简易的Docker版本升级方法

1、使用 apt-get

# Add the Docker repository key to your local keychain

 
# Add the Docker repository to your apt sources list.


 
# update your sources list


 
# install the latest

2、手工安装

# kill the running docker daemon

 
 
# get the latest binary


 
# make it executable

# start the new version -d是指以守护进程的方式执行， & 指在后台执行

升级的一次实际操作记录：
# docker ps 查看运行中的docker容器进程
