　　还没时间去练习：

• Docker commands:
  
  
  
  • 
    
    docker images (list all image on this host)
    
  • 
    
    
    
    docker ps -a ( list all containers on this host)
    
  • 
    
    
    
    docker run -t -i centos6_oodee /bin/bash ( create a container with command)
    
  • 
    
    
    
    docker start 091a802729cd ( start one instance of the container).
    
  • 
    
    
    
    
    
    
    
    docker attach 091a802729cd (login the instance)

• Tips to install Docker on Windows
  
  
  
  • Docker only support 64-bit system and for windows Virtualization Technology must be enabled.
    
  
  

　　-To Enable VT,  it should be enabled in BIOS (HP: Press F10,  password : gE51sFqc , Advanced-> Device Configuration)

• For Windows sitting behind a corporate proxy, docker init cannot work properly.
  

　　I got mine to work by adding HTTP_PROXY and HTTPS_PROXY with the correct proxy value into my "System variables" under Environment Variables dialog.

　　7. 使用Dockerfile来启动sshd：
　　7.1 创建Dockerfile,  基于基线image：centos6_oodee，在build新image时，执行如下命令： /usr/sbin/sshd && /bin/bash，这样新image在启动时就可以加载sshd。
　　内容如下：
　　FROM centos6_oodee


            ENTRYPOINT /usr/sbin/sshd && /bin/bash

         7.2在Dockerfile所在目录执行：


docker build -t centos6_oodee_with_sshd .
         7.3创建container：
docker run -t -i centos6_oodee_with_sshd &
         7.4 docker start container后 docker attach 上去top即可看到sshd 已经开启。
