如何使用Ingress代理kubernetes外部URL地址? 在使用nginx作为代理之前,配置如下。
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
是kubernetes之外的服务。
如何在入口中实现上述nginx配置代理的效果?

这是Google Cloud上的一篇不错的文章,内容涉及如何为外部端点创建服务:https://cloud.google.com/blog/products/gcp/kubernetes-best-practices-mapping-external-services
然后,您需要添加的就是带有您配置的新服务和端口的规则条目。至于kubernetes的处理方式,它将返回一个DNS名称/ IP(取决于您为端点配置的方法,然后据我所知,入口将像处理其他请求一样处理该问题。
希望这会有所帮助。
