+Kubernetes uses garbage collection to clean up resources like [unused containers and images](/docs/concepts/workloads/controllers/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.

+[失败的 Pod](/zh/docs/concepts/workloads/pods/pod-lifecycle/#pod-garbage-collection)、
+[目标资源拥有的对象](/zh/docs/concepts/overview/working-with-objects/owners-dependents/)、
+[已完成的 Job](/zh/docs/concepts/workloads/controllers/ttlafterfinished/)、
+过期或出错的资源。
