Planned outage : Duffy CI infra migration phase 1 on August 1st
by Fabian Arrotin 28 Jul '22

28 Jul '22

As previously announced in June (see https://lists.centos.org/pipermail/ci-users/2022-June/004547.html and also https://www.youtube.com/watch?v=aqgs-3NnRmA) we'll migrate existing Duffy API service to the new Duffy v3, starting with Phase 1 . Migration is scheduled for """"Monday August 1st 7:00 am UTC time"""". You can convert to local time with $(date -d '2022-08-01 07:00 UTC') The expected API downtime will be under the 60 seconds (DNS TTL). Worth knowing: - new duffy api (in legacy mode) has currently less available nodes, but that will be resolved during the day (see below) - we'll have to wait ~6h (default maximum "lease" time for a test node) to be able to let new duffy api reinstall older seamicro nodes and so be available in the new duffy v3 pool (transitioning from old to new duffy pool) - currently running jobs will continue so to work, but when you'll hit new duffy api endpoint (DNS switch) to "return nodes" it will just answer that session doesn't exist (new one) but it's safe to ignore As soon as new duffy API is available you'll already be able to switch your workflow to new the Duffy API and so use the new features. Tenants/users documentation about how to interact with Duffy is available on https://sigs.centos.org/guide/ci/ (see the Duffy part of that documentation) That means that switching to EC2 nodes will be directly possible. During the day we'll tune the duffy nodepool configuration based on usage metrics. IMPORTANT remark : *only* projects/tenants that opted-in in the last 45 days are currently migrated (api and ssh keys), so if you haven't (yet), you can still opt-in, otherwise all your requests for duffy ephemeral nodes will be declined by new duffy api service next monday. In case of troubles, both Pedro (nick phsmoura) and myself (nick arrfab) will be also present in the #centos-ci irc channel on irc.libera.chat the whole day. Thanks for your understanding and patience. on behalf of the Infra team, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab

Updated cico-workspace container image for openshift (please read)
by Fabian Arrotin 28 Jun '22

28 Jun '22

As you're all aware now, CentOS CI infra landscape will be different in the next weeks/months. One of the biggest change will be the introduction of Duffy v3 as replacement for the Duffy API and while there will be compatibility layer (allowing you to use your existing "cico" workflow), the goal is that each tenant will move to the new api, which itself then requires either: - you abusing directly the api endpoint (https://duffy.ci.centos.org/docs) - use the new duffy client (pip3.8 install --user duffy[client] with a config file We'd like to offer the duffy client natively in our cico-workspace pod/container that is automatically deployed for your jenkins jobs on openshift cluster. But if we trigger it, it will also come with something additional : the current centos Stream8 based container is using ansible 2.9.x, which is now deprecated, and kicking a container rebuild would automatically install ansible-core 2.12.x (present in el8 natively now) As you're aware, ansible-core doesn't have all the modules that you probably need to use for your workflow, so instead of install the meta-pkg ansible (which then install almost everything) you can come (reply to this thread) with a list of collections that you'd like to see in the base container (the less we have to pull, the better, to keep the container image as light as possible), we'd then add these to the container image. Thanks for your collaboration, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab

Fedora Rawhide images on the EC2 instances
by František Šumšal 23 Jun '22

23 Jun '22

Hello! After reading & discussing the recent news regarding the move to AWS, I wonder if it would be possible to provide Fedora Rawhide images along with the C8S and C9S ones (and maybe active stable Fedora releases as well). A bit of background: In the systemd project we have several jobs with utilize Vagrant to run an Arch Linux VMs, in which we run tests alongside the C8S/C9S jobs, to cover issues with the latest-ish kernel and other software, and to also hunt down security issues with the latest versions of ASan and UBSan. However, all this is held together by a lot of duct tape and sheer will power, and in the end it requires an EC2 Metal instance to run, due to the additional level of virtualization. If we were able to provision Rawhide instances directly (which should help us achieve the same goal as the Arch Linux VMs we currently use), that could, in theory, allow us to drop the requirement for Metal instances completely. As far as I know, there are Fedora Rawhide AMIs[0], which should make this much easier, but that's all I can say, since I have almost zero experience with AWS overall. Thank you!

reminder : CentOS Linux 8 EOL in december, including for ci test
by Fabian Arrotin 31 Jan '22

31 Jan '22

Just a quick reminder that CentOS Linux 8 is going EOL in december (see https://www.centos.org/centos-linux-eol/) So based on that plan, we'll also remove it from available ci infra at the same time as on mirror network, and if you'll ask for CentOS 8 you'll get no returned node to run your tests on. Start switching your tests to run on 8-stream instead, available since the beginning. -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab

[infra] : Planned outage : CI Openshift/OCP environment
by Fabian Arrotin 18 Jan '22

18 Jan '22

Due to a storage migration (see https://pagure.io/centos-infra/issue/534) we'll have to shutdown and restart the openshift CI cluster (OCP) Migration is scheduled for """"Tuesday January 18th, 9:00 am UTC time"""". You can convert to local time with $(date -d '2022-01-18 09:00 UTC') The expected "downtime" is estimated to ~60 minutes , time needed to : - shutdown openshift workers and control plane nodes - last data sync between old and new nfs storage node - restart openshift control plane and workers nodes Thanks for your comprehending and patience. on behalf of the Infra team, -- -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab

Rebased cico-workspace container in CI openshift available : PLEASE READ
by Fabian Arrotin 02 Dec '21

02 Dec '21

Hi all CI infra tenants/users, As a follow-up wrt previous mail about cico-workspace container update (see https://lists.centos.org/pipermail/ci-users/2021-October/002184.html) we had a look at what was needed to rebase the cico-workspace container to CentOS 8-stream. We've built a container that you can start using with the following specs: - based on centos 8-stream - so having python3 (instead of python2), important for your jobs - still providing python-cicoclient (python3 version) - ansible 2.9.27 - git This container is actually available as staging tag, so it's not *yet* the one that is automatically pulled through your jenkins as "cloud/container" node to run your jobs. We'd like you to start testing your jobs against that updated cico-workspace, at your earliest convenience, so that you have a chance to eventually adapt your jobs, or ask us to add/change something in that container. See the next items # How to test ? The current DeploymentConfig used in openshift will provide jenkins, itself configure to pull cico-workspace from quay.io (quay.io/centosci/cico-workspace:latest) But you can also , as you have full admin rights in your own jenkins namespace, temporary switch to :staging tag. To proceed, just log into your own jenkins apps on openshift/ocp.ci and follow the next steps: Manage Jenkins Manage Nodes and Clouds (under System Configuration) Configure Clouds (on the left menu) Expand Kubernetes and under Pod template you'll see "cico-workspace" "Pod Template details" Containers Just swap quay.io/centosci/cico-workspace:latest => quay.io/centosci/cico-workspace:staging Apply/Save You can now test your job (test job) and see if that still works or if you need to adapt something # How to revert ? Assuming that you want to revert to :latest test (still c7 based), just proceed as above and swap back to quay.io/centosci/cico-workspace:latest #When will you enforce the change ? We have no fixed date in mind but we'd like to enforce this early december, which would give you enough time to fix your jobs (if there is a need to). We can also provide an alternative through a different tag like :c7 while we'd have c8s for :latest and you'd then be also able to modify your jobs to just continue to use older c7 container (not adviced though, but we'll continue to rebuild the container for security updates automatically) Should you have questions/remarks, feel free to chime in ! -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab

CentOS Stream 9 is available in CI infra for tenants/projects
by Fabian Arrotin 25 Oct '21

25 Oct '21

For people not following inititial infra ticket about this (https://pagure.io/centos-infra/issue/441) here is a quick status about CentOS Stream 9 availability in CI infra : Starting from today, each tenant in CI infra can request Stream 9 for the x86_64 architecture. Due to lack of compatible hardware for ppc64le, it's not available yet but we hope to be able to provide it before end of this year. aarch64 is on the list of architectures to be tested and added (more on that when it will be ready) We already updated the python-cicoclient to correct version on the previous Virtual Machines setup behind ci.centos.org but we still have (next on the list) to update the cico-workspace container/image to include newer python-cicoclient (see http://mirror.centos.org/centos/7/infra/x86_64/infra-common/Packages/p/pyth…) that is used in the openshift/ocp 4 cluster Enjoy your tests on Stream 9 ! PS: at the infra side, we'll still have to also have an internal mirror returned by mirrormanager as it's actually using external mirrors, so dnf operations will be "slow" versus what you can see for 7/8/8-stream, but it's on the list -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab

Updated cico-workspace container in OCP cluster
by Fabian Arrotin 21 Oct '21

21 Oct '21

Follow-up on the previous mail about supporting 9-stream in CI infra. We have refreshed the cico-workspace container that is deployed as jenkins agent container and it's available on https://quay.io/repository/centosci/cico-workspace That's the version that is automatically deployed in the OCP cluster. Changes: - updated to CentOS 7.9 + updates - updated python-cicoclient to 0.4.6 (version that supports requesting for '9-stream' nodes to duffy) - added ansible 2.9.27 (per request from some tenants, avoiding to have to install it themselves) Next steps: We'd like to rebase that container to 8-stream in the near future but we'd just need first to have python-cicoclient available as pkg and tested with python3. Once we'll have such test image, we'll rebase and keep you informed about it -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab

[infra] : Planned outage : Jenkins/CI environment
by Fabian Arrotin 28 Sep '21

28 Sep '21

Due to some needed software updates, we'll have to shutdown and restart jenkins on the 'legacy' ci.centos.org setup (reminder : moving to openshift would be great and we'll have to put a hard deadline for this if some tenants are still on the old setup) Migration is scheduled for """"Tuesday September 28th, 9:00 am UTC time"""". You can convert to local time with $(date -d '2021-09-28 09:00 UTC') The expected "downtime" is estimated to ~30 minutes , time needed to put jenkins in "shutdown/quiet mode" , wait for some some jobs to finish, update and restart jenkins. Thanks for your comprehending and patience. on behalf of the Infra team, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab
