CentOS Community Container Pipeline: re-architecture migration window
by Bamacharan Kundu 03 Oct '18

03 Oct '18

Hi, Since last few months, we were working on re-architecturing the CentOS Community Container Pipeline Service to make https://registry.centos.org as a stable and reliable source for CentOS based container images. We are now done with the changes for better throughput and stability. We are working on deploying the new service in production in coming weekend (between 28th Sep 2018- 1st Oct 2018). During this time service will be in maintenance mode. We will not be building new images for registry.centos.org. Existing images will not be updated based on RPM, or git source updates. However, during this migration registry.centos.org will be available to pull images from. We are trying to make sure the down time for CentOS Community Container pipeline service is minimal. Service: https://registry.centos.org Maintenance window: Service will not have downtime Impact: Users will be able to pull images from https://registry.centos.org Service: CentOS Container Community Pipeline Service Maintenance window: 28th Sep 2018 to 1st Oct 2018 (We are working on to make it minimal) Impact: PRs to https://github.com/centos/container-index will not be merged and no image updates are pushed to registry.centos.org. Sorry for the inconvenience, we will keep posted. Regards Bama Charan Kundu

Problems with qemu-img when generating Vagrant images
by Laurentiu Pancescu 02 Oct '18

02 Oct '18

Hello everyone, we switched from using qemu-img from CentOS 7.x to qemu-img-ev from the Virt SIG several months ago, to allow us to generate Hyper-V images. My attempts to build Vagrant images are failing the automated tests since the beginning of July, apparently due to corrupt filesystems. I see XFS metadata corruption in the CentOS 7 images when using qemu-img-ev, as well as ext4 superblock corruption in the CentOS 6 images.[1] The distro installer runs just once and the resulting disk image is converted by Image Factory to different formats, depending on the virtualization target. Since the VirtualBox images are working as expected, while the libvirt images don't even boot due to filesystem corruption, I would assume that the installation produces a valid image, but the conversion of the disk images for libvirt-kvm fall prey to bugs in qemu-img-ev and the stock qemu-img. If anyone has the possibility to test with VmWare or Hyper-V, please write me off-list. I noticed that qemu-img-ev is at version 2.1.2, while Debian Stable has version 2.8 and Fedora 28 has version 2.11. Maybe such bugs, if real, were already fixed upstream - would it be possible to use a newer version than what qemu-img-ev provides? We reverted to using the EL7 qemu-img, but this still produces broken libvirt images and wețd have to drop the Hyper-V images as well. Any help or suggestions are appreciated. Best regards, Laurențiu [1] https://people.centos.org/bstinson/vagrant/c6-vagrant.png

[ppc64le] Request for publishing sensu in ppc64le opstools
by Michael Turek 25 Sep '18

25 Sep '18

Hello, Trevor Vardeman <Vorrtex>, Adam Kimball <baha>, and myself <mjturek> have been looking into TripleO container builds for ppc64le. This led to finding some missing dependencies. The current one we're struggling with is sensu. It seems like all of the dependencies for running sensu are published in ppc64le-opstools [0]. Additionally, the sensu package itself is noarch. Is there anything we could do to get this package published? Thanks! Mike Turek <mjturek> [0] http://mirror.centos.org/altarch/7/opstools/ppc64le/sensu/

mirrorlist code updated / SIGs and AltArch support rolled-in
by Fabian Arrotin 24 Sep '18

24 Sep '18

<paste> Recently I had to update the existing code running behind mirrorlist.centos.org (the service that returns you a list of validated mirrors for yum, see the /etc/yum.repos.d/CentOS*.repo file) as it was still using the Maxmind GeoIP Legacy country database. As you can probably know, Maxmind announced that they're discontinuing the Legacy DB, so that was one reason to update the code. Switching to GeoLite2 , with python2-geoip2 package was really easy to do and so was done already and pushed last month. But that's when I discussed with Anssi (if you don't know him, he's maintaining the CentOS external mirrors DB up2date, including through the centos-mirror list ) that we thought about not only doing that change there, but in the whole chain (so on our "mirror crawler" node, and also for the isoredirect.centos.org service), and random chat like these are good because suddenly we don't only want to "fix" one thing, but also take time on enhancing it and so adding more new features. The previous code was already supporting both IPv4 and IPv6, but it was consuming different data sources (as external mirrors were validated differently for ipv4 vs ipv6 connnectivity). So the first thing was to rewrite/combine the new code on the "mirror crawler" process for dual-stack tests, and also reflect that change o nthe frontend (aka mirrorlist.centos.org) nodes. While we were working on this, Anssi proposed to also not adapt the isoredirect.centos.org code, but convert it in the same python format as the mirrorlist.centos.org, which he did. Last big change also that was added is the following : only some repositories/architectures were checked/validated in the past but not all the other ones (so nothing from the SIGs and nothing from AltArch, so no mirrorlist support for i386/armhfp/aarch64/ppc64/ppc64le). While it wasn't a real problem in the past when we launched the SIGs concept, and that we added after that the other architectures (AltArch), we suddenly started suffering from some side-effects : * More and more users "using" RPM content from mirror.centos.org (mainly through SIGs - which is a good indicator that those are successful, which is a good "problem to solve") * We are currently losing some nodes in that mirror.centos.org network (it's still entirely based on free dedicated servers donated to the project) To address first point, offloading more content to the 600+ external mirrors we have right now would be really good, as those nodes have better connectivity than we do, and with more presence around the globe too, so slowly pointing SIGs and AltArch to those external mirrors will help. The other good point is that , as we switched to the GeoLite2 City DB, it gives us more granularity and also for example, instead of "just" returning you a list of 10 validated mirrors for USA (if your request was identified as coming from that country of course), you now get a list of validated mirrors in your state/region instead. That means that then for such big countries having a lot of mirrors, we also better distribute the load amongst all of those, which is a big win for everybody - users and mirrors admins - ) For people interested in the code, you'll see that we just run several instances of the python code, behind Apache running with mod_proxy_balancer. That means that if we just need to increase the number of "instances", it's easy to do but so far it's running great with 5 running instances per node (and we have 4 nodes behind mirrorlist.centos.org). Worth noting that on average, each of those nodes gets 36+ millions requests per week for the mirrorlist service (so 144+ millions in total per week) So in (very) short summary : mirrorlist.centos.org code now supports SIGs/AltArch repositories (we'll sync with SIGs to update their .repo file to use mirrorlist= instead of baseurl= soon) we have better accuracy for large countries, so we redirect you to a 'closer' validated mirror </paste> So that means that now the following combination are possible through mirrorlist: testing base os for aarch64 : curl 'http://mirrorlist.centos.org/?release=7&arch=aarch64&repo=os' testing RDO Rocky release for ppc64le : curl 'http://mirrorlist.centos.org/?release=7&arch=ppc64le&repo=cloud-openstack-r…' And so on .... :) There is no "pressure" to update your -release pkg to switch from baseurl=mirror.centos.org to mirrorlist=mirrorlist.centos.org but I just wanted to inform that it's now "live" and you can start thinking about that change, and why not with an update pkg just pushed to -testing (aka buildlogs.centos.org) and then move to that later ?

The full schedule is available at https://releases.openstack.org/stein/schedule.html. Twice during each release cycle, RDO hosts official Test Days shortly after the first and third milestones; therefore, the upcoming test days are 01-02 November 2018 for Milestone One and 14-15 March 2019 for Milestone Three. Get Started There are three ways to get started with RDO. To spin up a proof of concept cloud, quickly, and on limited hardware, try an All-In-One Packstack installation <https://www.rdoproject.org/install/packstack/>. You can run RDO on a single node to get a feel for how it works. For a production deployment of RDO, use the TripleO Quickstart <https://www.rdoproject.org/tripleo/> and you’ll be running a production cloud in short order. Finally, for those that don’t have any hardware or physical resources, there’s the OpenStack Global Passport Program <https://www.openstack.org/passport>. This is a collaborative effort between OpenStack public cloud providers to let you experience the freedom, performance and interoperability of open source infrastructure. You can quickly and easily gain access to OpenStack infrastructure via trial programs from participating OpenStack public cloud providers around the world. Get Help The RDO Project participates in a Q&A service at https://ask.openstack.org. We also have our [users(a)lists.rdoproject.org[( https://lists.rdoproject.org/mailman/listinfo/users) for RDO-specific users and operrators. For more developer-oriented content we recommend joining the dev(a)lists.rdoproject.org mailing list <https://lists.rdoproject.org/mailman/listinfo/dev>. Remember to post a brief introduction about yourself and your RDO story. The mailing lists archives are all available at https://mail.rdoproject.org <https://lists.rdoproject.org/mailman/listinfo>. You can also find extensive documentation on RDOproject.org <https://www.rdoproject.org/>. The #rdo channel on Freenode IRC is also an excellent place to find and give help. We also welcome comments and requests on the CentOS mailing lists <https://lists.centos.org/mailman/listinfo> and the CentOS and TripleO IRC channels (#centos, #centos-devel, and #tripleo on irc.freenode.net), however we have a more focused audience within the RDO venues.
