[infra] : Planned outage : RDU2 network maintenance (please read)
by Fabian Arrotin 31 Jan '23

31 Jan '23

Due to a mandatory network maintenance at the RDU2 (Community Cage) facility/DC, we'll have to power off some CentOS infrastructure components hosted in that DC. Impacted services: - https://cbs.centos.org (impossible to submit any build, nor push to delivery network) - https://bugs.centos.org - ns1.centos.org - https://wiki.centos.org - all centos linux / stream 8 / stream 9 release engineering workflow (stream 9 can be built but not pushed out, while for the rest, all will be down) - https://git.centos.org - CI infra: - while openshift in aws is self-contained, there will be no way to request duffy nodes for tests - tenants still on legacy openshift (hosted in that DC) will see the whole cluster being powered down (because of Persistent Volumes hosted in a NFS server that itself will be unavailable) - various other services Migration is scheduled for """"Tuesday January 31th, 1:00 pm UTC time"""". You can convert to local time with $(date -d '2023-01-31 13:00 UTC') The scheduled maintenance window (communicated to us) is estimated to 4h, but we'll restart infra services as soon as possible, following ourselves the current status internally. Thanks for your understanding and patience. on behalf of the Infra team, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | @arrfab[@fosstodon.org]

16 Jan '23

Dear CentOS CI User, Please be advised that the CentOS CI PROD Openshift cluster is due for scheduled maintenance from 12pm to 2pm UTC on Jan 16th. During this period necessary updates will be applied to the cluster, and will be upgraded from version 4.11.18 to 4.11.21 Every service under **apps.ocp.cloud.ci.centos.org <http://apps.ocp.cloud.ci.centos.org>* might be affected. Pods will be restarted, so it's suggested to pause your Jenkins jobs, and there might be periods of slight performance degradation during this maintenance period. We apologise for any inconvenience that this may cause. Kind regards, CentOS CI Infrastructure.

Changes to CentOS CI: New OpenShift instance and Updates
by Camila Granella 02 Jan '23

02 Jan '23

*TL;DR: new OpenShift instance is up and running for CentOS CI, migrate your workloads by March 31st, 2023. Test your access to both the Duffy API and the new OpenShift instance by the end of 2022. CentOS CI changes approaching the end of Phase 3. * Hello everyone, We are happy to announce that the new OpenShift instance is up and running (ticket [0]). For the tenants that opted in to continue using CentOS CI, you are being required to *migrate your workload to the new OpenShift instance by the end of Q1CY23*, with the final deadline being *March 31st, 2023*. In order to support you through the migration process, the team has created a quick guide that can be found in [1]. We would also like to request you test your access to both the Duffy API and the new OpenShift instance by the *end of 2022*. Please reach out to us in case it is not working. Here is the link to the new OCP cluster [2]. As a reminder, this new OCP cluster is running in AWS, on top of EC2 instances, so coming with different limitations when compared with “on-premises bare-metal OCP deployments”. One notable change is that it is not possible to expose /dev/kvm and so there is no way for tenants to deploy VMs through OpenShift (like with the kubevirt operator or else). Tenants having a need to use VMs can then request some through Duffy API. Finally, here's a friendly reminder of the CentOS CI changes' current status. According to our previous communications [3], we are approaching the end of the last phase of the changes that have been implemented to CentOS CI. *Phase 3 - Decommission* - Legacy/compatibility API deprecated and requests (even for EC2 instances) will no longer be accepted - All tenants that opted in will be using only EC2 for aarch64/x86_64 and on-premise cloud for ppc64le For a full description of the project phases, you can check [3]. Please, feel free to reach out to us in case you have any questions or concerns.

Duffy Phase 3 : removing duffy legacy compat api
by Fabian Arrotin 12 Dec '22

12 Dec '22

Hi, As announced in our initial plan (and Camilla sent a reminder last week about that too), we'll just deprecate the internal api endpoint running on duffy (tcp port 8080, mainly for compatibility with the now deprecated cico client). All tenants had enough time (since August) to migrate from old api to new duffy one, as documented on https://sigs.centos.org/guide/ci/#duffy-ephemeral-bare-metalvirtual-machine… So this mail is just a reminder that we'll drop that legacy/compatibility api endpoint today, as announced already Tracking ticket: https://pagure.io/centos-infra/issue/998 Kind Regards, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab

Changes on CentOS CI and next steps
by Camila Granella 02 Dec '22

02 Dec '22

*TL;DR: CentOS CI is going hardwareless and if you wish your project remains using it, we need your opt-in by August 2022. There is a Dojo Summer 2022 <https://wiki.centos.org/Events/Dojo/Summer2022> session happening on Thursday, June 17th, that will explain further technical details. * Hello everyone, As many of you know, since the beginning of this year we have been reevaluating the future of CentOS CI, as currently the hardware being used for it is out of warranty. This is due to the fact that CentOS CI came from community donations of hardware which were maintained in a best effort manner by our team. With no warranties, when the physical machine dies we have no means to replace it. Right now though, our hardware, due to a lack of warranty, will not be moved with the upcoming data center changes due to data center requirements to have in warranty hardware for supportability. We decided to take this opportunity to modernize our current infrastructure, pushing it to a hybrid cloud environment. Duffy CI will become the main tool from now on, so that we can support the CI workflow and best practices on cloud and for this reason, the current hardware infra will no longer be available soon. However, as an effort to continuously provide resources and support CI best practices for projects, our team is adapting Duffy CI so that we can maintain most of the characteristics of our current, physical-based offering. At the technical level, what does that mean for you, CI tenants? - A new Duffy API service will replace the existing one: while it will be running in compatibility/legacy mode with the previous version, you will need to adapt your workflow to the new API, but more details below - We will transition to AWS EC2 instances for the aarch64 and x86_64 architectures by default, with a (limited) option to request “metal” instances for projects requiring virtualization for their tests (like KVM/vagrant/etc) - We will keep a (very small) Power9 infra “on-premise” (AWS does not support ppc64le) for the ppc64le tests (available through a dedicated VPN tunnel) - The existing OpenShift cluster will be also decommissioned and a new one (hosted in AWS, so without an option to run kubevirt operator nor VMs) will be then used (you will have to migrate from one to the other) With that being said, tenants can start preparing for the changes to happen with the maximum deadline of the end of December 2022 wherein at this point, Duffy API legacy mode will be removed. You are required to opt-in if you and/or your team want to use Duffy CI. Projects will only be migrated if they reply to this email confirming that they wish to proceed. Worth knowing that not opting in means that your API key will not be migrated and so all your requests to get temporary/ephemeral nodes will be rejected by the new Duffy API. The maximum decommission deadline of the current hardware infrastructure is December 12th, 2022 and the new Duffy CI will go live in August 2022, so please, complete your migration process by the end of CY22. Reminders of deadlines and of the opt-in requirements will be sent monthly, but your confirmation of opt-in is required by August 2022. When approaching December, reminders about deadlines frequency will increase so that we can ensure effective communication throughout the process. Here are the steps in which we will migrate CI Infra: Phase 1 - Deploy Duffy V3 (August 2022) - Deploy in legacy/compatibility mode, so existing tenants (that opted in !) can still request duffy nodes the same way (like with 'python-cicoclient') : no change at tenants side, and exactly same hardware for tests (transparent migration) - New Duffy API endpoint becomes available, and tenants can start adapting their workflows to point to new API (new ‘duffy-cli’ tool coming, with documentation) - Bare metal and VMs options will be available already through the new API (x86_64, aarch64, ppc64le) Phase 2 - Hybrid Cloud (October 2022) - Legacy/compatibility API endpoint will handover EC2 instances instead of local seamicro nodes (VMs vs bare metal) - Bare metal options will be available through the new API only - Legacy seamicro and aarch64/ThunderX hardware are decommissioned - Only remaining "on-premise" option is ppc64le (local cloud) Phase 3 - Decommission (December 2022) - Legacy/compatibility API deprecated and requests (even for EC2 instances) will no longer be accepted - All tenants that opted in will be using only EC2 for aarch64/x86_64 and on-premise cloud for ppc64le OpenShift new deployment planning and timeline To be defined (deadline for planning and timeline: end of June 2022) Do not hesitate to reach out if you have any questions. It is worth knowing that there will be a dedicated session about the Future of CentOS CI infra at the next CentOS Dojo happening on June 17h (check Dojo Summer 2022 <https://wiki.centos.org/Events/Dojo/Summer2022>). That session will be recorded and then available on Youtube but if you have any questions. Feel free to join the CentOS Dojo and reach out to us!

Disabling dnf execution in background on an EC2 bare metal node
by Anoop C S 28 Nov '22

28 Nov '22

Hi, Post migration to new Duffy API we started noticing the following RPM error intermittently on bare metal nodes reserved from EC2 pool: . . . Running transaction check Waiting for process with pid 2881 to finish. Transaction check succeeded. Running transaction test Transaction test succeeded. Running transaction RPM: error: db5 error(-30969) from dbenv->open: BDB0091 DB_VERSION_MISMATCH: Database environment version mismatch RPM: error: cannot open Packages index using db5 - (-30969) RPM: error: cannot open Packages database in /var/lib/rpm The downloaded packages were saved in cache until the next successful transaction. You can remove cached packages by executing 'dnf clean packages'. Error: Could not run transaction. . . . Especially the "Waiting for process with pid 2881 to finish." indicates some DNF operation in background which may or may not conflict with current DNF execution. With the help of others I got to know about a cloud-init service performing `dnf update` to cope with the very old AMI image with which it is provisioned. Please note that nodes are already marked ready in the pool before `dnf update` kicks in. Therefore I put forward a suggestion to disable `dnf update` as part of cloud-init service such that it does not interfere with other DNF operations done after the node is reserved by a tenant. Please feel free to correct me in any of the details mentioned above and let me know your thoughts. Thanks, Anoop C S.

Changes to CentOS CI: reminder of Phase 3 and update on OpenShift new instance
by Camila Granella 10 Nov '22

10 Nov '22

Hello everyone, This is a friendly reminder of CentOS CI changes' current status and upcoming action items (check [0]) in addition to a quick update on our new OpenShift instance. According to our previous communications [0], we are approaching the last phase of the changes that have been implemented to CentOS CI. We are currently closing phase 2, which began in October. In December, we will move to *phase 3*: *Phase 3 - Decommission* - Legacy/compatibility API deprecated and requests (even for EC2 instances) will no longer be accepted - All tenants that opted in will be using only EC2 for aarch64/x86_64 and on-premise cloud for ppc64le For a full description of the project phases, you can check [0]. Currently, our Infra & Releng team is working to deploy our new OpenShift instance (AWS) in production after some improvements that have been done in staging. When OpenShift gets fully set up, the team will work to migrate the Pagure project. This will then be documented and passed on to you (users) as a guide in order to *facilitate the workload migration that is expected to be done on your side*. We are expecting this to be completed by the end of the year. We will be sharing further information on this at the beginning of Q1CY2023. A reasonable timeline will be provided so that you have enough bandwidth to work on the migration of your workloads. Please, feel free to reach out to us in case you have any questions or concerns.
