title: Increase memory limit of a running pod
body: <p>I have a pod running in openshift 3.11, I wish to increase the pod memory limit from 2GB to 4GB. How to do it via Openshift Web Console or via OC command line?</p>
  <p>When I try to edit the yaml file in Openshift Web Console  I got the following exception</p>
  <blockquote>
  <p>Reason: Pod &quot;hjaha&quot; is invalid: spec: Forbidden: pod updates may not
  change fields other than <code>spec.containers[*].image</code>,
  <code>spec.initContainers[*].image</code>, <code>spec.activeDeadlineSeconds</code> or
  <code>spec.tolerations</code> (only additions to existing tolerations)...</p>
