Subject: [CentOS-devel] Announcing a New CentOS Atomic Host Release
Date: Thu, 10 Sep 2015 17:15:18 -0400 (EDT)
From: Jason Brooks <jbrooks redhat com>
Reply-To: The CentOS developers mailing list. <centos-devel centos org>

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
http://cloud.centos.org/centos/7/atomic/images/. The backing ostree repo is
published to http://mirror.centos.org/centos/7/atomic/x86_64/repo.
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
Upgrading
---------
If you’re running the version of CentOS Atomic Host that shipped in June,
you can upgrade to the current image by running the following command:
$ sudo atomic host upgrade
If you’re currently run the older, test version of the CentOS Atomic Host,
or if you’re running any other atomic host (from any distro or release in
the past), you can rebase to this released CentOS Atomic Host by running
the following two commands :
$ sudo ostree remote add centos-atomic-host \
http://mirror.centos.org/centos/7/atomic/x86_64/repo
$ sudo rpm-ostree rebase \
centos-atomic-host:centos-atomic-host/7/x86_64/standard
Images

### Vagrant
CentOS-Atomic-Host-7-Vagrant-Libvirt.box (393 MB) and
CentOS-Atomic-Host-7-Vagrant-Virtualbox.box (404 MB) are Vagrant boxes for
Libvirt and Virtualbox providers.
The easiest way to consume these images is via the Atlas / Vagrant Cloud
setup (see https://atlas.hashicorp.com/centos/boxes/atomic-host). For
example, getting the VirtualBox instance up would involve running the
following two commands on a machine with vagrant installed:
$ vagrant init centos/atomic-host && vagrant up --provider virtualbox
### ISO
The installer ISO (682 MB) can be used via regular install methods (PXE,
CD, USB image, etc.) and uses the Anaconda installer to deliver the CentOS
Atomic Host.
This allows flexibility to control the install using kickstarts and define
custom storage, networking and user accounts. This is the recommended
process for getting CentOS Atomic Host onto bare metal machines, or to
generate your own image sets for custom environments.
### QCOW2
The CentOS-Atomic-Host-7-GenericCloud.qcow2 (922 MB) is suitable for use in
on-premise and local virtualized environments. We test this on OpenStack,
AWS and local Libvirt installs. If your virtualization platform does not
provide its own cloud-init metadata source, you can create your own
(http://www.projectatomic.io/blog/2014/10/getting-started-with-cloud-init/)
NoCloud iso image. The Generic Cloud image is also available compressed in
gz (389 MB) and xz compressed (303 MB) formats.

Release Cycle
-------------
The rebuild image will follow the upstream Red Hat Enterprise Linux Atomic
Host cadence. After sources are released, they’ll be rebuild and included
in new images. After the images are tested by the SIG and deemed ready,
they’ll be announced. If you’d like to help with the process, there’s
plenty to do!
Getting Involved
----------------
CentOS Atomic Host is produced by the CentOS Atomic SIG
(http://wiki.centos.org/SpecialInterestGroup/Atomic), based on upstream
work from Project Atomic (http://www.projectatomic.io/). If you’d like to
work on testing images, help with packaging, documentation, or even help
define the direction of our releases — join us!
The SIG meets weekly on Thursdays at 16:00 UTC in the #centos-devel
channel, and you’ll often find us in #atomic and/or #centos-devel if you
have questions. You can also join the atomic-devel
(https://lists.projectatomic.io/mailman/listinfo/atomic-devel) mailing list
if you’d like to discuss the direction of Project Atomic, its components,
or have other questions.
Getting Help
------------
If you run into any problems with the images or components, feel free to
ask on the centos-devel
(http://lists.centos.org/mailman/listinfo/centos-devel) mailing list.
Have questions about using Atomic? See the atomic mailing list
(https://lists.projectatomic.io/mailman/listinfo/atomic) or find us in the
#atomic channel on Freenode.
