+**Kubernetes 是一个生产级别的开源平台，
+可编排在计算机集群内和跨计算机集群的应用容器的部署（调度）和执行。**

+<!--
+**Kubernetes coordinates a highly available cluster of computers that are connected
+to work as a single unit.** The abstractions in Kubernetes allow you to deploy
+containerized applications to a cluster without tying them specifically to individual
+machines. To make use of this new model of deployment, applications need to be packaged
+in a way that decouples them from individual hosts: they need to be containerized.
+Containerized applications are more flexible and available than in past deployment models,
+where applications were installed directly onto specific machines as packages deeply
+integrated into the host. **Kubernetes automates the distribution and scheduling of
+application containers across a cluster in a more efficient way.** Kubernetes is an
+open-source platform and is production-ready.
+-->
+**Kubernetes 协调一个高可用计算机集群，每个计算机互相连接之后作为同一个工作单元运行。**
+Kubernetes 中的抽象允许你将容器化的应用部署到集群，而无需将它们绑定到某个特定的独立计算机。
+为了使用这种新的部署模型，需要以将应用与单个主机解耦的方式打包：它们需要被容器化。
+与过去的那种应用直接以包的方式深度与主机集成的部署模型相比，容器化应用更灵活、更可用。
+**Kubernetes 以更高效的方式跨集群自动分布和调度应用容器。**
+Kubernetes 是一个开源平台，并且可应用于生产环境。

+A Kubernetes cluster consists of two types of resources:
+
+* The **Control Plane** coordinates the cluster
+* **Nodes** are the workers that run applications
+-->
+一个 Kubernetes 集群包含两种类型的资源：
+
+* **控制面（Control Plane）** 调度整个集群
+* **节点（Nodes）** 负责运行应用

+
+<!--
+**A node is a VM or a physical computer that serves as a worker machine in a Kubernetes
+cluster.** Each node has a Kubelet, which is an agent for managing the node and
+communicating with the Kubernetes control plane. The node should also have tools for
+handling container operations, such as {{< glossary_tooltip text="containerd" term_id="containerd" >}}
+or {{< glossary_tooltip term_id="cri-o" >}}. A Kubernetes cluster that handles production
+traffic should have a minimum of three nodes because if one node goes down, both an
+[etcd](/docs/concepts/architecture/#etcd) member and a control plane instance are lost,
+and redundancy is compromised. You can mitigate this risk by adding more control plane nodes.
+-->
+**节点是一个虚拟机或者物理机，它在 Kubernetes 集群中充当工作机器的角色。**
+每个节点都有 Kubelet，它管理节点而且是节点与控制面通信的代理。
+节点还应该具有用于处理容器操作的工具，例如 {{< glossary_tooltip text="containerd" term_id="containerd" >}}
+或 {{< glossary_tooltip term_id="cri-o" >}}。
+处理生产级流量的 Kubernetes 集群至少应具有三个节点，因为如果只有一个节点，出现故障时其对应的
+[etcd](/zh-cn/docs/concepts/architecture/#etcd) 成员和控制面实例都会丢失，
+并且冗余会受到影响。你可以通过添加更多控制面节点来降低这种风险。
+
+<!--
+When you deploy applications on Kubernetes, you tell the control plane to start
+the application containers. The control plane schedules the containers to run on
+the cluster's nodes. **Node-level components, such as the kubelet, communicate
+with the control plane using the [Kubernetes API](/docs/concepts/overview/kubernetes-api/)**,
+which the control plane exposes. End users can also use the Kubernetes API directly
+to interact with the cluster.
+-->
+在 Kubernetes 上部署应用时，你告诉控制面启动应用容器。
+控制面就编排容器在集群的节点上运行。
+**节点使用控制面所公布的 [Kubernetes API](/zh-cn/docs/concepts/overview/kubernetes-api/)**
+与控制面通信。终端用户也可以使用 Kubernetes API 与集群交互。
+
+<!--
+A Kubernetes cluster can be deployed on either physical or virtual machines. To
+get started with Kubernetes development, you can use Minikube. Minikube is a lightweight
+Kubernetes implementation that creates a VM on your local machine and deploys a
+simple cluster containing only one node. Minikube is available for Linux, macOS,
+and Windows systems. The Minikube CLI provides basic bootstrapping operations for
+working with your cluster, including start, stop, status, and delete.
+-->
+Kubernetes 既可以部署在物理机上也可以部署在虚拟机上。你可以使用 Minikube 开始部署 Kubernetes 集群。
+Minikube 是一种轻量级的 Kubernetes 实现，可在本地计算机上创建 VM 并部署仅包含一个节点的简单集群。
+Minikube 可用于 Linux、macOS 和 Windows 系统。Minikube CLI 提供了用于引导集群工作的多种操作，
+包括启动、停止、查看状态和删除。
