Openssl self signed certificate creation fails if namespace name is long


I have given a long namespace name lets say more than 30 chars. In that case, OpenSSL fails because CN/SAN names go beyond defined limit of 64 chars for OpenSSL.

My deployment has a statefulset with 2 pods in it.

Certificate creation error:

How can I get around this? Any suggestions.

namespace: creatingabignamespacetobreakthefqdn
