Kubernetes Job with single Pod vs single Pod with restart policy OnFailure
<p>What are the benefits of a Job with single Pod over just a single Pod with restart policy OnFailure to reliably execute once in kubernetes?</p>

<p>As discussed in <a href="https://github.com/kubernetes/kubernetes/issues/20255" rel="noreferrer">Job being constanly recreated despite RestartPolicy: Never</a>, in case of a Job a new Pod will be created endlessly in case container returned non-zero status. The same applies to a single OnFailure Pod, only this time no new pods are created which is even cleaner. </p>

<p>What are the cons and pros of either approach? Can Pod restart parameters, such as restart delay, or number of retry attempts can be controlled in either case?</p>
