 Garbage collection is a collective term for the various mechanisms Kubernetes uses to clean up
 cluster resources. 
-->
垃圾收集（Garbage Collection）是 Kubernetes 用于清理集群资源的各种机制的统称。

<!--more-->

<!-- 
Kubernetes uses garbage collection to clean up resources like
[unused containers and images](/docs/concepts/architecture/garbage-collection/#containers-images),
[failed Pods](/docs/concepts/workloads/pods/pod-lifecycle/#pod-garbage-collection),
[objects owned by the targeted resource](/docs/concepts/overview/working-with-objects/owners-dependents/),
[completed Jobs](/docs/concepts/workloads/controllers/ttlafterfinished/), and resources
that have expired or failed.
-->
Kubernetes 使用垃圾收集机制来清理资源，例如：
[未使用的容器和镜像](/zh-cn/docs/concepts/architecture/garbage-collection/#containers-images)、
[失败的 Pod](/zh-cn/docs/concepts/workloads/pods/pod-lifecycle/#pod-garbage-collection)、
[目标资源拥有的对象](/zh-cn/docs/concepts/overview/working-with-objects/owners-dependents/)、
[已完成的 Job](/zh-cn/docs/concepts/workloads/controllers/ttlafterfinished/)、
过期或出错的资源。
