1.下载镜像：
2.新建并启动容器：
Docker run [可选参数] image
容器启动：
Docker run [可选参数] image
#参数说明：
--name="Name" 容器名称 用于区分容
-d 后台方式运行
-it 使用交互模式运行，进入容器查看内容
-p 指定容器端口 -p 3667:3667
-p 主机端口:容器端口
-p 容器端口
-p ip:主机端口:容器端口
-P 随机指定端口
[root@localhost bin]# docker run -it centos /bin/bash
[root@ebc3a0b9a5db /]# ls
bin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var
从容器回到主机：
#Exit 退出并停止容器 [root@localhost bin]# docker run -it centos /bin/bash [root@ebc3a0b9a5db /]# ls bin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var [root@ebc3a0b9a5db /]# exit exit [root@localhost bin]# Ctrl + p +q #容器不停止退出列出所有运行的容器：
