MySQL

基本信息

MySQL 是开源的关系数据库实现。

该仓库位于 https://hub.docker.com/_/mysql/，提供了 MySQL 各个版本的镜像，包括 5.6 系列、5.7 系列等。

使用方法

默认会在 3306 端口启动数据库。

$ docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=mysecretpassword -d mysql

之后就可以使用其它应用来连接到该容器。

$ docker run --name some-app --link some-mysql:mysql -d application-that-uses-mysql

或者通过 mysql。

$ docker run -it --link some-mysql:mysql --rm mysql sh -c 'exec mysql -h"$MYSQL_PORT_3306_TCP_ADDR" -P"$MYSQL_PORT_3306_TCP_PORT" -uroot -p"$MYSQL_ENV_MYSQL_ROOT_PASSWORD"'
