CentOS 8 job parenting strategy

As a general rule, the CentOS 7 master job has become something of a base job the contains most of the settings and RHEL and branch jobs parent off that. Since CentOS 7 master will become obsolete, we need to rework the parenting strategy.

General strategy

Option 1:

  • Move CentOS 8 master jobs to contain the majority of settings
  • Create CentOS 7 master jobs that parent off the CentOS 8 jobs so we don't break the current branch job parenting.
    • [chandankumar] Do we also need to change the parenting of RHEL-8 since it inherits from CentOS 7?
      Option 2:
  • Create separate parents and duplicate from
    https://github.com/openstack/tripleo-ci/blob/master/zuul.d/base.yaml
    Options 3:
  • Parent CentOS 8 off RHEL 8
