Feedback needed: ideas for the Vagrant images
by Laurentiu Pancescu 11 Jul '16

11 Jul '16

Hi there, I would appreciate some feedback on a few ideas for our Vagrant images. Our CentOS images for Vagrant are currently not setup according to the upstream recommendations for base boxes, and I'd like to change that. [1] Here's the list of necessary modifications: I. root password should be 'vagrant': already filed by Lalatendu Mohanty as issue #30 on GitHub [2]. I should mention that Karanbir Singh has some reservations related to security. However, the box already has passwordless sudo, and changing the root password is just a "sudo passwd" away (I tried, it warns about a bad password, but it accepts it). Although public key auth is enabled, password-based authentication isn't disabled, and sshd will happily let anyone log in to any public box as vagrant:vagrant. We should probably only allow local password logins (on the console), for both root and vagrant; not sure if the best way to enforce this is sshd_config or PAM. II. use /vagrant as the sync directory: we currently use /home/vagrant/sync, this change is already planned for the release following 1606 III. "UseDNS no" in sshd_config: this would make connections via ssh faster Additional ideas for optimization: IV. disable requiretty in /etc/sudoers: this allows users to enable the pipelining feature of the Ansible provisioner, which significantly increases its speed (it's about 2 times faster in my tests). [3] V. set GRUB_TIMEOUT to 1 or 0: this reduces or eliminates the waiting time before the default kernel is booted (the VM runs generally without a display, so it makes no sense to wait there) Best regards, Laurențiu [1] https://www.vagrantup.com/docs/boxes/base.html [2] https://github.com/CentOS/sig-cloud-instance-build/issues/30 [3] https://docs.ansible.com/ansible/intro_configuration.html#pipelining

Rebuilding RDO for ppc64le
by Xiandong Meng 11 Jul '16

11 Jul '16

In RDO Austin BOF meeting, I have proposed to rebuild RDO packages for ppc64le. And a few discussions have been carried over since then. Now with the power builders up and running on cbs (http://cbs.centos.org/koji/hosts) I'd like to write to the mailinglist for more broad discussing. The goal is to rebuild RDO packages for ppc64le in CBS. And we will start with Mitaka release as it is a recent stable release. And one of the idea was to 1. create a new tag (cloud7-openstack-mitaka-candidate-ppc64le?) 2. import all 'noarch' builds from cloud7-openstack-mitaka-* tags 3. send all required packages to the builder 4. test resulting packages for installation & function validation (via ci pipeline?) 5. import/merge all of them to propose cloud7-openstack-* tag I think we need to proceed with this work without touching x86 tags until it is ready for merge. I have experience building the packages with local mock build environment, but i may need help to initiate that build work in CBS. Any comments/suggestions are welcome. Regards, Alex Meng <mengxiandong(a)gmail.com> mengxiandong(a)gmail.com

[cockpit] Broken dependencies in CentOS Extras
by Haïkel 08 Jul '16

Hi, while running repoclosure on Cloud SIG repositories, I found out that cockpit had missing dependencies. <snip> Last metadata expiration check: 0:00:02 ago on Wed Jul 6 19:53:59 2016. package: cockpit-ostree-0.108-1.el7.centos.x86_64 from centos-extras unresolved deps: rpm-ostree-client >= 2015.11-1 /usr/libexec/rpm-ostreed package: cockpit-selinux-0.108-1.el7.centos.noarch from centos-extras unresolved deps: setroubleshoot-server >= 3.3.3 </snip> Could be fine, but it's best to check with you guys.

New CentOS Atomic Host release available for download
by Jason Brooks 08 Jul '16

08 Jul '16

An updated version of CentOS Atomic Host (tree version 7.20160707) is now available for download[1], featuring updated versions of docker (1.10.3) and the atomic run tool (1.10.5). 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: - docker-1.10.3-44.el7.centos.x86_64 - kubernetes-1.2.0-0.12.gita4463d9.el7.x86_64 - kernel-3.10.0-327.22.2.el7.x86_64 - atomic-1.10.5-5.el7.x86_64 - flannel-0.5.3-9.el7.x86_64 - ostree-2016.5-3.atomic.el7.x86_64 - etcd-2.2.5-2.el7.0.1.x86_64 - cloud-init-0.7.5-10.el7.centos.1.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 (467 MB) and CentOS-Atomic-Host-7-Vagrant-Virtualbox.box (477 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 (751 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 (1.1 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.

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.

You are right. I am sometimes still lost in CentOS repository structure. What is in x86-64 virt/kvm-common repository is present in os/ one for aarch64 already. Only qemu-kvm-ev update (2.7.1 -> 2.10.1) would be nice to have. So we can kill that dependency from centos-release-openstack-mitaka package. Added note to the bug (I lack permissions to close it as notabug).

CBS users : x509 user certificates expiring policy
by Fabian Arrotin 06 Jul '16

06 Jul '16

Due to some reports in #centos-devel on irc.freenode.net, we thought it would be good to send a reminder at least on this list about the x509 cert/policy for cbs.centos.org : If you have an account on https://accounts.centos.org and are an active builder/developer using https://cbs.centos.org to build pkgs for one or multiple SIGs, it's worth knowing that initially we had the ~6 months validity period for certificates generated through ACO. We documented the "Expired Certificate" error on the dedicated wiki page (see https://wiki.centos.org/HowTos/CommunityBuildSystem?#head-e81bf95796a59cbfd…) but it seems some people forgot about it. So this is just a reminder that you'd have to check if your cert is still valid if you're using cbs.centos.org. On our side, we're working on an automated email reminder that would be sent to people having their certs expired or near expiring date. That way you'll know that you just have to use centos-cert (https://wiki.centos.org/HowTos/CentosPackager) to recreate a new cert (and that step will automatically revoke the previous one) If you have any questions, feel free to discuss this here or in #centos-devel on irc.freenode.net -- Fabian Arrotin The CentOS Project | http://www.centos.org gpg key: 56BEC54E | twitter: @arrfab

python-centos-0.1.1-1 Released, centos-packager built for f24 certificate expiration
by Brian Stinson 05 Jul '16

05 Jul '16

Hi Folks, I've released an update to python-centos that fixes an issue when running `centos-cert -v`. The tool will now check the expiration date of your accounts.centos.org user certificate and report it invalid if it's expired. You should find python-centos-0.1.1-1 in CentOS-Extras shortly. I also used this opportunity to publish builds for the centos-packager suite in COPR for Fedora 24, you can find those here: https://copr.fedorainfracloud.org/coprs/bstinson/centos-packager/ If you have any feedback or questions, let us know here. Cheers! -- Brian

next steps for altarch with ceph and openstack
by Jim Perrin 05 Jul '16

05 Jul '16

With the work that Marcin has done for openstack on aarch64, as well as the ceph builds, we need to begin working a plan for publishing these builds to a mirror. I'd like to identify the steps needed, and the ownership for those steps. Thomas please correct/update these as needed 1. new tag in cbs for aarch64 build, with modified dist for mitaka. Will ceph need this as well? 2. If we wish to re-use the centos-release-openstack-mitaka noarch, dependencies of centos-release-ceph-hammer, centos-release-qemu-ev, centos-release-storage-common, and centos-release-virt-common need to be addressed. Alternately we could create a centos-release-openstack-mitaka-experimental for now if it can work stand-alone. 3. Mirror locations on buildlogs and mirrors need to be created and tested. Possible adjustments to existing -release files due to the /altarch/ vs centos path differences. 4. Package signing. This should already work with existing infra, but need to test and validate. -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77
