Traefik：所有子目录都返回 404

如何解决Traefik：所有子目录都返回 404

首先，提前感谢您的观看。我想我在某处犯了一个非常基本的错误，但我已经搜索了几个小时没有结果。我正在尝试运行概念验证以在子目录中的 traefik 2.4 反向代理后面公开容器。我的 DDNS 不允许使用子域，所以我一直在使用子目录，直到我能证明它有效。

我的问题是我站起来的每个容器都被 traefik 动态拾取并显示在仪表板中，但是子目录给出了 404 错误。我什至使用 PathPrefix 和正则表达式来防止结束/错误。

这是我的配置。

Traefik 的 docker-compose：

version: '3'

services:
        traefik:
                image: traefik:v2.4
                container_name: traefik
                restart: unless-stopped
                security_opt:
                        - no-new-privileges:true
                networks:
                        - t2_proxy
                ports:
                        - 80:80
                        - 443:443
                volumes:
                        - /etc/localtime:/etc/localtime:ro

                        - ./data/acme.json:/acme.json
                        - ./data/log:/var/log

                labels:
                        - "traefik.enable=true"
                        - "traefik.http.routers.traefik.entrypoints=http"
                        - "traefik.http.routers.traefik.rule=Host(`domain.host.com`)"

                        - "traefik.http.routers.traefik-secure.rule=Host(`domain.host.com`)"
                        - "traefik.http.routers.traefik-secure.middlewares=traefik-auth"
                        - "traefik.http.routers.traefik-secure.tls=true"
                        - "traefik.http.routers.traefik-secure.tls.certresolver=http"
                        - "traefik.http.routers.traefik-secure.service=api@internal"

        fail2ban:
                image: crazymax/fail2ban:latest
                container_name: fail2ban
                network_mode: "host"
                cap_add:
                        - NET_ADMIN
                        - NET_RAW
                volumes:
                        #                        - /var/log:/var/log:ro
                        - ./fail2ban/data:/data
                        - ./data/log:/var/log:ro
networks:
        t2_proxy:
                external: true

这是我的 traefik.yml 配置文件：

api:
        dashboard: true

entryPoints:
        http:
                address: ":80"
        https:
                address: ":443"

providers:
        docker:
                endpoint: "unix:///var/run/docker.sock"
                exposedByDefault: false

certificatesResolvers:
        http:
                acme:
                        email: email@email.com
                        storage: acme.json
                        httpChallenge:
                                entrypoint: http

log:
        filePath: "/var/log/traefik.log"
        level: DEBUG
accessLog:
        filePath: "var/log/access.log"
        filters:
                statusCodes:
                        - "400-499"
                retryAttempts: true

这是我尝试公开的第一个概念验证容器。它只是一个单独的 docker-compose 中的 portainer：

version: '3'

services:
        portainer:
                image: portainer/portainer-ce:latest
                container_name: portainer
                restart: unless-stopped
                security_opt:
                        - no-new-privileges:true
                networks:
                        - t2_proxy
                ports:
                        - "9000:9000"
                volumes:
                        - /etc/localtime:/etc/localtime:ro
                        - /var/run/docker.sock:/var/run/docker.sock:ro
                        - ./data:/data
                labels:
                        - "traefik.enable=true"

                        - "traefik.http.routers.portainer-secure.tls=true"
                        - "traefik.http.routers.portainer-secure.tls.certresolver=http"
                        - "traefik.http.routers.portainer-secure.service=portainer"
                        - "traefik.http.services.portainer.loadbalancer.server.port=9000"
                        - "traefik.docker.network=t2_proxy"
networks:
        t2_proxy:
                external: true

总而言之，我导航到 domain.host.com，它通过将我重定向到 domain.host.com/dashboard 来正常运行。但是，当我访问 domain.host.com/portiner 时，它会出现 404 错误。

如果我应该发布任何其他详细信息，请告诉我。我感觉我遗漏了一些非常明显的配置，因为这是我第一次使用 Traefik。再次感谢您的帮助！

解决方法

对于未来的谷歌员工

好的，我今晚想通了。感谢 reddit.com/traefik 用户 /u/Quafeinum 的帮助！我实际上在这里阅读了指南：https://spad.uk/practical-configuration-of-traefik-as-a-reverse-proxy-for-docker/ by spad on linuxserver.io 这帮助我更好地理解了标签。问题的关键是

traefik.http.services.whoami-whoami.loadbalancer.server.scheme=https

不管它做什么，它都出现在所有示例中，我无意识地复制了它（这里有一个警示故事）。删除它后，容器现在可以在 HTTPS 上正确公开。已通过 portainer 和 whoami 验证。

这是指向相关 docker-composes 和 yamls 的 pastebin 的链接。这将得到一个功能正常的 traefik，它通过 HTTPS 动态加载 docker 容器 whoami。
