title: When will a kube object have more than one ownerReferences
body: <p>When a kubernetes object has parent objects, it is mentioned under "ownerReferences".  For example when i printed a pod spec in yaml format, i see ownerReferences mentioned as follows:</p>
  
  <pre><code>  ownerReferences:
    - apiVersion: apps/v1
      blockOwnerDeletion: true
      controller: true
      kind: StatefulSet
      name: statefuleset-name
      uid: &lt;uuid&gt;
  ....
  </code></pre>
  
  <p>I see that ownerReferences is a list.  Does anyone know when the ownerReferences will have more than one entries.  I am not able to imagine a object having more than one owner.</p>
