验证集群

[root@cx-- ~]# kubectl cluster-info
Kubernetes master is running at https://172.16.2.17/k8s/clusters/c-pqtft
KubeDNS is running at https://172.16.2.17/k8s/clusters/c-pqtft/api/v1/namespaces/kube-system/services/kube-dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
