K8s CoreDNS

[charleswan]

I encountered an issue that shows the following. Does anyone know how to resolve it?

$ sudo kubeadm init --pod-network-cidr=192.168.0.0/16 --apiserver-advertise-address=172.31.89.68 --node-name master --image-repository k8s-gcr.m.daocloud.io

It's a coredns problem, its changed paths and tag styles you need to confirm the exact path, then retag
这是coredns 的问题 其不仅仅换过路径明还改过tag的风格 你需要确认准确的路径, 然后 retag
