Kubernetes nginx reverseproxy how to deploy any examples?

Question

Nginx

Hello. I'm trying to deploy nginx reverseproxy in K8s. I have dotnet pods, I want to proxy them through nginx reverse proxy
. I don't understand how to do it.
Here is the config.
configmap
nginx.conf

apiVersion: v1
kind: ConfigMap
metadata:
  name: nginx
data:
  nginx.conf: |
    worker_processes 4;

    events { worker_connections 1024; }

    http {
        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;
        default_type application/octet-stream;
        gzip on;

    upstream hosts {
             server ip:port;
             server ip:port;
                }
    server {
        listen 80;
        location / {
        proxy_pass http://hosts;
        proxy_http_version 1.1;
        proxy_set_header   Upgrade $http_upgrade;
        proxy_set_header   Connection keep-alive;
        proxy_set_header   Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;
         }

         }


         }
