Docker - 为root用户配置空密码的mysql

如何解决Docker - 为root用户配置空密码的mysql

我是 docker 新手，并尝试在 Windows 服务器上使用以下命令运行 MysqL 映像。

docker run  -e MysqL_ROOT_PASSWORD=sEe@21 -e MysqL_DATABASE=emp_db -p 3306:3306 --name MysqL_emp MysqL

它已成功下载和配置。我在 CMD 中得到一个日志，上面写着

root@localhost is created with an empty password ! Please consider switching off the --initialize-insecure option.

我已经提供了我设置为应用程序使用的 root 密码，因此我收到一条错误消息，提示无法从 Spring Boot 服务连接到 DB。 MysqL完整日志如下

想了解我做错了什么吗？ docker run 命令中缺少任何参数？

解决方法

如果您按照 MySQL Docker 中心页面上的结构构建运行命令会发生什么：

docker run --name mysql_emp -e MYSQL_ROOT_PASSWORD=sEe@21 -e MYSQL_DATABASE=emp_db -p 3306:3306 -d mysql:latest

如果这不起作用，您可以尝试从 dockerfile 运行，类似于这个问题：MYSQL docker file
