Dockerfile
运行一个ubuntu容器
docker run -i -t ubuntu /bin/bash
备份apt源
cp /etc/apt/sources.list /etc/apt/sources.list.bak
修改apt源
vi /etc/apt/sources.list
替换所有源为sohu源

修改保存后退出运行的容器
exit
查看最后一个运行的容器
docker ps -l
提交本次修改的镜像为 ubuntu/sohu
docker commit 698 ubuntu/sohu
使用修改后源的镜像做Dockerfile

需要注意：
- ENTRYPOINT，表示镜像在初始化时需要执行的命令，不可被重写覆盖，需谨记
- CMD，表示镜像运行默认参数，可被重写覆盖
- ENTRYPOINT/CMD都只能在文件中存在一次，并且最后一个生效 多个存在，只有最后一个生效，其它无效！
- 需要初始化运行多个命令，彼此之间可以使用 && 隔开，但最后一个须要为无限运行的命令，需切记！
构建镜像
#. 代表Dockerfile在当前路径下
docker build -t shawn/ssh .
