Docker容器apt-get update更新慢

一、进入容器

#查询容器
docker ps

#其中96656852148f为容器编号
docker exec -it 96656852148f /bin/bash

二、备份源

cp /etc/apt/sources.list /etc/apt/sources.list.bak

三、清空源

echo > /etc/apt/sources.list

查看源是否清空

cat /etc/apt/sources.list

四、写入新源

向/etc/apt/sources.list文件中，写入源地址

echo  "deb http://mirrors.tuna.tsinghua.edu.cn/debian/ buster main contrib non-free" >/etc/apt/sources.list
echo  "deb http://mirrors.tuna.tsinghua.edu.cn/debian/ buster-updates main contrib non-free" >>/etc/apt/sources.list
echo  "deb http://mirrors.tuna.tsinghua.edu.cn/debian/ buster-backports main contrib non-free" >>/etc/apt/sources.list
echo  "deb http://mirrors.tuna.tsinghua.edu.cn/debian-security buster/updates main contrib non-free" >>/etc/apt/sources.list

五、更新

apt-get update

六、安装工具

apt-get install wget

apt-get install python3-pip
