nginx转发配置shipyard遇到的问题

当使用了nginx转发HTTP请求到shipyard（shipyard.xxx.com）的时候，会发现每个容器的console都用不了,查看错误信息(F12)控制台会打印出这么一个链接 ws://shipyard.xxx.com?exec…. 的400错误代码

我们这里只转发了 HTTP转发,没有转发WebSockets 协议，我们需要给nginx配置一个WebSockets 请求

map $http_upgrade $connection_upgrade {
        default upgrade;
        ''      close;
 }
server {
    listen 80;
    server_name shipyard.xxx.com;
    location / {
        proxy_redirect off;
        proxy_pass http://xxx.com:8000;

        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_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
    access_log  /var/log/nginx/shipyard.access.log  main;
    error_log  /var/log/nginx/shipyard.error.log warn;
}
