1、在docker环境下，使用vi编辑文件，vi conmmond not found

apt-get update
apt-get install vim

 2、回到宿主机

进入/etc/docker 

在此目录下 使用 touch daemon.json命令创建daemon.json文件

touch daemon.json

{
    "dns": ["8.8.8.8", "114.114.114.114"]
}

// 重启docker
systemctl restart docker
// 启动docker容器
docker exec -it xxx bin/bash

3、执行apt-get update命令可能出错如下：

The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 3B4FE6ACC0B21F32

执行apt-key adv添加，再遇到同样添加即可

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3B4FE6ACC0B21F32

4、docker容器内进入/etc/apt/目录

// 进入apt目录
cd /etc/apt/
// 备份 source.list
cp source.list source.list2
// 执行下面命令添加apt镜像源
echo "deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse" >> /etc/apt/sources.list
echo "deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse" >> /etc/apt/sources.list
echo "deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse" >> /etc/apt/sources.list
echo "deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse" >> /etc/apt/sources.list
echo "deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse" >> /etc/apt/sources.list
echo "deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse" >> /etc/apt/sources.list
echo "deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse" >> /etc/apt/sources.list
echo "deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse" >> /etc/apt/sources.list
echo "deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse" >> /etc/apt/sources.list
echo "deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse" >> /etc/apt/sources.list

5、再次执行，一次不行就两次，

apt-get update
apt-get install vim
