Sessions
+ +Offered CentOS Infra services for SIGs
+ +In this talk, we'll do a quick recap about which kind of services (from git + hosting to building and cdn delivery, as well as CI testing) the CentOS Infra + team is offering and maintaining for the Special Interest Groups
+MirrorManager and CentOS Stream 9
+ +Fedora relies on MirrorManager since 2008 and with CentOS Stream 9 CentOS + mirrors are now also managed by the MirrorManager instance.
+For the CentOS community I want to use this session to give an overview how + MirrorManager works. I want to give an introduction about all the different + parts that are necessary to make MirrorManager work as well as how the Fedora + instance is set up. I also want to highlight how MirrorManager differs from + the traditional CentOS mirror infrastructure.
+In addition to the introduction for the CentOS community I also want to present + what has changed in the last 6 years and how and why we rewrote core components + in Rust.
+One year on: Experiences using ebranch to bring over Fedora packages to EPEL
+ +At this event last year, I described a WIP tool called ebranch + (https://pagure.io/epel/ebranch) that is meant to simplify the workflow + of branching a specific package for an EPEL release, together with all the + missing dependencies needed to build it.
+One year on, this tool has been used for bringing over various sets of new + packages to EPEL, in different programming language stacks (from Python to + Perl to Rust); this talk discusses the current state of the tool, how features + are added to address specific needs, the experiences gained in writing and + using the tool, and the pros and cons of how different language stacks are + managed in Fedora when it comes to branching to EPEL.
+Hyperscale SIG update
+ +Update on what the Hyperscale SIG has been working on, what deliverables + are available and how to use them, and what's coming up next.
+Introducing CentOS Stream CoreOS and OKD Streams
+Christian Glombek and Alessandro Di Stefano
+CentOS Stream CoreOS (SCOS) is a Linux distribution built from CentOS + Stream RPM packages, and focused on running container-based workloads + with Kubernetes. It is part of the SCOS Stream of OKD, the Kubernetes + community distribution of OpenShift, co-maintained by the CentOS Cloud + SIG and the OKD Working Group.
+In this presentation, we'll present the technologies and methodologies + driving the CentOS Stream CoreOS (SCOS) release engineering, and the + Cloud-Native architecture we leverage to package the operating system + that runs Kubernetes/OKD.
+We'll show how this framework, powered by Tekton pipelines and operated + via GitOps, can enable, thanks to rpm-ostree, the CoreOS Assembler and the + Layering model, delivery scenarios for different OSes beyond the Cloud-Native + ones: IoT, multimedia, automotive, thin-client-based environments. Users can + derive their own purpose-driven variants by maintaining a common multi-arch + base OS, distributed as a bootable Open Container Image (OCI).
+CentOS Stream: RHEL development in public
+ +CentOS Stream is where RHEL development happens in public. You can preview + content coming to RHEL, test your things on top of it, and even participate! + We'll show you how it works, highlight the key differences between Fedora ELN, + CentOS Stream and RHEL, and see where it's all happening.
+Kmods SIG Update
+ +Update on what the Kmods SIG has been working on with a particular emphasis + on automation of rebuilding kABI tracking kernel modules if required.
+Network management in Enterprise Linux: present and future
+ +The talk will explore the current state of network management in Enterprise + Linux systems and discuss potential future developments in the field. The + presentation will cover topics such as network configuration and troubleshooting, + with a focus on the NetworkManager and Nmstate tools. The aim of the talk is to + provide a comprehensive overview of network management in Enterprise Linux and + to discuss the challenges and opportunities that lie ahead for enterprise Linux + users.
+Introduction to Rocky Linux and Peridot: Maintaining a downstream fork of Red Hat Enterprise Linux
+ +Learn about Peridot, a new open source build system created and used by + Rocky Linux to simplify the process of maintaining a downstream fork of + Red Hat Enterprise Linux. Discover how Peridot can be used to patch and + rebuild RPMs, modify upstream RPMs, or package your own software, and how + Rocky Linux uses it to manage the rebuilding of all packages in Enterprise + Linux and help drive upstream contributions while enabling Rocky's unique + special interests. This presentation is ideal for users of RHEL-like + operating systems who want to improve their Linux deployment and management + processes. Join us to learn about the benefits of Peridot and Rocky Linux + and how you can use them to optimize your Linux system and streamline your + development workflow.
+From code to cloud - the journey of Openstack package
+ +OpenStack is a huge cloud computing project, which does not provide + packaging for platforms – RDO does it for rpm-based Linux distros. + Delivering packages for such project with new release every half a + year is a challenging task. In this talk I’d like to bring closer to + audience our continous-delivery approach to package delivery – starting + from creating and adding new packages, through updates and managing all + packages already delivered, share our practice in automation and tips + how to not get drown in dependencies of dependencies. The journey will + also have quick stop in building tools we are using in RDO and continuous + integration to ensure stability and compatibility, to finally reach the + point of having new OpenStack release. This talk is intended not only for + those, whose daily duties are connected with cloud or continous-delivery + technologies, but also for anyone interested in topic of delivering + packages at great scale in open source cloud project, or would like to + contribute to RDO.
+A year in review 2023 - CentOS Automotive SIG
+ +A review of what's going on in our CentOS Automotive SIG, our AutoSD + image, how to run an AutoSD VM to try AutoSD, PREEMPT_RT kernel. Similar + in ilk to "Fedora: The Vehicle for Automotive Linux" presented by Stephen + Smoogen and Allison King at "Nest with Fedora 2022".
+Running Cloud Native Applications on CentOS on a Cloud Native Processor; Setting up and running a Mastodon Server on Arm servers in the cloud
+ +In recent months, Mastodon has garnered a lot of attention, and seen a huge + influx of new users. Mastodon is a social network built on ActivityPub, a + protocol for federated social media. In early December, the network broke 8 + million users, and had 2.5M active daily users in one week.
+That influx of new users and interest has led to many new Mastodon instances + being added, some with a very broad appeal, and others targeting smaller + groups and niche interests. It has also led to some of the more popular + instances of Mastodon struggling to scale with the new demand.
+In this talk, we will walk you through how Mastodon’s federated architecture + is designed for the cloud and how easy Mastodon is to set up and run on a + CentOS instance on AArch64 cloud instances for free. And since Mastodon’s + backend is written in Ruby on Rails, using Redis and PostgreSQL, we will + show how easily they run on an AArch64 processor.
+In addition, we will look at how well the Ampere Altra processor handles + cloud native workloads on CentOS. We will show you not only how to run + Mastodon on AArch64, but how to do it for free, without having to worry + about getting a large cloud bill. Recent events at Twitter gave us the + fun idea of how to combine all of this: create and run a Mastodon server + on Oracle Cloud’s (OCI) Always Free tier using Ampere A1 and CentOS.
+We will also talk about some of the scaling issues that Mastodon runs + into, and how Ampere cores designed for cloud native workloads like + Mastodon are uniquely able to give you predictable throughput and + scaling as your server grows in popularity. All while doing this on a + processor that is more efficient (i.e. greener) than other processors + out there.
