kubectl apply -f https://github.com/flannel-io/flannel/blob/629cd70d816e56853aac967f92ed3dade7275baf/Documentation/kube-flannel.yml

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
老师，打扰，部署master节点后报了这个错误，上面那个地址，浏览器都打不开，https://github.com/，https://raw.githubusercontent.com/，访问不通。

[root@master ~]# kubectl get pod -n kube-system

然后想执行kubectl apply -f kubeblog/docs/Chapter4/flannel.yaml试下。
报了这个错误
