One way to do this is to extract the yaml definition for a previous run of the job and create a pod definition replacing the command with an endless sleep.</p> <pre><code>kubectl get pod {previous-job-pod} -o yaml &gt; pod.yaml </code></pre> <p>Then edit the pod.yaml, removing the <code>status</code> block and the additional metadata referring to the previous job so the metadata only contains name and namespace</p>
