Kubernetes pod部署错误FailedSync | 同步pod时出错

Question

环境:Windows 10台式机上的Vbox两个ubuntu虚拟机,一个虚拟机是主服务器,另一个是k8s(1.7)工作服务器.

在获取节点时,我可以看到两个节点"准备就绪".但是即使部署了一个非常简单的nginx pod,我从pod描述了"norm | SandboxChanged | Pod沙箱改变了它的错误消息 ,它将被杀死并重新创建." 和" 警告| FailedSync |错误同步窗格 ".

但是,如果我直接在worker上运行docker容器,则容器可以启动并运行.有人建议我可以检查什么？

k8s-master@k8smaster-VirtualBox:~$ **kubectl get pods** NAME
