安装完成后可以查看下状态：
[root@master ~]# kubectl get nodes NAME STATUS AGE master Ready,master 6m minion01 Ready 2m minion02 Ready 2m 7 安装Calico网络网络组件选择很多，可以根据自己的需要选择calico、weave、flannel，calico性能最好，weave和flannel差不多。Addons中有配置好的yaml，部署环境使用的阿里云的VPC，官方提供的flannel.yaml创建的flannel网络有问题，所以本文中尝试calico网络，。
kubectl apply -f 0/getting-started/kubernetes/installation/hosted/kubeadm/calico.yaml如果使用了外部etcd，去掉其中以下内容，并修改etcd_endpoints: [ETCD_ENDPOINTS]：
