## 检查安装结果
执行命令，查看 Kuboard 的安装结果
```sh
watch kubectl get pod -n kube-system -o wide
```
输出结果如下所示：
> * kuboard-8b8574658-q4lvf 的状态为 `Running`，表明 Kuboard 启动正常
> * metrics-server-bd9789dfc-dbwvg 的状态为 `Running`，表明 metrics-server 启动正常。（ kuboard 以及 kubectl 依赖该组件以显示 top nodes、top pods 信息。

* ImagePullBackoff / Pending
* 如果 `kubectl get pod -n kube-system -o wide` 的输出结果中出现 ImagePullBackoff 或者长时间处于 Pending 的情况，请参考 [查看镜像抓取进度](/learning/faq/image-pull-backoff.html)
* ContainerCreating
* 如果 `kubectl get pod -n kube-system -o wide` 的输出结果中某个 Pod 长期处于 ContainerCreating、PodInitializing 或 Init:0/3 的状态，可以尝试：
* 查看该 Pod 的状态，例如：
``` sh
kubectl describe pod kuboard-8b8574658-q4lvf -n kube-system
```
如果输出结果中，最后一行显示的是 Pulling image，请耐心等待，或者参考 [查看镜像抓取进度](/learning/faq/image-pull-backoff.html)
```
Normal Pulling 44s kubelet, k8s02 Pulling image "eipwork/kuboard:latest"
```
* 将该 Pod 删除，系统会自动重建一个新的 Pod，例如：
``` sh
kubectl delete pod kuboard-8b8574658-q4lvf -n kube-system
```
