使用dockerfile 构建自己的nacos-mysql

前言

在部署nacos的时候触发的脑袋灵光一闪，每次部署nacos都要部署下mysql服务器，然后导入sql语句，配置nacos配置文件，那有没有简单的方法实现一键部署nacos和nacos-mysql 呢?

答案是肯定！如下目录图：

我用的IDE是 Idea 2023

源码下载地址：docker-mysql-master

使用dockerfile 构建自己的nacos-mysql-LMLPHP

1、编写dockerfile

mysql属于oracle 当然要orcale的镜像喽！

下面代码是官方提供的代码我们需要稍微的改动一下文件添加下面这句话复制init.sql到

/docker-entrypoint-initdb.d/

COPY init.sql /docker-entrypoint-initdb.d/

/docker-entrypoint-initdb.d/ 解释：

/docker-entrypoint-initdb.d/ 是一个特殊的目录，用于在 Docker 容器启动时运行 SQL 脚本初始化数据库。任何位于该目录下的文件都会在容器启动时被 Docker 引擎执行。这个目录通常用于初始化数据库或设置默认密码等操作。这个功能是为了一些初始化操作可以在容器启动时自动完成，避免了手动登录容器进行初始化的步骤
