PermissionError: [Errno 1] docker conatiner 嘗試連接到數據庫時不允許操作

Question

我正在嘗試從以下 docker-compose 文件構建 docker 容器。 除了一個拋出錯誤的容器外，所有容器都已創建並連接到 MySQL 數據庫。 它與其他容器具有相同的權限，並且為數據庫提供了相同的端口，但它不連接到數據庫。 這是來自docker 容器日志的錯誤

該錯誤是由celerybeat: container 拋出的。 我無法理解原因，因為除了這個容器之外，所有容器都成功連接。 可能是什么問題？ 多謝

您應該嘗試使用 sudo 運行 docker-compose。 （如果尚未使用）：

sudo docker-compose up
