Announcing a New CentOS Atomic Host Release
by Jason Brooks 10 Sep '15

10 Sep '15

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. ### Amazon Machine Images Region Image ID ------ -------- sa-east-1 ami-47ed785a ap-northeast-1 ami-3458d234 ap-southeast-2 ami-05511e3f us-west-2 ami-a5b6ab95 ap-southeast-1 ami-dc99938e eu-central-1 ami-8c111191 eu-west-1 ami-0b6e4d7c us-west-1 ami-69679d2d us-east-1 ami-69c3aa0c ### SHA Sums a132d59732e758012029a646c466227f4ecf0c71cc42f0a10d3672908e463c0c CentOS-Atomic-Host-7.20150908-GenericCloud.qcow2 aad5d39e0683dc997f34902b068c7373aac3f7dc9b2c962a6ac0fe7394e2aa58 CentOS-Atomic-Host-7.20150908-GenericCloud.qcow2.gz c8432175a012e7f13b7005fe9c1fe43e03e47ca433db8230ab6d5d1831d2cbe0 CentOS-Atomic-Host-7.20150908-GenericCloud.qcow2.xz b222702942d02da2204581de6f877cf93289459a99f9080e29016e3b90328098 CentOS-Atomic-Host-7.20150908-Installer.iso 5531fa99429b38c6e6c4aca87672bd5990ab90f6445cc0e55c9121ad62229141 CentOS-Atomic-Host-7.20150908-Vagrant-Libvirt.box bdcf58772117dd3a84100e5902f4f345daeea7c04f057c0ab6e29bfef3c82eab CentOS-Atomic-Host-7.20150908-Vagrant-Virtualbox.box 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.

Atomic SIG: Joint Test Day with Fedora Atomic Folks
by Dusty Mabe 10 Sep '15

10 Sep '15

Hi All, There has been some discussion of doing a joint test day with Fedora and CentOS atomic folks. Fedora is having a test day for Fedora Cloud base on 9/8 (all are welcome to join us). We were thinking about having the joint Fedora/CentOS test day on the following Tuesday (9/15). Is this something everyone is interested in? To do the test day it would be worth having a test day page like [1] and some test cases for people to execute. These test cases can probably overlap with the one's fedora has.

I'm amenable to doing just one joint meeting or finding some way to merge them, though. Also cc'ing the CentOS devel list. -- Joe Brockmeier | Community Team, OSAS jzb(a)redhat.com | http://community.redhat.com/ Twitter: @jzb | http://dissociatedpress.net/

Possible Corrupt Centos 7 Cloud Image
by Neil Wilson 03 Sep '15

03 Sep '15

Hi, I’ve had complaints from customers that the compressed qcow image on cloud images for CentOS 7 is corrupt - failing with an XFS panic. CentOS-7-x86_64-GenericCloud-20150628_01.qcow2c The raw and the uncompressed qcow2 image appear fine. If I compress the raw image to a qcow2c with qemu-img convert -p -c -O qcow2 CentOS-7-x86_64-GenericCloud-20150628_01.raw CentOS-7-x86_64-GenericCloud-20150628_01.qcow2c then I get the same size as the downloaded file but with binary differences. Could somebody take a look? Rgs Neil Wilson

[X-POST] New guide focusing cloud users
by Kushal Das 03 Sep '15

03 Sep '15

Hi all, i started a new guide [1] focusing Cloud users. Currently we have different guides spread over different wiki pages, and blog posts. But we don't have any single place which at least points to the current and updated docs. I first suggested about this during Flock cloud working group meeting. The docs are written using reStructured Text format, using sphinx project. When Fedora docs team comes up with the new tooling, they can just pull in the files from here. The source can be found at [2]. Right now it contains a very few things I just put in today. Because i am using readthedocs.org here, any commit will be reflected on the docs very fast. I am yet to add the download chapter. Feel free to add anything you think is important for our users, PR(s) are always welcome.
