1.查看pod信息
# 查看pod 報錯信息
kubectl get pods
發現pod的ip沒有 生成，也沒有分配到某個node節點
# 查看pod詳細時間
kubectl describe pods
發現pod事件為空
2.查看集群信息
kubectl get nodes
發現集群狀態正常
kubectl cluster-info
Kubernetes master is running at https://xx.xx.55.113
KubeDNS is running at https://xx.xx.55.113:6443/api
3. 查看kubelet日志發現
journalctl -xefu kubelet

4.清理docker占用的磁盤空間
#可以用於清理磁盤，刪除關閉的容器、無用的數據卷和網絡
docker system prune -a
5.之后再次部署，發現pod能正常啟動。
