Question

我正在Digital Ocean Droplet上部署Angular-Django应用程序。它由3个Docker容器组成：

cards_front：Angular前端
cards_api：Django rest框架后端
cards_db：postgres数据库

它们都在同一个网络上

    }
}

django设置上的ALLOWED_HOSTS设置为['*']

在浏览器上测试Angular前端时，我会使用Chrome的开发人员工具：

GET http://localhost:8000/themes net::ERR_CONNECTION_RESET

因此，Angular容器无法与django容器通信。

但是，如果我从DO液滴内部执行curl localhost：8000 / themes，则会收到响应。

我知道网络配置中缺少某些内容，但是我无法弄清楚它是什么。

谢谢

编辑：

如果我从Angular容器内部到django容器进行卷曲，则会收到响应（空数组）：

root@90cea47dd13d:/# curl 172.22.0.3:8000/themes
[]

Docker-同一网络上的容器之间的通信失败
