PathPrefixStrip不能按预期重定向到后端

Question

问题

最近，我决定从Swarm迁移到Kubernetes，并一直在尝试配置Traefik以将我的请求路由到基于Path的预期后端服务。

在阅读了文档和其他一些主题之后，即使在StackOverflow上，我也得出结论，到达那里的正确选择是使用 PathPrefixStrip ，例如：

  

如果后端侦听根路径（/），但应在特定前缀上可路由，请使用* Strip匹配器。例如，PathPrefixStrip：/ products可以匹配/ products，也可以匹配/ products / shoes和/ products / shirts。由于路径是在转发之前剥离的，因此您的后端应该在/上侦听。

但是显然，我仍然缺少一些东西。

您期望看到什么？

对objectB = { birthdate: 'mybirthdate', school: 'myschool', age: 'myage' } 的请求在http://192.168.1.230/blog

上重定向到后端服务“无论它在哪里”

您看到了什么？

相反，我得到/ 404's或http://192.168.1.230/blog或其他任何东西。

版本 我尝试了Traefik 1.7和Kubernetes v1.12.2

谢谢你们，对不起，如果我错过了一些东西，问了一个假的问题。
