docker 创建一个容器（前台/后台并指定映射目录和端口）
-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） docker run -d -v /test:/test centos tail -f /dev/null #创建容器并放入后台运行（退出容器不会关闭） docker run -dit -v /test:/test centos /bin/bash #创建容器并放入后台运行（进入后台和tty模式，退出容器不会关闭） docker run -d -v /test:/test -P 80:80 nginx:latest #后台启动并运名为nginx的容器，然后将容器的80端口映射到物理机的80端口. -
