【docker】部署mysql以及连接问题

发现windows上有一个docker descktop(虽然不怎么好用), 安装之后准备直接用docker搭本地测试环境的基础设施(比如MySQL,Redis,MongoDB,ES啥的), 虽然比去到处找安装包安装来的好, 不过这样就体会不到自己装软件的乐趣了(滑稽.jpg)
首先是安装MySQL, 遇到了几个问题, 记录下

mysql镜像用的是最新版的, docker search mysql可以看大很多版本的, 我用的是第一个有官方标注的那个(稳妥)

启动时未指定相关环境变量

docker desktop to specify one of the following:

• -MYSQL_ROOT_PASSWORD
• -MYSQL_ALLOW_EMPTY_PASSWORD
• -MYSQL_RANDOM_ROOT_PASSWORD

docker run -dit --restart always --name mysql-docker -e MYSQL_ROOT_PASSWORD=your-password -p 3308:3306 mysql
注意上面脚本自定义密码是在-e MYSQL_RANDOM_ROOT_PASSWORD=your-password中指定

查看mysql启动时生成的密码

除了通过脚本指定数据库密码之外，mysql启动之后还会生成一个ROOT password

通过密码连接mysql

Public Key Retrieval is not allowed异常
连接时需要设置SSL, docker中的mysql镜像在运行过程中默认开启了SSL
