Custom listener scripts and Cloud Native Unica container OS upgrade

Unica container OS upgrade from CentOS 8 to RHEL Universal Base Image (UBI) v8.5 may cause listener pod custom scripts to fail (applies to Cloud Native Unica versions 12.1.2 / 12.1.3).


  1. Modify custom scripts as per RHEL UBI OS. Example: Database Client Installation Script on listener pod.
  2. Centos8 OS was updated to RHEL UBI 8.5 because of CentOS 8 end of life.
  3. Also, RHEL UBI containers are less vulnerable to security threats because of the frequent fixing and release cycle.
