title: What is the reverse of "kubectl apply"?
body: <p>I was playing around in minikube and installed the wrong version of istio.  I ran:</p>
  
  <pre><code>kubectl apply -f install/kubernetes/istio-demo-auth.yaml
  </code></pre>
  
  <p>instead of:</p>
  
  <pre><code>kubectl apply -f install/kubernetes/istio-demo.yaml
  </code></pre>
  
  <p>I figured I would just undo it and install the right one.</p>
  
  <p>But I cannot seem to find an <code>unapply</code> command.</p>
  
  <p><strong>How do I <em>undo</em> a "kubectl apply" command?</strong></p>
