[docker常见错误]没有vi/vim/nano/怎么办?而且默认源还报错？

只要思想不滑坡，办法总比困难多!
我有好几次遇到docker attach进到容器，没有vi/vim/nano/怎么办?而且默认源还报错？很是心烦

这里给出几种解决方案

1.wget下载vi编辑器手动安装

2.echo命令把源换成国内的，然后apt-get update

mv /etc/apt/sources.list /etc/apt/sources.list.bak
echo 'deb http://mirrors.163.com/debian/ jessie main non-free contrib' > /etc/apt/sources.list
echo 'deb http://mirrors.163.com/debian/ jessie-updates main non-free contrib' >> /etc/apt/sources.list
echo 'deb http://mirrors.163.com/debian-security/ jessie/updates main non-free contrib' >> /etc/apt/sources.list

然后就可以愉快地玩耍了
