我正在将Traefik配置为在我的开发环境中充当反向代理。我目前有在不同端口和不同PATH上运行的应用程序。
我的环境：
Traefik在主机（192.168.0.10）上运行。侦听端口80、443和8080（traefik仪表板）。
我的应用程序在其他主机（192.168.0.11）上运行。
Web应用程序：192.168.0.11:8200/web1 后端：192.168.0.11：8210 / api1 其他网络应用程序：192.168.0.11:8300/web2 其他后端：192.168.0.11：8310 / api2
我想使用Traefik + LetsEncrypt（acme）通过同一个子域（dev.domain.com）重定向所有这些应用程序。
例如：
当我访问dev.domain.com/web1时，我想将所有访问重定向到192.168.0.11:8200/web1
当我访问dev.domain.com/api1时，我想将所有访问重定向到192.168.0.11:8210/api1
以此类推。
以下是我正在使用的设置，Traefik版本等。

acme目录可以！证书创建没有错误！

当我需要通过Docker（通过标签）将请求重定向到主机上运行的应用程序时，Traefik可以正常工作。我的helloworld.domain.com应用程序正常工作！
当我仅重定向一个应用程序时，Traefik可以正常工作。从在同一个子域中配置第二个应用程序的那一刻起，traefik在通过PATH的重定向中迷路了。
我在互联网上搜索了像我这样的用例，但没有找到使用Traefik来将应用程序重定向到Docker引擎，Kubernetes等外部的人。
答案 0 :(得分：3)
您需要在前端“ AddPrefix：/ myprefix”中添加此参数，并删除后端URL中的路径，如下所示： （url =“ http://192.168.0.11:8200/myprefix”）到（url =“ http://192.168.0.11:8200）
如果您的URL中包含PATH，则只需在前端配置中将此“路径”移至“ AddPrefix”参数即可。
所有其他配置都可以！！
