+ <p>CentOS Stream is a Linux distribution built by Red Hat Enterprise Linux (RHEL)
|
| |
+ engineers as part of RHEL development.</p>
|
| |
+ <p>Innovation within the OS happens in Fedora.
|
| |
+ CentOS Stream provides a solid base for innovation on top of an OS.
|
| |
+ Many CentOS Special Interest Groups (SIGs) are building on and extending it in all
|
| |
+ sorts of interesting ways without needing to reinvent the wheel.</p>
|
| |
+ <p>CentOS Stream also serves as a contribution path to RHEL itself.
|
| |
+ The source, the builds, the release, it all happens in the open.</p>
|
| |
+ <p>Come and learn about what's new, what's coming,
|
| |
+ how to get involved both directly and through CentOS SIGs.</p>

|

|
| |
+ <p>This session highlights the OKD community’s initiative to evolve
|
| |
+ Kubernetes scheduling into a dynamic, collaborative framework.
|
| |
+ Building on the experience gained from developing the Multiarch
|
| |
+ Tuning Operator for OpenShift, the initiative leverages Kubernetes'
|
| |
+ 2scheduling gates mechanism to go beyond multi-architecture-aware scheduling.
|
| |
+ It introduces a framework where multiple controllers can compete to inject
|
| |
+ augmented information into pod specifications, enabling smarter and more
|
| |
+ efficient pod placement across Kubernetes clusters.</p>
|
| |
+ <p>Rooted in OKD, the upstream distribution of OpenShift, and running on
|
| |
+ CentOS Stream CoreOS, this effort showcases how the OKD community is driving
|
| |
+ innovation for scheduling in Kubernetes Clusters.
|
| |
+ The framework optimizes workload placement while coordinating with
|
| |
+ descheduling and autoscaling components.</p>
|
| |
+ <p>This talk will explore how OKD’s community-driven approach connects
|
| |
+ observability platforms with Kubernetes’ scheduling ecosystem, closing
|
| |
+ the feedback loop for improved performance, SLA guarantees, cost savings,
|
| |
+ and energy efficiency.
|
| |
+ Attendees will also learn how this framework lays the foundation for a fully
|
| |
+ distributed, intelligent placement system for Kubernetes workloads.</p>
|
| |
+ <p>Join us to discover how the OKD community is extending its vision through
|
| |
+ CentOS Stream CoreOS, fostering collaboration and innovation to advance
|
| |
+ Kubernetes scheduling.</p>

|

|
| |
+ There was a lot of frantic scrambling among the Artwork, Infra, Docs,
|
| |
+ and Promo SIGs. There were snags. There were delays.
|
| |
+ But we finally got it out the door.</p>
|
| |
+ <p>This talk will explore what we did.
|
| |
+ But more importantly, it will explore what we didn't do.
|
| |
+ We had to think hard about what work we could defer to meet deadlines.

|
| |
+ This initiative is conducted alongside the Konflux effort which is taking

|
| |
+ <p>On the dates of CentOS Connect 2025, we get to celebrate exactly 4 years
|
| |
+ since the release of the very first beta version of AlmaLinux.
|
| |
+ While being RHEL (and later CentOS Stream) derivative AlmaLinux still does
|
| |
+ a lot of things differently both on the distribution and tooling sides.
|
| |
+ Our build system and mirror service are just the tip of the iceberg.
|
| |
+ In my talk I'd like to focus on more things we do differently, like:</p>
|
| |
+ <ul><li>How we build images</li>
|
| |
+ <li>How we produce errata</li>
|
| |
+ <li>How we do OpenSCAP profiles and OVAL data</li>
|
| |
+ <li>How we support additional hardware and older CPUs</li>
|
| |
+ <li>How we extend virtualization support</li></ul>
|
| |
+ <p>... and many more.</p>
|
| |
+ <p>This can be useful for users and developers to look at familiar
|
| |
+ features and processes from a new angle.</p>

|
| |
+ <p>What if detecting bugs and vulnerabilities in RPM-based
|
| |
+ distributions could be seamless and fully automated?</p>
|
| |
+ <p>OpenScanHub is a service for static and dynamic code analysis.
|
| |
+ It was internally used inside Red Hat to scan releases of RHEL
|
| |
+ for more than a decade and was open-sourced in 2023.</p>
|
| |
+ <p>OpenScanHub can fully automatically scan RPMs and has the ability
|
| |
+ to do differential scans that helps in finding bugs that may be
|
| |
+ introduced on package updates and new distribution releases.
|
| |
+ By default, it supports static analyzers embedded in GCC, Cppcheck, ShellCheck,
|
| |
+ find-unicode-control, Clippy and is extensible to support other analyzers.
|
| |
+ It can collect reports from various analyzers at a single place to
|
| |
+ make it easy to analyze them.</p>
|
| |
+ <p>OpenScanHub was recently integrated with Packit, a CI/CD solution for
|
| |
+ automating RPM package builds, tests, and distribution releases.
|
| |
+ This new integration performs differential scans on pull requests,
|
| |
+ so potential bugs may be found during the pull request review process
|
| |
+ and would not be introduced into the codebase.</p>
|
| |
+ <p>In this talk, we will share ideas about how CentOS Stream and its
|
| |
+ derivatives may benefit from OpenScanHub.</p>

+ Fedora EPEL, and our own produced packages.
|
| |
+ This gives us a broad content set, but since each of these are released
|
| |
+ with their own cadences, it becomes important to create discrete collections
|
| |
+ of this for various purposes (notably integration testing).</p>

|
| |
+ Specifically for CentOS SIGs this time.</p>
|
| |
+ <p>Providing builds and CI for your SIG is not easy, and with Packit,
|
| |
+ we thought we could be of help.
|
| |
+ We were asked about this a long long time ago, but last year,
|
| |
+ Christian Glombek sent us the first contribution that kicked off the
|
| |
+ actual work and together with the Packit team, the work on automation
|
| |
+ for CBS Koji builds started for real.
|
| |
+ Just another Koji instance one would say.
|
| |
+ We’ve come a long way since then and learned our lesson.
|
| |
+ Come and see what it takes to automate RPM builds on CBS Koji in
|
| |
+ reality and how you can benefit from our work.</p>

|
| |
+ community maintained packages for use on CentOS Stream and Red Hat
|
| |
+ Enterprise Linux (RHEL).
|
| |
+ For most of its history, each version of EPEL was made available after
|
| |
+ the corresponding major version of RHEL.
|
| |
+ This slowed down package availability, which then slowed down adoption
|
| |
+ of new RHEL major versions.
|
| |
+ In EPEL 9, package maintainers were able to build against CentOS Stream 9
|
| |
+ early to have a large number of packages ready before the RHEL 9.0 launch.</p>
|
| |
+ <p>For EPEL 10, the EPEL Steering Committee is expanding that strategy
|
| |
+ to all minor versions of RHEL 10.
|
| |
+ This will improve support for CentOS Stream and for specific minor versions
|
| |

|

+ This is a follow-up to previous CentOS Connect talks, discussing how
|
| |
+ I am using poi-tracker to track packages, export them to ELN Extras
|
| |
+ workloads, and then use ebranch to branch and build these packages
|
| |
+ and their dependencies in EPEL 10.
|

+ However, for AI/ML workloads which require a complicated stack of dependencies,
