将运行在一个或一组 {{< glossary_tooltip text="Pod" term_id="pod" >}} 上的网络应用程序公开为网络服务的方法。

<!--
|
||
The set of Pods targeted by a Service is (usually) determined by a
|
||
{{< glossary_tooltip text="selector" term_id="selector" >}}. If more Pods are added or removed,
|
||
the set of Pods matching the selector will change. The Service makes sure that network traffic
|
||
can be directed to the current set of Pods for the workload.
|
||
-->
|
||
服务所针对的 Pod 集（通常）由{{< glossary_tooltip text="选择算符" term_id="selector" >}}确定。
|
||
如果有 Pod 被添加或被删除，则与选择算符匹配的 Pod 集合将发生变化。
|
||
服务确保可以将网络流量定向到该工作负载的当前 Pod 集合。

Kubernetes Services either use IP networking (IPv4, IPv6, or both), or reference an external name in
|
||
the Domain Name System (DNS).
|
||
|
||
The Service abstraction enables other mechanisms, such as Ingress and Gateway.

|
||
|
||
Kubernetes Service 要么使用 IP 网络（IPv4、IPv6 或两者），要么引用位于域名系统 (DNS) 中的外部名称。
|
||
|
||
Service 的抽象可以实现其他机制，如 Ingress 和 Gateway。
