docker 打包ubuntu和python镜像并提交到仓库
基于ubuntu创建名为docker_ser的容器
更新镜像： apt-get update
安装对应工具包： apt-get install -y vim
更换ubuntu镜像为阿里云
打开配置文件：
cp /etc/apt/sources.list /etc/apt/sources.list.bak
rm /etc/apt/sources.list
vim /etc/apt/sources.list
回车
按 i 进入插入模式

效果图：
退出；
更新镜像
apt-get update
apt-get install -y wget
apt-get install -y openssh-server
apt-get install -y net-tools # ifconfig
apt-get install -y iputils-ping # ping
apt-get install -y gcc
apt-get install -y make
安装python环境
apt-get install -y python3
apt-get install -y python3-pip
apt-get install -y python2.7
apt-get install -y python-pip
测试：
python3
pip3 list
python2
pip2 list
另：如果需要在python3中安装django
pip3 install （-i https://pypi.douban.com/simple）django
ubuntu更换pip源
1、 mkdir ~/.p
2、 cd ~/.p
3、 vi pip.conf
4、写入配置
[global]
timeout = 6000
index-url = https://pypi.douban.com/simple
trusted-host = pypi.douban.com
5、保存退出
打包镜像
docker commit -a '提交人' -m '介绍' 容器名（id） 镜像名称
例：docker commit -a 'zhansan' -m 'installed python2 and python3' docker-sev docker_python
