title: How to Merge the contents of ConfigMaps in Kubernetes
body: <p>We have our app specific properties specified in the below files</p>
  
  <pre><code>application.properties
  application-dev.properties
  application-qa.properties
  </code></pre>
  
  <p>While creating a configmap in kubernetes, I wanted to merge the contents into one single file. Is it possible to merge the contents?</p>
  
  <p>I know we can achieve through kustomize. However we are using Helm Charts and we are not using kustomize.</p>
