How can I use ingress to proxy a kubernetes external url address? Before I used nginx as a proxy, the configuration is as follows.

       location /index.html {
            proxy_next_upstream http_502 http_504 error timeout invalid_header;
            proxy_pass  http://172.19.2.2:8080/index.html;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_intercept_errors off;
            proxy_connect_timeout 900000;
            proxy_send_timeout 900000;
            proxy_read_timeout 900000;
            add_header Cache-Control 'no-cache';
            add_header Access-Control-Allow-Origin *;
            add_header 'Access-Control-Allow-Headers' 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
       }

http://172.19.2.2:8080/index.html Is a service outside of kubernetes。

How can I achieve the effect of the above nginx configuration proxy in ingress?
