[root@k8s-master dashboard]# kubectl describe pod kubernetes-dashboard-765c8bfdff-ddwvw -n kube-system  ####查看原因
发现里面的一个image地址写错了，解决办法如下：
[root@k8s-master dashboard]# kubectl delete -f dashboard-controller.yaml
deployment "kubernetes-dashboard" deleted
[root@k8s-master dashboard]# kubectl create -f dashboard-controller.yaml
deployment "kubernetes-dashboard" created
