title: Delete key from configmap in Kubernetes
body: <p>Is there a nice way to delete a specific key from a Kubernetes configmap, using kubectl?</p>
  
  <p>Right now I run: </p>
  
  <pre><code>$ kubectl edit configmap myconfigmap
  </code></pre>
  
  <p>and then I delete the entry but I would like a solution that can be run as a script.</p>
