 ## 介绍
 
-端点切片为 Kubernetes 端点提供了可伸缩和可扩展的替代方案。它们建立在端点提供的功能基础之上，并以可伸缩的方式进行扩展。当服务具有大量（>100）网络端点，
-它们将被分成多个较小的端点切片资源，而不是单个大型端点资源。

-As an alpha feature, Endpoint Slices are not enabled by default in Kubernetes.
-Enabling Endpoint Slices requires as many as 3 changes to Kubernetes cluster
-configuration.
-
-To enable the Discovery API group that includes Endpoint Slices, use the runtime
- config flag (`--runtime-config=discovery.k8s.io/v1alpha1=true`).
-
-The logic responsible for watching services, pods, and nodes and creating or
-updating associated Endpoint Slices lives within the EndpointSlice controller.
-This is disabled by default but can be enabled with the controllers flag on
-kube-controller-manager (`--controllers=endpointslice`).
-
-For Kubernetes components like kube-proxy to actually start using Endpoint
-Slices, the EndpointSlice feature gate will need to be enabled
-(`--feature-gates=EndpointSlice=true`).
+EndpointSlice functionality in Kubernetes is made up of several different
+components, most are enabled by default:

+Kubernetes 中的 EndpointSlice 功能包含若干不同组件。它们中的大部分都是
+默认被启用的：
 
-作为 Alpha 功能，默认情况下，Kubernetes 中未启用端点切片。启用端点切片需要对 Kubernetes 集群进行多达 3 项配置修改。
-
-要启用包括端点切片的 Discovery API 组，请使用运行时配置标志（`--runtime-config=discovery.k8s.io/v1alpha1=true`）。
-
-该逻辑负责监视服务，pod 和节点以及创建或更新与之关联，在端点切片控制器内的端点切片。
-默认情况下，此功能处于禁用状态，但可以通过启用在 kube-controller-manager 控制器的标志（`--controllers=endpointslice`）来开启。

+## 使用 EndpointSlice
 
-## 使用端点切片
+在集群中完全启用 EndpointSlice 的情况下，你应该看到对应于每个
+Endpoints 资源的 EndpointSlice 资源。除了支持现有的 Endpoints 功能外，
+EndpointSlice 还引入了拓扑结构等新的信息。它们将使集群中网络端点具有更强的
+可伸缩性和可扩展性。
