docker - Traefik 2 docker不显示客户端真实IP

问题描述

我在 docker 中运行 traefik（在 Windows 主机上）。我遇到的问题是 X-Real-IP 标头 alawys 显示 docker 网络网关 ip 而不是真正的客户端 ip。我不确定我做错了什么，我知道主机网络模式下的 traefik 应该可以工作，但是它不会再找到它自己的 docker 服务。

这是我的码头工人撰写文件：

    external:

  whoami:

      - "traefik.http.routers.whoami.rule=Host(`whoami.xxx.com`)"
      - "traefik.http.routers.whoami.entrypoints=https"
      - "traefik.http.routers.whoami.tls=true"

我设置了网络：

docker network create --gateway 192.168.90.1 --subnet 192.168.90.0/24 t2_proxy

这是浏览器中 whoami webrequest 的输出：

解决方案

本指南中似乎提供了解决方案：https ://dockerswarm.rocks/traefik/#getting-the-client-ip

如果您需要使用 Traefik 提供的X-Forwarded-FororX-Real-IP标头读取应用程序/堆栈中的客户端 IP，则需要让 Traefik 直接侦听，而不是通过 Docker Swarm 模式，即使在使用 Docker Swarm 模式部署时也是如此。
