Ubuntu中docker容器运行apt-get update失败 Err:1 http://archive.ubuntu.com/ubuntu xenial InRelease

在用virtualBox安装的Ubuntu上运行docker容器，在容器中使用apt-get update一直报错，

Err:1 http://security.ubuntu.com/ubuntu xenial-security InRelease
  Temporary failure resolving 'security.ubuntu.com'
Err:2 http://archive.ubuntu.com/ubuntu xenial InRelease

在网上找了很多解决方案都没成功，自己最后通过查看Ubuntu虚拟机网络中DNS，将DNS配置到Docker 中/etc/resolv.conf文件中，成功运行apt-get update

查看cat /etc/resolv.conf配置文件

cat /etc/resolv.conf

查看Ubuntu虚拟机上system网络中的DNS

将该DNS写入到docker运行容器中DNS文件

echo "nameserver 150.236.34.180" | tee /etc/resolv.conf > /dev/null
root@29031ce31df6:/# cat /etc/resolv.conf
nameserver 150.236.34.180

运行apt-get update

apt-get update
