Docker zeppelin + Docker openresty

目前我正在尝试将 Nginx（Openresty 版本）放在 Apache Zeppelin 前面 - 两者都是 Docker 镜像。当我尝试为 WebSocket 做此操作时，会收到 405 错误。如果我直接访问 Zeppelin 的 WebSockets，则可以正常工作；但是如果我尝试使用 Openresty 进行代理，则会失败。

请提供一个解决方案。谢谢提前。

以下是 nginx.conf 的配置文件：

worker_processes  1;
error_log /dev/stderr warn;

events {
    worker_connections 1024;
}
