How to find owner of cronjobs in Kubernetes and Kill it?
If a Kubernetes object is created by a controller, then its owner is listed in the per-object metadata. You already see this in your Pod output:
# kubectl get pod hello-27125624-kc9zw -oyamlmetadata: ownerReferences: - apiVersion: batch/v1 blockOwnerDeletion: true controller: true kind: Job name: hello-27125624 uid: 26beb7de-1c60-4854-a70f-54b6d066c22cThis same metadata format is used by every Kubernetes object. If there are no ownerReferences: then usually the object was directly created by a user (maybe via a tool like Helm or Kustomize).
If you similarly kubectl get job hello-27125624 -o yaml you will probably see a similar ownerReferences: block with apiVersion: batch/v1, kind: CronJob, and a specific name:. That object is probably user-managed and that's the object to delete.
