Dockerfile不从我的initialize.sql创建表

Question

我想这样做customize-your-mysql-database-in-docker

我到了执行docker容器的地步，并向我显示了数据库“ studienarbeit”。但是，当我使用命令show table时，它告诉我数据库中没有表。

所以我认为我的Dockerfile或initializeDB.sql出了问题吗？

Dockerfile：

FROM mysql
ENV MYSQL_DATABASE studienarbeit
COPY ./sql-scripts/ /docker-entrypoint-initdb.d/

InitializeDB.sql：

CREATE TABLE `buchausleihe` (
  `ausleihnummer` int(11) NOT NULL AUTO_INCREMENT,
  `Name` varchar(45) NOT NULL,

问题不是docker，您的SQL文件无效。您可以在文件中创建下面的表，并在脚本的开头引用表。

检查您的Docker容器的日志。
