kubernetes coredns无法解析baremetal配置中的kubernetes.default

我已经安装了Kubernetes 1.13和busybox 1.28。软件无法解析kubernetes。默认值

我尝试了调试coredns问题的步骤 . 在这些步骤中，只有一件事不起作用

当我运行此命令时：

kubectl exec -ti busybox -- nslookup kubernetes.default 

我得到以下回应：

nslookup: can't resolve 'kubernetes.default'

My configuration
Distributor ID: Ubuntu

那CNI呢？您是否使用法兰绒或其他材料，能否描述CNI吊舱并检查输出
