This stops new jobs from being created. However, running jobs won't be stopped, and no jobs or their pods will
be deleted. To clean up those jobs and pods, you need to list all jobs created by the cron job, and delete them all:
```shell
$ kubectl get jobs
NAME DESIRED SUCCESSFUL AGE
hello-1201907962 1 1 11m
hello-1202039034 1 1 8m
...
$ kubectl delete jobs hello-1201907962 hello-1202039034 ...
job "hello-1201907962" deleted
job "hello-1202039034" deleted
...
```
Once the jobs are deleted, the pods created by them are deleted as well. Note that all jobs created by cron
job "hello" will be prefixed "hello-". You can delete them at once with `kubectl delete jobs --all`, if you want to
delete all jobs in the current namespace (not just the ones created by "hello").
This stops new jobs from being created and removes all the jobs and pods created by this cronjob.
You can read more about it in [garbage collection section](/docs/concepts/cluster-administration/kubelet-garbage-collection/).

The `.spec.successfulJobsHistoryLimit` and `.spec.failedJobsHistoryLimit` fields are optional.
These fields specify how many completed and failed jobs should be kept. By default, they are
set to 3 and 1 accordingly. Setting a limit to `0` corresponds to keeping none of the corresponding
set to 3 and 1 respectively. Setting a limit to `0` corresponds to keeping none of the corresponding
kind of jobs after they finish.
