Introduction In Part 0 of this series we helped get a Fedora 26 Atomic Host system set up for the rest of this lab. In this section we will cover the following topics from the outline: Getting Familiar With Atomic Host Viewing Changes To A Deployed System Getting Familiar Atomic Host is built on top of underlying technology known as OSTree and leveraged by an RPM aware higher level technology known as rpm-ostree.

Introduction While Atomic Host has been around since 2014 there are still a lot of people that aren’t as familiar with the technology. The Atomic team within Red Hat, along with numerous other upstream contributors, have brought the OSTree and RPM-OSTree technology a long way.
