6 commands

Pro Tips

Set 'backoffLimit' on Jobs to control retry attempts. Set 'activeDeadlineSeconds' for timeout.

Use 'successfulJobsHistoryLimit' and 'failedJobsHistoryLimit' on CronJobs to manage old job retention.

Test CronJobs by creating a Job from them: 'kubectl create job test --from=cronjob/mycronjob'

Common Mistakes

CronJobs may create multiple Jobs if a previous run hasn't completed. Set 'concurrencyPolicy: Forbid' to prevent this.

Jobs don't clean up their pods by default. Set 'ttlSecondsAfterFinished' for automatic cleanup.
