Status: Downloaded newer image for mysql:5.7下载需要一段时间，下载完毕后，启动Docker容器。3、先查看本机都有哪些镜像，命令如下：docker images然后会打印出以下日志：? REPOSITORY? ? ? ? ? TAG? ? ? ? ? ? ? ? IMAGE ID? ? ? ? ? ? CREATED? ? ? ? ? ? VIRTUAL SIZE? mysql? ? ? ? ? ? ? 5.7? ? ? ? ? ? ? ? fdb9c2185fc2? ? ? ? 9 days ago? ? ? ? ? 321.9 MB? csphere/csphere? ? 0.11.2? ? ? ? ? ? ? 6d983828b938? ? ? ? 8 weeks ago? ? ? ? 112 MB4、然后启动我们的mysql的docker容器，命令如下：? docker run --name db001 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=mytest -d mysql:5.7注意，这里的容器名字叫：db001，mysql的root用户密码是：mytest，映射宿主机子的端口3306到容器的端口3306，仓库名mysql和标签(tag）唯一确定了要指定的镜像，其实如果这里只有一个mysql也有必要要tag，执行该命令返回的结果是：a40c6e58afbda0199111a2a2ef0af7e8dd9be057a610ca5f4f30aa782a5d91555、查看已经运行的的所有容器，命令如：dockerps返回的结果是：?
