > API 令牌 > 全局 API 密钥”

  traefik:
