Second edition of my Certified OpenStack Administrator study guide — pre-order from Apress for the Yoga COA exam.

Updated EX280 OpenShift Administration certification to OCP 4.2, five years after the original OpenShift 2.1 exam.

I have created diagram which shows how Director deployed services in RHOSP 10. That is something like summary for “UNDERSTANDING RED HAT OPENSTACK PLATFORM HIGH AVAILABILITY ” guide. If you learning RHOSP it would be useful.

I have received the results for EX220 Red Hat Certified Specialist in Hybrid Cloud Management today. Now I have Red Hat Certified Architect Level X.

This blog post describes the way to prepare a small lab in virtual environment intended for TripleO (Director) OpenStack deployment tool learning. This is a quick instruction. For deep understanding and command exploration use documentation . 

I used my home laptop with 16 Gb of memory and CentOS 7.3 on the top of it for the lab environment hardware and RHEL 7.3 and RHOPS 10 for virtual machines, but these instructions should be applicable for RDO OpenStack distribution with minor changes.
