$ sudo docker run ubuntu:14.10 /bin/echo 'Hello world'
Hello world			
			

进入BASH

$ sudo docker run -t -i ubuntu:14.10 /bin/bash
root@f8c7b2afff14:/# 			
			

start / stop / restart

sudo docker start silly_bohr
silly_bohr

$ sudo docker stop silly_bohr
silly_bohr

$ sudo docker restart silly_bohr
silly_bohr
			

守护进程运行

$ sudo docker run -d ubuntu:14.10 /bin/sh -c "while true; do echo hello world; sleep 1; done"

通过 docker ps 命令来查看容器信息

$ sudo docker ps
CONTAINER ID        IMAGE               COMMAND                CREATED             STATUS              PORTS               NAMES
4cdbb75eeabf        ubuntu:14.10        "/bin/sh -c 'while t   30 seconds ago      Up 28 seconds                           drunk_rosalind 
			

要获取容器的输出信息，可以通过 docker logs 命令。

$ sudo docker logs insane_babbage			
			

注意：守护进程在后台运行，所以无输出，只能通过docker logs 命令查看

$ sudo docker run -idt ubuntu:14.10

$ sudo docker ps

$ sudo docker export 7691a814370e > ubuntu.tar
						
			

			
$ cat ubuntu.tar | sudo docker import - test/ubuntu:v1.0
						
			

指定 URL 或者某个目录来导入，例如

$sudo docker import http://example.com/exampleimage.tgz example/imagerepo			
			

使用 docker rm 来删除一个处于终止状态的容器。

$ sudo docker ps -a
CONTAINER ID        IMAGE               COMMAND                CREATED             STATUS                      PORTS               NAMES
