参考：https://stackoverflow.com/questions/52645473/coredns-fails-to-run-in-kubernetes-cluster

1. open and edit the configmap of coredns.

   kubectl edit cm coredns -n kube-system

2. "replacing proxy . /etc/resolv.conf with the ip address of your upstream DNS, for example proxy . 8.8.8.8." According to the link in the output of the coredns log (at the end of the page)

3. save and exit.

4. kubectl get pods -n kube-system -oname |grep coredns |xargs kubectl delete -n kube-system

The reason of the problem is explained in the link. You can find this link in the output of this cmd

kubectl logs coredns-7d9cd4f75b-cpwxp -n kube-system
