<p>Just ran the following command to create a new ConfigMap from a file:<br>
<code>kubernetes create configmap foo --from-file=foo</code></p>

<p>It gets created successfully.</p>

<p>Now when I run,<br>
<code>kubernetes get configmaps foo -o yaml</code></p>

<p>I see the following lines in the resulting output:  </p>

<pre><code>apiVersion: v1
data:
  foo: |+
    VAR1=value1
    VAR2=value2
</code></pre>

<p><strong>What does the plus sign in this line mean?</strong><br>
<code>foo: |+</code></p>

<p>It doesn't appear in any of my other ConfigMaps.</p>

<p><code>|+</code> is not kubernetes specific, it's part of yaml.</p>

<p>From <a href="http://lzone.de/cheat-sheet/YAML" rel="noreferrer">http://lzone.de/cheat-sheet/YAML</a>:</p>

<pre><code># + indicator (keep extra newlines after block)
content: |+
   Arbitrary free text with two newlines after


foo: ...
</code></pre>
