最近业务使用k8s集群经常有两个问题需要解决，这里记录一下：
- 前端页面上传文件1M限制
- 前端页面发送POST请求到后端，出现504超时
第一个问题主要解决方法：nginx默认上传大小为1M，nginx配置文件http,server, location区域增加如下内容：
1
| client_max_body_size 800M;
|
第二个问题主要解决方法：nginx默认读取后端超时时间为1分钟，nginx配置文件http,server, location区域增加如下内容：
1
2
3
| proxy_connect_timeout 120;
proxy_read_timeout 900;
proxy_send_timeout 900;
|
最终，nginx配置如下：

}

最后，以上nginx配置调整以后，还需要在创建ingress的时候，注解里带上这些信息：
