退出容器，在宿主机环境中，编辑 Nginx 配置文件。

1. 编辑 nginx 配置文件
   vim /etc/nginx/nginx.conf

2. 在 Server 节点 平级 添加如下内容
   注意 server_name 处替换为你所使用的域名。

   map $http_upgrade $connection_upgrade {
   default upgrade;
   ''   close;
   }
   
   server{
        listen 80;
        listen [::]:80;
   
        server_name kf-api.yourname.com;
   
        location / {
                   proxy_pass http://localhost:8021;
                   proxy_http_version 1.1;
                   proxy_set_header Upgrade $http_upgrade;
                   proxy_set_header Connection $connection_upgrade;
                   proxy_set_header Host $host;
                   proxy_cache_bypass $http_upgrade;
                   proxy_set_header X-Forwarded-For $remote_addr;
        }
   }
   
   server{
        listen 80;
        listen [::]:80;
   
        server_name kf-resource.yourname.com;
   
        location / {
                   proxy_pass http://localhost:8022;
                   proxy_http_version 1.1;
        }
   }
   
   server{
        listen 80;
        listen [::]:80;
   
        server_name kf-m.yourname.com;
   
        location / {
                   proxy_pass http://localhost:8023;
                   proxy_http_version 1.1;
        }
   }
