Pod 水平自动扩缩器（Horizontal Pod Autoscaler）是一种 API 资源，它根据目标 CPU 利用率或自定义度量目标扩缩 {{< glossary_tooltip term_id="pod" >}} 副本的数量。

HPA is typically used with {{< glossary_tooltip text="ReplicationControllers" term_id="replication-controller" >}}, {{< glossary_tooltip text="Deployments" term_id="deployment" >}}, or {{< glossary_tooltip text="ReplicaSets" term_id="replica-set" >}}. It cannot be applied to objects that cannot be scaled, for example {{< glossary_tooltip text="DaemonSets" term_id="daemonset" >}}.
|
||
-->
|
||
HPA 通常用于 {{< glossary_tooltip text="ReplicationController" term_id="replication-controller" >}}
|
||
、{{< glossary_tooltip text="Deployment" term_id="deployment" >}}
|
||
或者 {{< glossary_tooltip text="ReplicaSet" term_id="replica-set" >}} 上。
|
||
HPA 不能用于不支持扩缩的对象，例如 {{< glossary_tooltip text="DaemonSets" term_id="daemonset" >}}。
