ppc64 repository contains ppc packages
by Mihai Moldovan 15 Nov '17

15 Nov '17

Hi I noticed my ppc64 builds failing today. Going through the build logs, I noticed that yum pulled in a lot of ppc packages for no apparent reason. Blacklisting *.ppc works around this issue, but this was not necessary yesterday. Looking at http://mirror.centos.org/altarch/7/os/ppc64/Packages/ I notice a lot of ppc packages in there. I don't remember seeing them before. Is this an error, or was it done on purpose? Mihai

CERN pre-dojo meeting topic : build bots accounts for CBS
by Fabian Arrotin 14 Nov '17

14 Nov '17

Here are some notes taken from the CERN pre-dojo meeting from last week : <paste> Allow SIGs to have separate accounts for build bots - separate user accounts from "bot" accounts for security reasons - [proposal] have an email alias (not list) per sig for the bots, like sig-<bla>@centos.org pointing to the SIG's chair - [proposal] SIG chair must request or approve email alias requests/ ACO account creation sent to CentOS Board chairman </paste> So, (as also discussed yesterday in the CBS meeting - https://www.centos.org/minutes/2017/October/centos-devel.2017-10-23-14.01.l…) The proposal would be to create a @centosproject.org (or @centos.org) email alias, that would go to SIG chair, and that would be used to create an account on https://accounts.centos.org While we can manually generate x509 cert with longer validity period, we discussed the fact that using centos-cert just takes 2 seconds every 6 months, so SIG members who were present didn't find it a real issue. (email notifications go to SIG chair - and/or other members ? - in advance so easy to follow) That's probably the workflow people use already anyway, while Brian confirmed that longer-term a proper credentials store would be on the roadmap, but soon. -- Fabian Arrotin The CentOS Project | http://www.centos.org gpg key: 56BEC54E | twitter: @arrfab

New CentOS Atomic Host Available for Download
by Jason Brooks 14 Nov '17

14 Nov '17

The CentOS Atomic SIG has released an updated version[1] of CentOS Atomic Host (7.1710), a lean operating system designed to run Linux 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 This release includes an updated version of rpm-ostree that allows for more flexibility when using rpm-ostree's package layering features. CentOS Atomic Host includes these core component versions: * atomic-1.19.1-5.git48c224b.el7.centos.x86_64 * cloud-init-0.7.9-9.el7.centos.2.x86_64 * docker-1.12.6-61.git85d7426.el7.centos.x86_64 * etcd-3.2.7-1.el7.x86_64 * flannel-0.7.1-2.el7.x86_64 * kernel-3.10.0-693.5.2.el7.x86_64 * kubernetes-node-1.5.2-0.7.git269f928.el7.x86_64 * ostree-2017.11-1.el7.x86_64 * rpm-ostree-client-2017.9-1.atomic.el7.x86_64 Package Layering with rpm-ostree Using rpm-ostree package layering[2], it is possible to dynamically add more packages onto the system that are not part of the commit composed on the server. These additional "layered" packages are persistent across upgrades, rebases, and deploys. If a package you wish to layer conflicts with a package already in the atomic host image, a set of recently-added "override" commands can help resolve the conflict. [2] http://rpm-ostree.readthedocs.io/en/latest/manual/administrator-handbook/#h… For instance, the "origin-clients" package can be used to quickly stand up an OpenShift Origin install using the command `oc cluster up`, but this package conflicts with the "kubernetes-client" package that comes baked into the CentOS Atomic Host image. You can use package layering to configure the repository containing the "origin-clients" rpm, to remove the conflicting kubernetes packages, and to install "origin-clients." # rpm-ostree install centos-release-openshift-origin36 # rpm-ostree ex livefs # rpm-ostree ex override remove kubernetes-client kubernetes-node # rpm-ostree install origin-clients -r Download CentOS Atomic Host CentOS Atomic Host is available as a VirtualBox or libvirt-formatted Vagrant box, or as an installable ISO, qcow2 or Amazon Machine image. For links to media, see the CentOS wiki[3]. [3] https://wiki.centos.org/SpecialInterestGroup/Atomic/Download Upgrading If you're running a previous version of CentOS Atomic Host, you can upgrade to the current image by running the following command: # atomic host upgrade 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[4], based on upstream work from Project Atomic[5]. If you'd like to work on testing images, help with packaging, documentation -- join us! [4] http://wiki.centos.org/SpecialInterestGroup/Atomic [5] http://www.projectatomic.io/ The SIG meets every two weeks as part of the Project Atomic community meeting at 16:00 UTC on Monday in the #atomic channel. You'll often find us in #atomic and/or #centos-devel if you have questions. You can also join the atomic-devel[6] mailing list if you'd like to discuss the direction of Project Atomic, its components, or have other questions. [6] https://lists.projectatomic.io/mailman/listinfo/atomic-devel 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.

Vagrant ignores checksums, instead of validating them
by Laurentiu Pancescu 11 Nov '17

11 Nov '17

Hi there, Emmanuel Kasper of the Debian Cloud Team contacted me about two days ago: they discovered that Vagrant simply ignores any --checksum parameter when adding the box. You can even provide "1234" instead of a valid SHA256 sum, and Vagrant will just add the downloaded box, without any warning or error whatsoever: vagrant box add --checksum-type sha256 --checksum 1234 --provider libvirt --box-version 1710.01 centos/7 ==> box: Loading metadata for box 'centos/7' box: URL: https://atlas.hashicorp.com/centos/7 ==> box: Adding box 'centos/7' (v1710.01) for provider: libvirt box: Downloading: https://vagrantcloud.com/centos/boxes/7/versions/1710.01/providers/libvirt.… ==> box: Successfully added box 'centos/7' (v1710.01) for 'libvirt'! echo $? 0 Our signatures are basically useless for most users: Vagrant will only check the signature if one is included in the metadata (which is not the one in the box we host, but generated by Vagrant Cloud, formerly known as Atlas - there's simply no way to get Hashicorp's servers to include the checksum, not even for the boxes they host themselves). The --checksum argument is honored if you add a raw box, but I doubt our users would be willing to do that, even if they knew about it: $ vagrant box add --checksum-type sha256 --checksum 1234 --name c7tmp https://cloud.centos.org/centos/7/vagrant/x86_64/images/CentOS-7-x86_64-Vag… ==> box: Box file was not detected as metadata. Adding it directly... ==> box: Adding box 'c7tmp' (v0) for provider: box: Downloading: https://cloud.centos.org/centos/7/vagrant/x86_64/images/CentOS-7-x86_64-Vag… box: Calculating and comparing box checksum... The checksum of the downloaded box did not match the expected value. Please verify that you have the proper URL setup and that you're downloading the proper file. Expected: 1234 Received: 9d1ddb812de88578326538d69fdd5f59ba68adf04862144300c42d0293f61d2f $ echo $? 1 Another possibility would be to also host the metadata ourselves, along with the raw boxes, on cloud.centos.org. Endymion can already generate the needed metadata, and I already verified that Vagrant works properly with it, even detecting newer versions of the boxes for updates. The problem of convincing our users to use a cloud.c.o URL instead of Atlas still remains. I guess I'll have to replace the section in our future release announcements about verifying the images downloaded from Atlas with some sort of warning. Any other ideas of what we could do? Vagrant's behavior is described in its documentation, so I assume it's by design. How about adding the missing Vagrant functionality as distro patches, if upstream doesn't want to?
