Ubuntu docker容器上没有internet访问

我刚刚在虚拟机上安装了docker，并创建了一个ubuntu容器。当我运行“apt update”时，我得到以下错误

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

我已经尝试让/etc/default/DOCKER中的DOCKER_OPTS使用谷歌的DNS并重新启动了DOCKER，但没有成功

我也试过：

pkill docker
iptables -t nat -F
ifconfig docker0 down
brctl delbr docker0
docker -d

我怎样才能解决这个问题？

已经解决了。我所要做的就是把这篇文章注释掉

dns=dnsmasq

位于

/etc/NetworkManager/NetworkManager.conf

中的条目您对

DOCKER\u OPTS

做了哪些更改？您如何验证更改是否处于活动状态？使用

ps

验证Docker守护进程是否正在使用您配置的选项运行，并查看容器中的

/etc/resolv.conf

，查看

名称服务器设置是否正确。
