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.
Currently, the CentOS Atomic Host includes these core component versions:
- kernel 3.10.0-229
- docker 1.7.1-108
- kubernetes 1.0.0-0.8.gitb2dafda
- etcd 2.0.13-2
- flannel 0.2.0-10
- cloud-init 0.7.5-10
- ostree 2015.6-4
- atomic 1.0-108
For more information, go check out the release announcement at the CentOS project blog. If you’re particularly impatient, vagrant offers the fastest route to getting up and running with the new image:
$ vagrant init centos/atomic-host && vagrant up
