title: Kubectl update configMap
body: <p>I am using the following command to create a configMap.</p>
  
  <pre><code>kubectl create configmap test --from-file=./application.properties --from-file=./mongo.properties --from-file=./logback.xml 
  </code></pre>
  
  <p>Now, I have modified a value for a key from mongo.properties which i need to update in kubernetes.</p>
  
  <p><strong>Option1 :-</strong></p>
  
  <pre><code>kubectl edit test
  </code></pre>
  
  <p>Here, it opens the entire file. But, I want to just update mongo.properties and hence want to see only the mongo.properties.  Is there any other way?</p>
  
  <blockquote>
    <p>Note :- I dont want to have mongo.properties in a separate configMap.</p>
  </blockquote>
  
  <p>Thanks</p>
