在 Kubernetes 中,`Endpoint Slice`包含对一组网络端点的引用。指定选择器后,EndpointSlice 控制器会自动为 Kubernetes 服务创建 Endpoint Slices。这些 Endpoint Slices 将包含对与服务选择器匹配的所有 Pod 的引用。Endpoint Slices 通过唯一的服务和端口组合将网络端点组织在一起。 在 Kubernetes 中,`EndpointSlice` 包含对一组网络端点的引用。指定选择器后,EndpointSlice 控制器会自动为 Kubernetes 服务创建 EndpointSlice。这些 EndpointSlice 将包含对与服务选择器匹配的所有 Pod 的引用。EndpointSlice 通过唯一的服务和端口组合将网络端点组织在一起。

Endpoints API 提供了一种简单明了的方法在 Kubernetes 中跟踪网络端点。不幸的是,随着 Kubernetes 集群与服务的增长,该 API 的局限性变得更加明显。最值得注意的是,这包含了扩展到更多网络端点的挑战。 Endpoints API 提供了一种简单明了的方法在 Kubernetes 中跟踪网络端点。不幸的是,随着 Kubernetes 集群与服务的增长,该 API 的局限性变得更加明显。最值得注意的是,这包含了扩展到更多网络端点的挑战。
