flannel安装出现CrashLoopBackOff

Question

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
NAME                             READY   STATUS             RESTARTS   AGE

kube-scheduler-master            1/1     Running            3          22d

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

podsecuritypolicy.policy/psp.flannel.unprivileged configured
clusterrole.rbac.authorization.k8s.io/flannel unchanged
clusterrolebinding.rbac.authorization.k8s.io/flannel unchanged
serviceaccount/flannel unchanged

kubectl logs -f -n `(kubectl get pod -A | grep "kube-flannel-ds" | awk '{print $1" "$2}' | head -1 )`

看下flannel pod的日志
