docker - Traefik背后的Apache Nifi作为反向代理

Question

我将Traefik用作许多服务和tls终止的反向代理。除Nifi之外，此功能均正常运行。尝试将传入请求转发到Nifi时，我收到“错误的网关”响应。
有人知道如何解决这个问题吗？

非常感谢 :-)

  - "traefik.http.routers.nifi.middlewares=nifi-auth"
  # Basic Auth
  - "traefik.http.middlewares.nifi-auth.basicauth.users=admin:$$xyz$$xyz$$xyz"

任何的想法？？ :-)

由于为ui等打开了多个端口，因此需要使用(例如)定义路由端口:

 - "traefik.http.services.nifi.loadbalancer.server.port=8080"
