In this blog post, we will share some recommendations and good practices followed by the Telco Partner CI team for partners and internal Red Hat teams working with these partners to prepare OpenShift workloads for certification. The suggested process or workflow can be easily replicated in the collaboration between partners and Red Hat teams. We will show you, as part of the implementation of this workflow, how you can automate the report and analysis of preflight and CNF Certification tests launched with Distributed-CI (DCI) using spreadsheets to gather all the results and to check the evolution of the tests results. These tools would be eventually useful for Red Hat teams to follow up the certification process with the partner and also to justify exception requests based on what is observed in the support tools.
