<p>I have a file named config.txt, which i used to create configmap <strong>myconfig</strong> inside minikube cluster.</p>
<p>However, when I use <strong>myconfig</strong> in a Pod, the name of the file config.txt also shows up as part of the ENV.</p>
<p>How can I correct it?</p>
<pre class="lang-sh prettyprint-override"><code>&gt; cat config.txt
var3=val3
var4=val4

&gt; kubectl create cm myconfig --from-file=config.txt
configmap/myconfig created

&gt; kubectl describe cm myconfig
Name:         myconfig

<p>Pod EVN inspection, notice the line <strong>config.txt=var3=val3</strong>
expected it to be just <strong>var3=val3</strong></p>

<p>Create configmap like this will do the job:</p>
<pre><code>kubectl create cm myconfig --from-env-file=config.txt
