Kubernetes CronJobs (previously ScheduledJobs) GA since Kubernetes 1.21 (April 2021) and Beta since Kubernetes 1.8.
CronJobs are meant for performing regular scheduled actions such as backups, report generation, and so on. Each of those tasks should be configured to recur indefinitely (for example: once a day / week / month); you can define the point in time within that interval when the job should start.
