问题描述

我想在kubernetes中创建mysql部署时创建一些mysql用户和数据库.意味着在创建mysql部署时，它还应该在mysql中创建一些用户以及数据库.

以下是我为mysql创建的部署配置.让我知道是否可以在此处添加一些数据来创建用户和数据库.

解决方案

在 mysql docker映像(在初始化新实例"下):您可以使用/docker-entrypoint-initdb.d 作为卷挂载脚本和SQL文件进行数据库初始化的点.>

I wanted to create some mysql users and databases while creating mysql deployment in kubernetes. means when mysql deployment is being created its shouldalso create some users as well as database in the mysql.

解决方案

In the mysql docker image (under "Initializing a fresh instance"): you can use the /docker-entrypoint-initdb.d as a point to which to volume mount scripts and SQL files for database initialization.
