<p>Some kubernetes resources have a length limit of 63 characters (presumably because they need to be valid DNS names). Which are they?</p>

<p>Those are <strong>at least</strong>:</p>

<ul>
<li>Pod names</li>
<li>Service names</li>
<li>The name part of a label key</li>
</ul>

<pre><code>    labels:
      example.com/environment: production                       &lt;-- the string "environment"
</code></pre>

<ul>
<li>The label value</li>
</ul>

<pre><code>    labels:
      example.com/environment: production                       &lt;-- the string "production"
</code></pre>

<ul>
<li>The name part of an annotation key</li>
</ul>

<pre><code>    annotations:
      example.com/image-registry: "https://hub.docker.com/"     &lt;-- the string "image-registry"
</code></pre>

<ul>
<li>CronJob names (including 11 automatically appended characters)</li>
</ul>
