Overview

A Kubernetes Job is a workload resource that can be used to start and manage Pods to successful completion. A Pod is considered completed, and thus its execution counted against the completion counter only if finishes successfully. This counter can be configured with .spec.completions.

Clean up Finished Jobs Automatically

https://kubernetes.io/docs/concepts/workloads/controllers/job/#clean-up-finished-jobs-automatically

Jobs that have finished, either "Complete" or "Failed" can be automatically be deleted by using the TTL mechanism provided by the [TTL Controller ]. Set the .spec.ttlSecondsAfterFinished field in the job manifest. If the field is set to 0, the Job will be eligible to be automatically deleted immediately after it finishes.
