Hi everyone,

This is a weekly report from the CPE (Community Platform Engineering) Team. If you have any questions or feedback, please respond to this report or contact us on #redhat-cpe channel on libera.chat (https://libera.chat/).

Week: 6th – 10th 2022

Highlights of the week

Infrastructure & Release Engineering

Goal of this Initiative

Purpose of this team is to take care of day to day business regarding CentOS and Fedora Infrastructure and Fedora release engineering work.
It’s responsible for services running in Fedora and CentOS infrastructure and preparing things for the new Fedora release (mirrors, mass branching, new namespaces etc.).
The ARC (which is a subset of the team) investigates possible initiatives that CPE might take on.

Fedora Infra

  • Staging instance of release-monitoring.org migrated to OCP4 (fixed authentication issue)
  • the-new-hotness 1.2.1 released and deployed on production
  • Got a bunch of f34 machines reinstalled with f36.
  • In the middle of upgrading the wiki (some plugins and theme currently broken in staging)
  • Image builder prod deployment in process, hit some snags with networks
  • Map of critical services is now available in Fedora Infra docs

CentOS Infra including CentOS CI

Release Engineering

  • Fedora 34 is EOL
  • Perl side-tag merged into Fedora 37

CentOS Stream

Goal of this Initiative

This initiative is working on CentOS Stream/Emerging RHEL to make this new distribution a reality. The goal of this initiative is to prepare the ecosystem for the new CentOS Stream.


  • Completed scripting for initial import of module RPMs and module-* tags. Initial importing in progress to c9s koji from c8s koji..
  • Working on automated scripting to pull new builds so that the c9s koji can be automatically updated until we shift to the new koji builder for c8s as well as c9s.

CentOS Duffy CI

Goal of this Initiative

Duffy is a system within CentOS CI infrastructure allowing tenants to provision and access machines (physical and/or virtual, of different architectures and configurations) for the purposes of CI testing. Development of Duffy is largely finished, we’re currently planning and testing deployment scenarios.


  • Release 3.0.1, 3.1.0, 3.2.0 (maybe shouldn’t have skipped betas 🤔).
  • Add client (end user) CLI commands for requesting/retiring/etc. sessions.
  • Add API endpoints and corresponding CLI commands for retrieving information about configured node pools.
  • Fix dependencies to have finer-granular installation options using Python package extras (client CLI, task worker, current and legacy web API servers).

Package Automation (Packit Service)

Goal of this initiative

Automate RPM packaging of infra apps/packages


  • Working on adding packit to datagrepper and noggin
  • Fasjson-client in bugzilla review

Flask-oidc: oauth2client replacement

Goal of this initiative

Flask-oidc is a library used across the Fedora infrastructure and is the client for ipsilon for its authentication. flask-oidc uses oauth2client. This library is now deprecated and no longer maintained. This will need to be replaced with authlib.


  • We now have a very early barebones POC in place which makes use of authlib to authenticate over oidc with Noggin/IPA.
  • Working towards implementing the existing flask-oidc API to retrieve user data.


Goal of this initiative

Extra Packages for Enterprise Linux (or EPEL) is a Fedora Special Interest Group that creates, maintains, and manages a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL), CentOS and Scientific Linux (SL), Oracle Linux (OL).

EPEL packages are usually based on their Fedora counterparts and will never conflict with or replace packages in the base Enterprise Linux distributions. EPEL uses much of the same infrastructure as Fedora, including buildsystem, bugzilla instance, updates manager, mirror manager and more.


  • This week we have 6018 (+155) packages, from 2730 (+58) source packages
  • Unused marketing information and links were removed from EPEL docs
  • Fedora’s backported java_arches macro got merged into epel9

Kindest regards,
CPE Team
