修改主机ip连接到服务器上,服务器是否在主机“localhost”（:: 1）上运行，并接受端口5432上的TCP/IP连接？...

我在使用Ruby on Rail设置和运行本地系统上的docker实例时遇到了问题。请参阅我的搬运工配置文件： -服务器是否在主机“localhost”(:: 1)上运行，并接受端口5432上的TCP/IP连接？

当我运行泊坞窗 - 撰写建和泊坞窗，构成了-d这两个命令它成功运行，但是当我从url中击中它时，它会导致内部服务器错误并且错误是

Unexpected error while processing request: could not connect to server: Connection refused

Is the server running on host "localhost" (127.0.0.1) and accepting

TCP/IP connections on port 5432?

could not connect to server: Cannot assign requested address

Is the server running on host "localhost" (::1) and accepting

TCP/IP connections on port 5432?

我已经应用了一些解决方案，但它不适用于我，请指导我我是码头工人和AWS的新手。

码头日志cluetap_api的输出是什么？我会建议给你的postgres一个容器名如：my-postgres。您可以使用my-postgres：5432从您的api-container连接到您的postgres，因为它们部署在同一个网络中。你甚至不需要映射端口。 –

如果要映射端口，则可以使用server-ip：5432从您的api-container连接。比你的容器不需要在同一个网络内。 –
