    #server_name blog.zeroxzed.ru;
    #access_log /var/log/nginx/blog.zeroxzed.ru-access.log;
    #error_log /var/log/nginx/blog.zeroxzed.ru-error.log;

location / {
    proxy_pass http://172.23.0.3:3000;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Real-IP $remote_addr;
    }
