docker能够应用上面的命令获取镜像：
docker pull mysql:5.7查找镜像
能够应用上面的命令获取以后下载的所有镜像：
docker images集体获取到的镜像内容如下：
[zxd@localhost seata]$ docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEredis latest 0256c63af7db 5 days ago 117MBmysql 5.7 d410f4167eea 2 weeks ago 495MBredis <none> 3e12e2ceb68f 2 weeks ago 117MBapache/rocketmq 4.9.4 a2a50ca263c3 5 months ago 548MBapacherocketmq/rocketmq-dashboard latest eae6c5db5d11 14 months ago 738MBhello-world latest feb5d9fea6a5 15 months ago 13.3kB本地创立mysql的映射目录
在正式的启动Mysql镜像之前进行映射目录的配置。
mkdir -p /opt/mysql/data /opt/mysql/logs /opt/mysql/conf在/root/mysql/conf中创立 *.cnf 文件（叫什么都行）。这里以集体创立的mysql.conf为例：
touch mysql.conf创立容器，将数据，日志,配置文件映射到本机，留神这里的root明码为root：
docker run -p 13306:3306 --name mysql -v /opt/mysql/conf:/etc/mysql/conf.d -v /opt/mysql/logs:/logs -v /opt/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7运行之后，咱们执行docker ps查看以后运行的mysql镜像：
[zxd@localhost conf]$ docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESe95a0bc7b4a4 mysql:5.7 "docker-entrypoint.s…" About a minute ago Up About a minute 33060/tcp, 0.0.0.0:13306->3306/tcp, :::13306->3306/tcp mysql相干运行参数如下：
-d: 后盾运行容器
-p 将容器的端口映射到本机的端口
-v 将主机目录挂载到容器的目录
-e 设置参数
运行之后咱们执行上面的命令查看：
