我正在运行一个kind集群并部署了一个ubuntu pod
kubectl run ubuntu -test——rm -i——tty——image ubuntu——bash
然后我尝试在shell上运行apt-get update。输出为

Get:2 http://archive.ubuntu.com/ubuntu jammy InRelease
Get:3 http://archive.ubuntu.com/ubuntu jammy-updates InRelease

现在，当我使用docker运行ubuntu容器时，相同的更新命令可以工作。
docker run -it ubuntu bash
执行apt-get update命令，显示成功。输出为:

apt-get update命令在主机和docker容器上都可以正常工作。我不知道善良的群集舱有什么问题。
替换Google公共DNS服务在机器上使用的名称服务器(DNS)。
sudo rm -f /etc/resolv.conf
sudo su
echo "nameserver 8.8.8.8" > /etc/resolv.conf
通过运行sudo vim /etc/default/docker更新默认的docker DNS并取消以下行
DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"
然后用sudo service docker restart重新启动docker
