A short introduction
by Laurentiu Pancescu 29 Feb '16

29 Feb '16

Hello everyone, Could you perhaps use some help? My name is Laurentiu, I'm based in southwestern Germany, and I would like to help with the Vagrant images from the CentOS Cloud Instance SIG. A bit of background information: I started using Linux in 1997, with Red Hat Linux 4.2, switched to Slackware 7.0 a few years later (due to issues with gcc-2.96), then Debian from 2001 until about two years ago, when I switched to Fedora. Unfortunately, my experience with system administration is limited to workstations and running standalone (Debian) servers. I'm more of a software developer: I was a graduate teaching assistant at a University for a couple of years, followed by around 9 years in R&D for an international corporation (where I worked pretty much everywhere in code bases containing tens of millions of lines of code - I spent more than half of the time writing C++ for a couple of real-time operating systems, debugging hardware and turning on boards and ASICs, the rest being Windows development and a bit of Perl for the code generators and the release system), learning just enough system administration to get stuff done. Besides C++, I know Python, as well as some Perl and Bourne shell scripting. Best regards, Laurentiu Pancescu

signing a vagrant box
by Karanbir Singh 29 Feb '16

29 Feb '16

hi folks, does anyone have insight into signing a vagrant box, so the origin can be confirmed ? A brief look around seems to indicate there is no such support in vagrant itself ? Surely, I must be missing something. Regards -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

New CentOS Atomic Host Images Available for Download
by Jason Brooks 26 Feb '16

26 Feb '16

An updated version of CentOS Atomic Host (version 7.20160224) is now available for download[1]. CentOS Atomic Host is 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. [1] https://wiki.centos.org/SpecialInterestGroup/Atomic/Download CentOS Atomic Host is available as a VirtualBox or libvirt-formatted Vagrant box, or as an installable ISO, qcow2 or Amazon Machine image. These images are available for download at cloud.centos.org. The backing ostree repo is published to mirror.centos.org. CentOS Atomic Host includes these core component versions: - kernel-3.10.0-327.10.1.el7.x86_64 - cloud-init-0.7.5-10.el7.centos.1.x86_64 - atomic-1.6-6.gitca1e384.el7.x86_64 - kubernetes-1.2.0-0.6.alpha1.git8632732.el7.x86_64 - etcd-2.2.2-5.el7.x86_64 - ostree-2016.1-2.atomic.el7.x86_64 - docker-1.8.2-10.el7.centos.x86_64 - flannel-0.5.3-9.el7.x86_64 Upgrading If you're running a previous version of CentOS Atomic Host, you can upgrade to the current image by running the following command: $ sudo atomic host upgrade Images Vagrant CentOS-Atomic-Host-7-Vagrant-Libvirt.box (421 MB) and CentOS-Atomic-Host-7-Vagrant-Virtualbox.box (435 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 (742 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 image allows users to control the install using kickstarts and to define custom storage, networking and user accounts. This is the recommended option for getting CentOS Atomic Host onto bare metal machines, or for generating your own image sets for custom environments. QCOW2 The CentOS-Atomic-Host-7-GenericCloud.qcow2 (1 GB) image 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 NoCloud iso image. Amazon Machine Images Region Image ID ------ -------- us-east-1 ami-e6d5e88c us-west-2 ami-3fb05d5f us-west-1 ami-fd62129d eu-west-1 ami-451ea236 eu-central-1 ami-ce8663a1 ap-southeast-1 ami-6c4c850f ap-northeast-1 ami-c74644a9 ap-southeast-2 ami-bae8ced9 ap-northeast-2 ami-5732fc39 sa-east-1 ami-059d1f69 SHA Sums d4e43826fc9f641272e589dfb8d979cd592809b34cdbdaee8b7abc9a09ff30d2 CentOS-Atomic-Host-7.1602-GenericCloud.qcow2 33bd4f732c2857c698bd00bc6db29ae2a4d7d0b768f0353d4e28a5c5ab1c999e CentOS-Atomic-Host-7.1602-GenericCloud.qcow2.gz ee9d9b4d78906ea9c33b0b87c8ad3387e997b479626e64ffedfd3f415a84cded CentOS-Atomic-Host-7.1602-GenericCloud.qcow2.xz 39a548f95022a9ab100d64dbf3579d40c66add1bc56ca938b7dba38b73c2ea87 CentOS-Atomic-Host-7.1602-Installer.iso 2f965b2a502c3839b6be84dee5ee4e60328d9f074e1494ded58b418a309df060 CentOS-Atomic-Host-7.1602-Vagrant-Libvirt.box bc976d197cac629fd68a6d8faf6bcfaeca8afd0020bf573ef343622a7ae1581b CentOS-Atomic-Host-7.1602-Vagrant-Virtualbox.box Release Cycle The CentOS Atomic Host image follows the upstream Red Hat Enterprise Linux Atomic Host cadence. After sources are released, they're rebuilt and included in new images. After the images are tested by the SIG and deemed ready, we announce them. Getting Involved CentOS Atomic Host is produced by the CentOS Atomic SIG, based on upstream work from Project Atomic. If you'd like to work on testing images, help with packaging, documentation -- 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 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 mailing list. Have questions about using Atomic? See the atomic mailing list or find us in the #atomic channel on Freenode.

[StorageSIG] ceph on centos6
by daniel.vanderster＠cern.ch 26 Feb '16

26 Feb '16

Hi all, I've been directed here by ktdreyer in the ceph-devel irc. Today we learned that ceph hammer is no longer being built for centos6, so we won't be getting 0.94.6 or newer. AFAICT, it was dropped due to complications in their build system: https://github.com/ceph/ceph-build/commit/42c7cb3f412e9fc1f525a037f07697fc8… Would it make sense for the Storage-SIG to build hammer on centos6? Technically it should be doable -- but would you guys need some help getting this going? Eventually (client only) builds of jewel on el6 would be really nice to have, but I don't yet know if that's even possible. Cheers, Dan van der Ster CERN IT Storage Group Ceph Community "Academic Liaison"

Cloud images: what's current / release notes / hashes?
by Beni Paskin-Cherniavsky 26 Feb '16

26 Feb '16

Hi. [Follow up from https://github.com/openshift/openshift-ansible/issues/1384] I did not RTFM, this is a fresh-eyes-I-just-want-to-download-an-image perspective... Looking at http://cloud.centos.org/centos/7/images/, I see -1602 is latest version. - If for some reason I want to use the unversioned CentOS-7-x86_64-GenericCloud.* files, it's hard to be sure what I'll get (other than by downloading => I am getting 1602). - sha256sum.txt{,.asc} contain no hashes for the unversioned files. File size does suggest it's 1602. Ideally the file listing would actually show them as "name -> target" symlink, and/or downloading would return an HTTP redirect to the current version. Currently it returns the content directly, only identifying headers are `Last-Modified: Tue, 23 Feb 2016 17:53:08 GMT` and `ETag: "fcc0480-52c739f3d2900"` (for the .xz). [Be careful with redirect: some scripts/libraries by default don't follow them, e.g. any script using `curl` without `-L` would break :-(] - http://cloud.centos.org/centos/7/images/sha256sum.txt{,.asc} are not available over HTTPS. I can verify the hash but I can't trust the hash itself. That's what .asc is signed for, but lazy folks like me don't necessery know which key to trust... (`gpg --search-keys F4A80EB5` worked but then `gpg --verify` says "WARNING: This key is not certified with a trusted signature!". No idea what that means - I'm clueless with GPG; trusting https://cloud.centos.org would be trivial for me.) Looking at https://wiki.centos.org/Download: - It only links to the unversioned cloud images, doesn't say it's 1602 (other places on that page give the impression everything 7 is 1511), and doesn't list hashes. - I don't see a link to release notes for cloud images; https://wiki.centos.org/Manuals/ReleaseNotes/CentOS7 is for 1511 and only talks of the regular ISOs. https://wiki.centos.org/Cloud doesn't mention any specific versions, release notes or hashes either. Googling "centos cloud 1602" didn't lead me to any "official" announcement. Nothing on centos-announce this February. Is -1602 "officially" released? (I personally don't really care, but "what changed" is the first natural question people ask beyond "I just want the latest"...) Hope this is useful feedback.

Automated build failures on dockerhub
by Jim Perrin 25 Feb '16

25 Feb '16

Those of you using the automated build functionality of docker's hub may have been experiencing some build failures lately. It appears that docker has migrated to something using a different graph driver on the back-end or have otherwise limited the capabilities available during the build process. The result is that builds with packages like httpd will fail, because they require the cap_set_file privilege as part of the install process. There have been a few bugs filed with the Docker folks for this, but I don't know what the end result of this will be. For now, if you use the automated build framework on dockerhub, be aware that your builds may fail, and it's outside our control. -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77

[unscheduled outage] : DevCloud
by Fabian Arrotin 25 Feb '16

25 Feb '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Today in the evening we suffered from a big power outage that affected some of our infra services. Some small public services like : - - planet.centos.org - - seven.centos.org were down, but connection was restored and services back online. We had to spend more time on the DevCloud setup (https://wiki.centos.org/DevCloud) : we first had to verify the underlying block devices and status for that gluster setup (in Distributed/Replicated mode), and then slowly restart the hypervisor controller and then Virtual Machines. From a kvm hypervisor level, all VMs are powered back on, but we haven't verified each VM (and so the status) If you recently deployed some VMs in that DevCloud enviroment, verify that you can still reach your testing VMs. Sorry for the inconvenience. On behalf of the infra team, - -- Fabian Arrotin The CentOS Project | http://www.centos.org gpg key: 56BEC54E | twitter: @arrfab -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iEYEARECAAYFAlbOSioACgkQnVkHo1a+xU6KSACgmrfAEbzynNR3ef8It7du0e65 /xsAn3OmZZljXugAU31E129Iv58flyfY =xT0k -----END PGP SIGNATURE-----

[Storage SIG] Ceph Hammer 0.94.5 is out
by François Cami 24 Feb '16

24 Feb '16

Hi, The first release of Ceph Hammer by the Storage SIG is available on CentOS 7 x86_64 for testing purposes. It is mainly intended as a preview release as we are still working on the release process and associated documentation. A quickstart guide is available in the wiki: https://wiki.centos.org/SpecialInterestGroup/Storage/ceph-Quickstart We are of course looking for feedback from potential Ceph users on CentOS, especially from the Virtualization (oVirt), Cloud/RDO and Atomic Host SIGs. Our next steps are updating to 0.94.6, working on CI, and completing the quickstart guide. Co-maintainers are welcome of course! Cheers François

[Cloud SIG] OpenStack test day, March 10, 11
by Rich Bowen 24 Feb '16

24 Feb '16

TL;DR: * Mitaka 3 test day, March 10, 11: https://www.rdoproject.org/testday/mitaka/milestone3/ * On-site test day in Brno: https://www.rdoproject.org/testday/mitaka/brno-on-site/ * Demo of deploying with TripleO: https://www.youtube.com/watch?v=4O8KvC66eeU Mitaka milestone 3 is scheduled for the week of February 29 - March 4 [1] and, as per usual, we're planning a test day about a week out from that - March 10th and 11th. We've got the usual page of instructions [2] for testing. This time, however, we have two bonus events. First, we're delighted that Eliska Malikova is putting together an on-site test day at the Red Hat office in Brno, for anyone in that general area. If you wish to attend, please register [3] so that we know how much pizza to order. (Attendance is limited to 50, so please register sooner rather than later.) Second, as we attempt to get more people testing TripleO (formerly known as RDO Manager), John Trownbridge (that's Trown on IRC) will be doing a demo of the TripleO Quickstart. This will be conducted as a YouTube live stream [4] and will also be recorded, and available at that same location after the fact. So, please, come help us ensure that Mitaka is the best RDO yet. As usual, we'll be on #rdo (on Freenode IRC), and here on rdo-list, to field any questions. Full details are on the test day website [5] and, a usual, we can use lots of help making the test case instructions better, so that more people can participate. Thanks! --Rich [1] http://releases.openstack.org/mitaka/schedule.html [2] https://www.rdoproject.org/testday/mitaka/milestone3/ [3] https://www.eventbrite.com/e/rdo-on-site-test-day-brno-tickets-5934822213 [4] https://www.youtube.com/watch?v=4O8KvC66eeU [5] https://www.rdoproject.org/testday/mitaka/milestone3/ -- Rich Bowen - rbowen(a)redhat.com OpenStack Community Liaison http://rdoproject.org/
