nginx - 将 nginx 代理到另一个 nginx，然后再到应用程序

Question

我有以下设置。

网络 A Nginx / SSL

Network B App1/preprod（keycloak preprod、wildfly preprod、database preprod）

网络 C Nginx /SSL

Network D App1/test（keycloak测试、wildflys测试、数据库测试）

沟通：

A <-> B
A <-> C
C <-> D

我在尝试着：

NGINX A -> APP 1 preprod --- that is ok
NGINX A -> NGINX C -> APP 1 test --- that's what i am tryng to figure out.

问题是 APP1 测试中的 keycloak 需要从 NGINX A URL 而不是 NGINX C 获取请求。

我感谢你的帮助，

艾伦

It's little bit difficult to understand actual problem here.

I assume you should dig into http headers while passing through nginx. You could pass same Host header even hostname does not resolve to Nginx C. Just use upstream in proxy_pass and set proxy_set_header Host parameter with desired value.
