Plan for releasing CentOS CR into CBS and CI
by Brian Stinson 30 Aug '17

30 Aug '17

Hi Folks, We've had a few discussions around how to handle releasing CR (https://wiki.centos.org/AdditionalResources/Repositories/CR) over the past few days. When we last checked in, there was still a bit of work going on building and testing pre-release CR (the QA team has been hard at work), and the altarch builds were still in progress. There are 2 ways the release might play out: - If the altarch (aarch64, and ppc64{,le}) builds are finished, and we are otherwise ready: CBS and CI will be seeded from the mirrors just like usual, and CR will be available at roughly the same time as the rest of the mirror network - If the altarch builds are not yet ready, the CentOS QA team may decide to release x86_64 ahead of the other arches. In that case, we will wait for ppc and aarch64 but still seed CI and CBS together as soon as the altarch builds are ready. If there are any questions, feel free to comment here. As always we will post updates as we move forward. Cheers! -- Brian Stinson

Duffy v2: Please send RFEs!
by Brian Stinson 28 Aug '17

28 Aug '17

Hi Folks, You're likely familiar with our node provisioner Duffy (https://wiki.centos.org/QaWiki/CI/Duffy). In order to support new features, and encourage interested folks to participate in development with us, we are gathering requirements to get started soon on Duffy Version 2. Duffy2 will be developed with an OSS license, and posted in a public repository. Some of you have pending RFEs that we'll deal with during development: - Support Fedora Images (https://bugs.centos.org/view.php?id=13626) - Support for cloud VMs in cloud.ci.centos.org - Support for VLAN Isolation on the Seamicro hardware - Support for extending an existing session (https://bugs.centos.org/view.php?id=9773) If you have a feature request for us to track let's talk about it here. If you're interested in participating in the development effort, please get in touch with me. Happy Testing! -- Brian Stinson CentOS CI Infrastructure Team

How to add new credentials?
by Michal Srb 28 Aug '17

28 Aug '17

Hello, I am adding new jobs for devtools/fabric8-analytics projects via [1], but I'd also need to add new credentials (API key) to Jenkins that I could later use in E2E tests. Is there documentation somewhere on how to do that? Can someone please point me in the right direction? I have the API key, I know how to later use it in my jobs, I just don't know how to add it to Jenkins. Thanks, Michal [1]: https://github.com/almighty/almighty-jobs

ppc64le support in ci.centos.org is Released
by Brian Stinson 19 Aug '17

19 Aug '17

Hi Folks, We've been working over the last few weeks on our node provisioner, duffy, so that jobs in CICO can request nodes for architectures besides x86_64. We have deployed that code into production and have some ppc64le VMs ready to take work. To see the flavors available including memory/vcpu/disk sizing, and to view sample duffy calls please visit: https://wiki.centos.org/QaWiki/CI/Multiarch Potential Questions: -------------------- - What about aarch64? Support for aarch64 is coming as soon as we finish installing the hardware for this (probably soon after the CentOS Linux 7.1708 release). We'll use the same pattern as ppc64le for the aarch64 VMs. - Can I request nodes using cicoclient? There is a pull request pending, a release announcement will follow when this is merged. https://github.com/CentOS/python-cicoclient/pull/14 The relevant documentation for making calls using cioclient is on the wiki page. Multiarch Next Steps: --------------------- We plan on using these machines to begin exploring multiarch additions to openshift and openstack in ci.centos.org Happy Friday! -- Brian Stinson CentOS CI Infrastructure Team

CR and CiCo
by Karanbir Singh 08 Aug '17

08 Aug '17

hi, with the next release coming up - the CR repos are going to get populated ahead of the distro release itself - typically, this can be a week or so ahead. What this means to cico tenants is that their machines, when yum updated, will reflect the content in the next release. Any user, on or off cico, with the cr-repo enabled, will be in the same situation. However, cbs.centos.org will NOT have the CR/ content added in till AFTER the release is done for media. With a week to 10 day gap between the two events, if you tenant needs to manage this issue, please do. However, if you do find issues in the builds and tests, please let us know - a good goal is to have all SIG content validated ahead of the next-release, or to handle any problems that the users might see, ahead of time. please feel free to reach out on irc, lists, emails, phones etc i regards -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

Real SSL Certificates installed on apps.ci.centos.org
by Brian Stinson 01 Aug '17

01 Aug '17

Hi Folks, We recently got a trusted certificate for apps.ci.centos.org I just finished up installing this for all the existing routes, and enabled it as the cert for the console. This did require us to move the publicURL for the console to https://console.apps.ci.centos.org:8443, redirects should automatically get you to the right place if you're using the old ones. If there are any questions, let me know. Cheers! -- Brian Stinson

AltArch support in CI (status update)
by Fabian Arrotin 26 Jul '17

26 Jul '17

Hi, Just starting a thread on the list so that various projects having a need to test their builds on AltArch (aarch64/ppc64/ppc64le) within CI are aware of the following : Thanks to Brian, who coordinated with several folks, we'll be able soon to provide access to aarch64/ppc64/ppc64le nodes within ci.centos.org. So far we have configured/deployed/tested ppc64/ppc64le in the environment, so that we can automate the whole thing happening behind the scene (basically ansible being called for this, the same way it's actually done for x86_64). The last thing to do is now to make Duffy (https://wiki.centos.org/QaWiki/CI/Duffy) aware of those "other arches" nodes to be able to - hand over those nodes on specific request - reinstall those automatically by calling correct playbooks Worth noting that due to the amount of physical nodes for those AltArches, we'll not be able to provide you access to bare metal nodes, but rather to VMs running on those (at least for ppc64/ppc64le). That shouldn't be a problem as we'll be able to distribute resources so that you'll have multiple vcpus per VM, and for Power8, our hypervisors are installed with CentOS 7 ppc64le, that uses the kvm_hv module. That then means that it's possible to use nested virt (if needed) as it will then use the kvm_pr for this, slower, but works (http://wiki.qemu.org/Documentation/Platforms/POWER) If you have remark/comments, feel free ! -- Fabian Arrotin The CentOS Project | http://www.centos.org gpg key: 56BEC54E | twitter: @arrfab
