title: Does a completed kubernetes pod still reserves the required resources?
body: <p>If I have a <code>CronJob</code> the has <code>requests.memory</code> of, let's say, <code>100Mi</code>, when the pod finishes and enter on <code>Completed</code> state, does it still "reserves" that amount of memory, or are the requested resources freed up?</p>
  
  <p>Both <a href="https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/" rel="noreferrer">Jobs docs</a> and <a href="https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/" rel="noreferrer">Pod Lifecycle docs</a> don't specify what happens after the pods in on <code>Completed</code> phase.</p>
