#Docker Run [Option] 用法

Sudo docker run [Option] [Image] [Command] [Arg](Ex : Sudo docker run --rm -d alpine sleep 10)(Ex : Sudo docker run -it alpine /bin/sh)Option-d 将Container跑在背景 (不会卡死terminal)-e 设置环境参数-i 保持STDIN开启-t 开启pseudo-TTY (通常-it连用)--name 给Container一个别名--p 将Container中的Port对应到本机的Port--rm 在Container停止后自动删除-v 将Container内的资料夹与本机的资料夹做映射!
