1.docker build “temporary failure resolving deb.debian.org”
解决：
修改docker daemon配置文件，使其使用国际通用的114/8地址

sudo vim /etc/docker/dameon.json

加入DNS配置

{
  "registry-mirrors": ["https://阿里分配的地址.mirror.aliyuncs.com"],
  "dns":["114.114.114.114","8.8.8.8"]
}

重启docker服务

systemctl daemon-reload
systemctl restart docker

2.docker build “temporary failure resolving deb.debian.org”

解决办法：
修改docker daemon配置文件，修改iptables 配置false 改为true

 vim /etc/docker/dameon.json
 {
  "registry-mirrors": ["https://阿里分配的地址.mirror.aliyuncs.com"],
  "dns":["114.114.114.114","8.8.8.8"],
  "iptables": true
}

3. apt-get update -y 安装报错

E: Repository 'https://mirrors.tuna.tsinghua.edu.cn/debian buster-updates InRelease' changed its 'Suite' value from 'stable-updates' to 'oldstable-updates'

解决办法：

sudo apt-get --allow-releaseinfo-change update -y
