		Delete resources by filenames, stdin, resources and names, or by resources and label selector.

		JSON and YAML formats are accepted. Only one type of the arguments may be specified: filenames,
		resources and names, or resources and label selector.

		Some resources, such as pods, support graceful deletion. These resources define a default period
		before they are forcibly terminated (the grace period) but you may override that value with
		the --grace-period flag, or pass --now to set a grace-period of 1. Because these resources often
		represent entities in the cluster, deletion may not be acknowledged immediately. If the node
		hosting a pod is down or cannot reach the API server, termination may take significantly longer
		than the grace period. To force delete a resource, you must pass a grace period of 0 and specify
		the --force flag.

		IMPORTANT: Force deleting pods does not wait for confirmation that the pod's processes have been
		terminated, which can leave those processes running until the node detects the deletion and
		completes graceful deletion. If your processes use shared storage or talk to a remote API and
		depend on the name of the pod to identify themselves, force deleting those pods may result in
		multiple processes running on different machines using the same identification which may lead
		to data corruption or inconsistency. Only force delete pods when you are sure the pod is
		terminated, or if your application can tolerate multiple copies of the same pod running at once.
		Also, if you force delete pods the scheduler may place new pods on those nodes before the node
		has released those resources and causing those pods to be evicted immediately.

		Note that the delete command does NOT do resource version checks, so if someone submits an
		update to a resource right when you submit a delete, their update will be lost along with the
		rest of the resource.`))
