<p>In Kubernetes docs <a href="https://kubernetes.io/docs/concepts/workloads/pods/#working-with-pods" rel="nofollow noreferrer">here</a> I can see that the pod name follows a valid &quot;DNS subdomain name&quot; which means 253 char limit but here in this article <a href="https://pauldally.medium.com/why-you-try-to-keep-your-deployment-names-to-47-characters-or-less-1f93a848d34c" rel="nofollow noreferrer">here</a> they have mentioned that you should try to keep deployment name below 47 char as pod name limit to 63 char. Also, I tried creating a pod with a deployment name of more than 63 chars but the pod name got truncated to 63 chars.<br />
So, what is the correct char limit for the pod name?</p>

<p>A domain name is a series of labels with max length of 255; where each label with max length of 63 bytes. The K8s document is referring to the label. See <a href="https://www.freesoft.org/CIE/RFC/1035/9.htm" rel="nofollow noreferrer">here</a> for the RFC standard.</p>
