docker 镜像下安装Vim

在docker镜像运行以后发现没办法编辑一些配置文件，解决步骤如下：

---

首先，进入docker镜像

    #进入镜像命令
    docker exec -it 镜像Id或镜像name /bin/bash

配置国内镜像源

实际在使用过程中，运行 apt-get update，然后执行 apt-get install -y vim，下载地址由于是海外地址，下载速度异常慢而且可能中断更新流程，所以做下面配置：

    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-proposed-updates main non-free contrib" >>/etc/apt/sources.list
    echo "deb-src http://mirrors.163.com/debian/ jessie main non-free contrib" >>/etc/apt/sources.list
    echo "deb-src http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list
    #更新安装源
    apt-get update

安装vim

    #安装命令
    apt-get install -y vim
