docker - Traefik 背后的 Apache Nifi 作为反向代理

问题描述

我使用 Traefik 作为许多服务和 tls 终止的反向代理。这可以正常工作，但 Nifi 除外。尝试将传入请求转发给 Nifi 时，我收到“错误网关”响应。有人知道如何解决这个问题吗？

非常感谢 ：-）

traefik:
image: "traefik:v2.2"

nifi:
image: apache/nifi:latest
container_name: nifi
restart: on-failure
environment: 
  - NIFI_WEB_PROXY_CONTEXT_PATH=/
  - NIFI_WEB_HTTP_PORT= 8080
expose:
  - 8080
networks: 
  - iot
labels:
  - "traefik.enable=true"
  - "traefik.http.routers.nifi.rule=Host(`nifi.example.de`)"
  - "traefik.http.routers.nifi.entrypoints=web"

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

任何想法？？:-)

解决方案

由于为 ui 等打开了几个端口，因此需要使用（例如）定义路由端口：

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