Note that when the Job is deleted, its lifecycle guarantees, such as finalizers, will be honored.\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiVersion: batch/v1\nkind: Job\nmetadata:\n  name: pi-with-ttl\nspec:\n  ttlSecondsAfterFinished: 100\n  template:\n    spec:\n      containers:\n      - name: pi\n        image: perl:5.34.0\n        command: [\"perl\", \"-Mbignum=bpi\", \"-wle\", \"print bpi(2000)\"]\n      restartPolicy: Never\n```\n\nThe Job pi-with-ttl will be eligible to be automatically deleted, 100 seconds after it finishes.\n\nIf the field is set to 0, the Job will be eligible to be automatically deleted immediately after it finishes. If the field is unset, this Job won't be cleaned up by the TTL controller after it finishes.\n\nIt is recommended to set ttlSecondsAfterFinished field because unmanaged jobs (Jobs that you created directly, and not indirectly through other workload APIs such as CronJob) have a default deletion policy of orphanDependents causing Pods created by an unmanaged Job to be left around after that Job is fully deleted. Even though the eventually garbage collects the Pods from a deleted Job after they either fail or complete, sometimes those lingering pods may cause cluster performance degradation or in worst case cause the cluster to go offline due to this degradation.\n\nYou can use LimitRanges and ResourceQuotas to place a cap on the amount of resources that a particular namespace can consume.\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
