Fedora CoreOS Frequently Asked Questions
What is Fedora CoreOS?
Fedora CoreOS is an automatically updating, minimal, monolithic, container-focused operating system, designed for clusters but also operable standalone, optimized for Kubernetes but also great without it. It aims to combine the best of both CoreOS Container Linux and Fedora Atomic Host, integrating technology like Ignition from Container Linux with rpm-ostree and SELinux hardening from Project Atomic. Its goal is to provide the best container host to run containerized workloads securely and at scale.

How does Fedora CoreOS relate to Red Hat CoreOS?
Fedora CoreOS is a freely available, community distribution that is the upstream basis for Red Hat CoreOS. While Fedora CoreOS embraces a variety of containerized use cases, Red Hat CoreOS provides a focused OS for OpenShift, released and life-cycled in tandem with the platform.

Does Fedora CoreOS replace Fedora Atomic Host? What happens to Fedora Atomic Host and CentOS Atomic Host?
Fedora CoreOS is the official successor to Fedora Atomic Host. The last Fedora Atomic Host release was version 29, which has now reached end-of-life.
CentOS Atomic Host will continue producing downstream rebuilds of RHEL Atomic Host and will align with the end-of-life. The Fedora CoreOS project will be the consolidation point for the community distributions. Users are encouraged to move there in the future.

What happens to Project Atomic?
Project Atomic is an umbrella project consisting of two flavors of Atomic Host (Fedora and CentOS) as well as various other container-related projects. Project Atomic as a project name will be sunset by the end of 2018 with a stronger individual focus on its successful projects such as Buildah and Cockpit. This merges the community side of the operating system more effectively with Fedora and allows for a clearer communication for other community-supported projects, specifically the well-adopted https://twitter.com/hashtag/nobigfatdaemons?src=hash[#nobigfatdaemons] approach of https://github.com/projectatomic/buildah[Buildah] and the versatile GUI server manager https://cockpit-project.org/[Cockpit].
