Atomic Host Is Being Sunset

The Atomic Host platform is being replaced by CoreOS. The Fedora project is no longer producing new versions of Atomic Host, but still provides updates for the Fedora 29 version of Atomic Host. The CentOS project continues to rebuild the RHEL 7 based versions of Atomic Host, but there is no plan for a RHEL 8 or CentOS 8 version of Atomic Host.

Users of Atomic Host are encouraged to join the CoreOS community on the IRC channel #fedora-coreos or on the discussion board.

The documentation contained below and throughout this site has been retained for historical purposes, but can no longer be guaranteed to be accurate.

Get Started with Atomic

Download an Atomic Host image

Atomic Host images are provided by the Fedora and the CentOS Projects.

The CentOS Atomic SIG offers a rebuild of Red Hat Enterprise Linux Atomic Host, considered a stable target. The Fedora Cloud SIG offers a new Fedora product Atomic Cloud Image.

The "QCOW2" image works on Linux KVM virtualization, for example it runs on RDO (OpenStack), oVirt, virt-manager and the "Boxes" virtual machine application available in Fedora and CentOS 7.

Both the Fedora and CentOS Atomic Host images are also available in Vagrant format, for use with the VirtualBox and libvirt/KVM providers, as well as in AMI format for running in EC2, and as ISO images for bare-metal installations.

Set Up the Virtual Machine

Please follow the Quick Start Guide to create a new virtual machine with Atomic and set up more disk space for your containers. This guide will set up a single host capable of running Docker containers.
