Kubernetes uses nginx to reverse proxy other services

The company uses K8S to build a test environment, and there are multiple sets of test exchanges. The current idea is to use an export IP for each set of test environment.
The plan:
1. Build ingress
2. Build a reverse agent

Combined with the actual situation, we use to build a reverse agent to solve this problem.

The following K8S services exist in our environment
Vipapi mall COM based on. netcore
Billapi mall COM based on PHP
www-mall-com - PHP based
Mobile mall COM based on VUE

The external domain name of vipapi-mall-com is vipapi.mall.com.
billapi-mall-com the external domain name is billapi.mall.com

kubernetes's Kube DNS address is, using coredns
We have the following namespace

The configuration file is as follows:

     upstream vipapi {
        server vipapi-mall-com;     #Under normal circumstances, it will be wrong to put it here, but if you add restover, it will not be wrong. Just fill in the service name of K8S here.
     server {
        listen       80;
        server_name  vipapi.mall.com;
        access_log off;
        resolver;        #Note that the configuration of DNS resolution must be placed under the server and not under the location, otherwise it cannot be resolved.
        location / {
             proxy_http_version 1.1;
