How To Install rpm-ostree on CentOS 8
Introduction
In this tutorial we learn how to install rpm-ostree on CentOS 8.
What is rpm-ostree
rpm-ostree is a hybrid image/package system. It supports “composing” packages on a build server into an OSTree repository, which can then be replicated by client systems with atomic upgrades. Additionally, unlike many “pure” image systems, with rpm-ostree each client system can layer on additional packages, providing a “best of both worlds” approach.
We can use yum or dnf to install rpm-ostree on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install rpm-ostree.
