title: How can you scale out a Job that is already created?
body: <p>I have a Kubernetes Job that has, for instance, parallelism set to 4. When this job is created, I might want to scale this out to, say, 8. But it seems like <code>edit</code>ing the Job and setting parallelism to 8 doesn't actually create more pods in the Job.</p>
  <p>Am I missing something? Or is there no way to scale out a Job?</p>
