-i：允许我们对容器内的 (STDIN) 进行交互
-t：在新容器内指定一个伪终端或终端
-v：是挂在宿机目录， /docker_test是宿机目录，/yufei是当前docker容器的目录，宿机目录必须是绝对的。
--name：是给容器起一个名字，可省略，省略的话docker会随机产生一个名字
-P 指定映射的端口
--net #指定网络
--link 链接到另一个容器
--------------------------------------------------------------------------------------------------
docker run -it -v /test:/test  --name centos /bin/bash #创建容器并进入（交互模式退出会后容器会自动关闭）
