mysql - Docker LAMP 镜像 mysql 连接问题

Question

我试图创建 docker LAMP 堆栈映像并遇到一些与数据库连接有关的问题。运行容器后，我可以在本地主机上点击静态页面，告诉我实际图像很好，但我不知道为什么数据库没有连接。我正在使用 aws db，它在我的本地灯环境中运行良好。但是 contianer 图像有问题。

环境

export DS_ENVIRONMENT="local"

export DS_DB_USER="db_user"
export DS_DB_PASS="xxxxxxx"

当我运行此容器时，出现以下错误：

致命错误：在 /var/www/html/vendor/illuminate/database/Connectors/Connector.php:68 中带有消息“SQLSTATE[HY000] [2002] No such file or directory”的未捕获异常“PDOException” 堆栈跟踪：#0 /var/www/html/vendor/illuminate/database/Connectors/Connector.php(68): PDO->__construct('mysql:host=loca...', 'root', 'root', Array) #1 /var/www/html/vendor/illuminate/database/Connectors/Connector.php(45): Illuminate\Database\Connectors\Connector->createPdoConnection('mysql:host=loca...', 'root', 'root ', Array) #2 /var/www/html/vendor/illuminate/database/Connectors/MySqlConnector.php(24): Illuminate\Database\Connectors\Connector->createConnection('mysql:host=loca...',数组，数组）#3 /var/www/html/vendor/illuminate/database/Connectors/ConnectionFactory.php（183）：Illuminate\Database\Connectors\MySqlConnector->connect(Array) #4 [内部函数]: Illuminate\Database\Connectors\ConnectionFactory->Illuminate\Database\Connectors{closure}() #5 /var/www/html/vendor/ Illuminate/database/Connection.php(883): call_user_func(Object(C in /var/www/html/vendor/illuminate/database/Connectors/Connector.php 在第 68 行

我似乎无法确定这是从哪里来的。显然看起来像一个 db 连接问题，但 1）我不明白为什么它使用图像中看到的 localhost 连接字符串。这是默认的吗？
