k8s在创建dashboard的时候，提示镜像不无法下载，但实际本地已经有镜像了！

现象：1、在安装完k8s以后，加载ui面：kubectl create -f kubernetes-dashboard.yaml 2、查看容器状态：[root@k8s-master software]# kubectl get pods --namespace kube-systemNAME READY STATUS RESTARTS AGEkuberne...显示全部

现象：
1、在安装完k8s以后，加载ui面：
kubectl create -f kubernetes-dashboard.yaml
2、查看容器状态：
[root@k8s-master software]# kubectl get pods --namespace kube-system
NAME READY STATUS RESTARTS AGE
kubernetes-dashboard-3852341777-135gm 0/1 ContainerCreating 0 5m
3、检查报错信息：
[root@k8s-master software]# kubectl describe pod kubernetes-dashboard-3852341777-135gm --namespace kube-system

4、查看本地镜像（本地gcr.io/google_containers/pause-amd64已经有这个镜像了，镜像是从docker pull daocloud.io/daocloud/google_containers_pause-amd64:3.0下载的）：

[root@k8s-master ~]# docker images

    已经解决，在node节点主机上，修改kubelet.service启动参数，增加--pod-infra-container-image=registry.sinosafe.com.cn:5000/sinosafe/pause-amd64:3.0即可解决该问题
