### 查看該圖，您可以發現以下組件，我使用圖標來表示服務和標籤：

* Pods
* Containers
* Label(s) ([![label](http://omerio.com/wp-content/uploads/2015/12/label.png)](http://omerio.com/wp-content/uploads/2015/12/label.png))
* Replication Controllers
* Service ([![service](http://omerio.com/wp-content/uploads/2015/12/service.png)](http://omerio.com/wp-content/uploads/2015/12/service.png))
* Nodes
* Kubernetes Master

### Cluster：由 Master 來管理底下的 Node。

### Pod：對 Container 再一次封裝，之後如果要 Scale，就會自動新增刪減 Pod是最小單位。

### Service：Pod 運行後需要透過定義 Service 才能讓外部的使用者訪問。
