<!--
This feature gate controls the point at which a default value for
`.spec.containers[*].ports[*].hostPort`
is assigned, for Pods using `hostNetwork: true`. The default since Kubernetes v1.28 is to only set a default
value in Pods.

Enabling this means a default will be assigned even to the `.spec` of an embedded
[PodTemplate](/docs/concepts/workloads/pods/#pod-templates) (for example, in a Deployment),
which is the way that older releases of Kubernetes worked.
You should migrate your code so that it does not rely on the legacy behavior.
-->
此特性门控将控制何时为使用 `hostNetwork: true` 的 Pod 设置
`.spec.containers[*].ports[*].hostPort` 默认值。

启用此特性意味着默认值甚至会分配给嵌入式
[PodTemplate](/zh-cn/docs/concepts/workloads/pods/#pod-templates)（例如，Deployment）
的 `.spec`，这是 Kubernetes 旧版本的工作方式。
你应该迁移你的代码，使其不再依赖于原先的行为。
