基本上，我正在运行一个具有以下堆栈的webapp:
The backend is connecting to the database via localhost, and is being served on the public ip
I can access it at just fine at mydomain.com:8000/api
然而，当我try 访问mydomain.com时，docker设置为将端口3000转发到端口80，但它无法请求react，我得到ERR_CONNECTION_REFUSED错误
在许多类似的问题中，人们忘记将端口3000转发到80，但我正在这样做...
此外，当我安装npm&；我的Ubuntu服务器上的react项目，前端可以通过mydomain.com:3000访问
在docker compose中.当我将端口从"REACT\u PORT:80"更改为"3000:3000"，并且可以通过我们的公共ip访问时，yml.
我是否应该在主linux服务器上向前移植3000到80？如何做？
