nginx轉發配置shipyard遇到的問題

當使用了nginx轉發HTTP請求到shipyard（shipyard.xxx.com）的時候，會發現每個容器的console都用不了,查看錯誤信息(F12)控制檯會打印出這麼一個鏈接 ws://shipyard.xxx.com?exec…. 的400錯誤代碼

我們這裏只轉發了 HTTP轉發,沒有轉發WebSockets 協議，我們需要給nginx配置一個WebSockets 請求

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;
}
