This will need some investigation if you're not going to use kubectl apply. The command to run instead is:
kubectl edit cronjob job-cleanup
That launches the YAML spec in your editor - in the spec for the CronJob you'll find the field suspend. Just change the value from false to true, save the file and exit the editor.
Kubectl applies the change when the editor exits:
kubectl get cronjob
Now the CronJob is suspended, so the spec is still there but it won't create any more Jobs.
This one is straightforward but you tend to use kubectl create rarely and you might forget what it can do:
kubectl create job --help
Shows you the exact syntax you need. For this lab:
kubectl create job db-backup-job --from=cronjob/db-backup
kubectl get jobs -l app=db-backup
kubectl logs -l app=db-backup
Adding the lab label will help with cleanup:
kubectl label job db-backup-job kubernetes.courselabs.co=jobs
