会运行容器化应用程序。每个集群至少有一个工作节点。

<!-- 
The worker node(s) host the {{< glossary_tooltip text="Pods" term_id="pod" >}} that are
the components of the application workload. The
{{< glossary_tooltip text="control plane" term_id="control-plane" >}} manages the worker
nodes and the Pods in the cluster. In production environments, the control plane usually
runs across multiple computers and a cluster usually runs multiple nodes, providing
fault-tolerance and high availability.

工作节点会托管 {{< glossary_tooltip text="Pod" term_id="pod" >}} 
，而 Pod 就是作为应用负载的组件。
{{< glossary_tooltip text="控制平面" term_id="control-plane" >}}管理集群中的工作节点和 Pod。
在生产环境中，控制平面通常跨多台计算机运行，
一个集群通常运行多个节点，提供容错性和高可用性。
