12 modules, each with 12 chapters (144 chapters total), text-based, plus downloadable templates and a hand-built implementation playbook delivered alongside course access.
Version upgrades should strengthen your system, not introduce risk or downtime.

The situation this course is for

Even small CNF version jumps can cascade into configuration drift, TLS store misalignment, or discovery failures if not managed systematically. The pressure to deliver fast while maintaining compliance and stability is real.

Who this is for

A platform engineer or DevOps lead responsible for F5 CNF stability on OpenShift, focused on clean, auditable upgrades without service disruption.

Who this is not for

Developers focused on application code rather than infrastructure versioning, or teams not using F5 CNFs on OpenShift.

What you walk away with

  • Execute zero-downtime CNF version upgrades with confidence
  • Align configuration patterns across environments using proven upgrade checklists
  • Prevent TLS and service discovery misconfigurations during version transitions
  • Document upgrade decisions for audit and compliance readiness
  • Reduce mean time to recovery after upgrade-related incidents

If nothing changes
Without a structured approach, CNF upgrades risk configuration errors, TLS failures, and service discovery outages, especially in regulated or high-availability environments.

How this compares to the alternatives

Unlike generic Kubernetes courses, this focuses exclusively on F5 CNF upgrade patterns, giving you precise, actionable steps instead of broad theory.
