我在Ubuntu 18.04上做了这些。我无法理解为什么会发生这种情况以及如何解决这个问题。有人能帮忙吗？您应该首先检查您是否能够从运行docker的主机上解析
deb.debian.orgnslookup deb.debian.orgdig deb.debian.org名称服务器8.8.8.8/etc/resolv.conf/etc/resolv.conf/etc/docker/daemon.json{
"dns": ["8.8.8.8"]
}
$ service docker restart
看起来您的docker无法正确解析主机。要检查docker是否能够解析DNS，请执行以下命令。在某些环境中，网络管理员可能会阻止8.8.8.8。如果8.8.8.8被阻止，请使用您的本地DNS IP
sudo docker run busybox nslookup google.com
sudo docker run --dns 8.8.8.8 busybox nslookup google.com
{
"dns": ["8.8.8.8"]
}
service docker restart
sudo docker run busybox nslookup google.com
我在套接字上遇到权限错误，导致DNS无法工作<代码>sudo apt get purge--本文中的自动删除apparmor最终为我解决了这个问题。Ubuntu-buster。这并没有解决根本问题，但我成功地将
--network=hostsudo docker build--network=host-t ics image。/etc/resolve.conf
