To do so, set the .spec.backoffLimitPerIndex to specify the maximal number of pod failures per index.\n\nWhen the per-index backoff limit is exceeded for an index, Kubernetes considers the index as failed and adds it to the .status.failedIndexes field. The succeeded indexes, those with a successfully executed pods, are recorded in the .status.completedIndexes field, regardless of whether you set the backoffLimitPerIndex field.\n\nNote that a failing index does not interrupt execution of other indexes. Once all indexes finish for a Job where you specified a backoff limit per index, if at least one of those indexes did fail, the Job controller marks the overall Job as failed, by setting the Failed condition in the status. The Job gets marked as failed even if some, potentially nearly all, of the indexes were processed successfully.\n\nYou can additionally limit the maximal number of indexes marked failed by setting the .spec.maxFailedIndexes field. When the number of failed indexes exceeds the maxFailedIndexes field, the Job controller triggers termination of all remaining running Pods for that Job. Once all pods are terminated, the entire Job is marked failed by the Job controller, by setting the Failed condition in the Job status.\n\nHere is an example manifest for a Job that defines a backoffLimitPerIndex\n\nIn the example above, the Job controller allows for one restart for each of the indexes. When the total number of failed indexes exceeds 5, then the entire Job is terminated.\n\nOnce the job is finished, the Job status looks as follows\n\nBounded code example (external data; do not execute automatically):\n```sh\nkubectl get -o yaml job job-backoff-limit-per-index-example\n```\n\nBounded code example (external data; do not execute automatically):\n```yaml\n  status:\n    completedIndexes: 1,3,5,7,9\n    failedIndexes: 0,2,4,6,8\n    succeeded: 5          # 1 succeeded pod for each of 5 succeeded indexes\n    failed: 10            # 2 failed pods (1 retry) for each of 5 failed indexes\n    conditions:\n    - message: Job has failed indexes\n      reason: FailedIndexes\n      status: \"True\"\n      type: FailureTarget\n    - message: Job has failed indexes\n      reason: FailedIndexes\n      status: \"True\"\n      type: Failed\n``` …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
