Today we’re releasing a significant update to the CentOS Atomic Host (version 7.20150908), a lean operating system designed to run Docker containers, built from standard CentOS 7 RPMs, and tracking the component versions included in Red Hat Enterprise Linux Atomic Host.
CentOS Atomic Host is available as a VirtualBox or libvirt-formatted Vagrant box, as an installable ISO image, as a qcow2 image, or as an Amazon Machine Image. These images are available for download at cloud.centos.org. The backing ostree repo is published to mirror.centos.org.
