upstream engine.app {
    server engine:8000;
}
server {
    listen 80;
    server_name engine.app;
    location / {
        proxy_pass http://engine.app;
        proxy_set_header Host "localhost";
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_redirect off;
    }
}

upstream parser.app {
    server parser:8000;
}
server {
   listen 80;
   server_name parser.app;
   location /parser {
       proxy_pass http://parser.app;
       proxy_set_header Host "localhost";
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       proxy_redirect off;
   }
}

给定此nginx配置
当server_ip/engine和server_ip/engine/route1工作时，我无法在server_ip/parser上公开解析器服务。
我有两个Docker服务parser:8000和engine:8000。最后，我想把解析器：8000服务公开到互联网上，就像对引擎一样。
请告知。
