title: How to access key in a map returned by kubectl
body: <p>I want to access limits.memory variable returned by get command in k8s</p>
  
  <pre><code>kubectl get resourcequota default -n 103000-p4-dev -o custom-columns=USED:.status.used
  USED
  map[limits.memory:0 requests.cpu:0 requests.memory:0]
  </code></pre>
  
  <p>I tried many ways but couldn't succeed</p>
  
  <pre><code>[root@iaasn00126847 ~]# k get resourcequota default -n 103000-p4-dev -o custom-columns=USED:.status.used.limits.memory
  </code></pre>
  
  <p>returns nothing</p>
  
  <p>Is there a delimiter to fetch the same</p>
