问题

Ubuntu20.04搭建k8s coredns组件报错

因为/etc/resolve.conf中存在 nameserver 127.0.0.53回环地址造成循环引用

因为/etc/resolve.conf中存在 nameserver 127.0.0.53回环地址造成循环引用

原因

ubuntu17.0之后特有，systemd-resolvd服务会一直覆盖

解决办法

sudo apt install unbound
sudo systemctl stop systemd-resolved
sudo systemctl disable systemd-resolved
sudo rm -rf /etc/resolv.conf
# 删除后重新创建resolv.conf
sudo touch /etc/resolv.conf
