[root@xt3 kubernetes]# rpm -qa | grep kuber kubernetes-node-1.1.0-0.4.git2bfa9a1.el7.x86_64
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 kubernetes-master-1.1.0-0.4.git2bfa9a1.el7.x86_64 [root@xt3 kubernetes]# rpm -qa | grep etcd etcd-2.0.9-1.el7.x86_64
