我正在嘗試為使用 Postgres 作為資料庫的 Hanami Web 應用程式設定多服務 docker 環境。我正在關注 Docker 和其他資源來這樣做。我目前有兩個服務：postgres 和 app。我平移為 nginx 添加一個單獨的。在我運行docker-compose up“似乎”一切正常之后，但是在我訪問本地瀏覽器中的 url 之后，我得到了關于 Postgres 的錯誤。
以下是每個檔案的所有詳細資訊：

我比較了通過 docker 運行時的終端輸出或從我的應用程式根目錄啟動的普通服務器。
碼頭工人輸出：
web_1 | * Listening on http://0.0.0.0:2300
本地機器上的應用服務器輸出：
* Listening on http://127.0.0.1:2300
* Listening on http://[::1]:2300
這可能是問題嗎？
uj5u.com熱心網友回復：
不要將您的連接稱為 localhost
Cannot assign requested address Is the server running on host "localhost"
從您的應用程式中參考您在 docker 中作業的容器名稱，該名稱db
具有自己的網路，因此當您使用時，localhost您正在參考您的應用程式未在其上運行的主機網路
