我按照kubernetes网站的说法进行了所有配置.(http://kubernetes.io/docs/getting-started-guides/centos/centos_manual_config/)

kubernetes-client-1.1.0-0.4.git2bfa9a1.el7.x86_64
    kubernetes-1.1.0-0.4.git2bfa9a1.el7.x86_64

    [root@xt3 kubernetes]# rpm -qa | grep etcd
    etcd-2.0.9-1.el7.x86_64

我期待着回答答案.请联系我.非常感谢.

解决方法

运行以下命令应该使它工作,因为kubelet可能卡在崩溃循环中：

sudo systemctl stop kubelet
sudo rm -rf /var/lib/kubelet/pods/*
sudo systemctl start kubelet
