docker 安装vim

1. apt-get install vim

提示：

        Reading package lists... Done
        Building dependency tree       
        Reading state information... Done
        E: Unable to locate package vim

2. apt-get update

需要更换docker debian中apt-get源替换为阿里源和清华源

cp /etc/apt/sources.list /etc/apt/sources.list.bak ; # 先备份
echo " " > /etc/apt/sources.list ;　# 清空文件
echo "deb http://mirrors.aliyun.com/debian jessie main" >> /etc/apt/sources.list ;
echo "deb http://mirrors.aliyun.com/debian jessie-updates main" >> /etc/apt/sources.list ;
echo "deb https://mirrors.ustc.edu.cn/debian jessie-updates main" >> /etc/apt/sources.list ;

可能会出的问题：The following signatures couldn't be verified because the public key is not available: NO_PUBKEY xxxxxxxx（'公钥编码'）

解决方法：将公钥添加至服务器，即终端中输入：

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys '公钥编码'

添加成功后终端输出为

gpg: key '公钥编码': public key "xxxxxx" imported

gpg: Total number processed: 1

gpg:                        imported: 1

3. 等更新完毕以后再敲命令：apt-get install vim命令即可。
