title: Kubernetes Cronjob runs more than once
body: <p>From kubernetes <a href="https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/" rel="nofollow noreferrer">docs</a> if I have a Cronjob that is executed each day at 00:00 say, and should only run once, the job template should have these fields:</p>
  
  <pre><code>.spec.concurrencyPolicy: Replace
  .spec.completions: 1
  .spec.parallelism: 1
  </code></pre>
  
  <p>However, the job is  being executed sometimes more than once, but now always, and this cases, the job is not failing either, and it successfully terminates.</p>
