Add Single-sign-on To Your Applications With Keycloak and Learn About Its Latest Features - Takashi Norimatsu, Hitachi & Marek Posolda, Red Hat

Monday June 16, 2025 12:10 - 12:40 JST

Level 1 | Appollon

Keycloak is an Identity and Access Management (IAM) open-source software, and CNCF incubating project.
Use it to add single-sign-on and authentication to your applications and secure your services with minimum effort.

In the first part of this talk, we will introduce Keycloak and tell what Keycloak can do, how you can use Keycloak, where Keycloak is used and how Keycloak can resolve the issue that developers encounter when using IAM. We'll look behind the scenes how Keycloak is managed by maintainers, how you can contribute to Keycloak, which community activities are going on, and how you can participate in the activities.

In the second part of this talk, we will explain the latest updates of Keycloak and introduce new features, enhancements of existing features. We will also describe planned features and enhancements for the future.

KubeVirt Community: Let's Talk Multiarch Support! - Howard Zhang, Arm

Monday June 16, 2025 14:10 - 14:40 JST

Level 1 | Appollon

Last year we formalised two architecture Working Groups: S390x and ARM. Come and hear about how these important works are going from one of the WG chairs. You'll learn about ARM's plan for CDI support, IBM's contributions to run CDI on s390x architecture, and the KubeVirt community's progress in supporting CDI in multi-arch cluster environments.

We'll also provide a short community update about how these working groups are part of the KubeVirt community formalising its SIG structure, itself part of a larger maturation process that started with slowing our release cadence and also encapsulates changes to our design proposal (VEPs) process, feature prioritization, and our governance.

Kubernetes SIG Node Intro and Deep Dive - Narang Dixita Sohanlal, Google; Paco Xu, DaoCloud; Hironori Shiina, Independent

Monday June 16, 2025 14:50 - 15:20 JST

Level 1 | Appollon

These are exciting times for Kubernetes SIG Node. Come to our maintainers‘ track session to learn about the just released version 1.34 of Kubernetes, full of exciting improvements, and get a glance into the SIG Node roadmap. SIG Node owns components that control interactions between pods and host resources, including the Kubelet, Container Runtime Interface (CRI), and Node API. SIG Node is responsible for the Pod’s lifecycle from allocation to teardown, to liveness checks and shared resource management. We work with the various container runtimes, kernels, networking, storage, and more; anything a pod touches is SIG Node’s responsibility!

We will make a deep dive into the area of pod lifecycle starting with developments like evented PLEG as well as well established things like probes and handling the resource management when pod scaling.

Join this session to learn more about our SIG, and how you might get involved to make Node even better!

Longhorn: Intro, Deep Dive and Q&A - Derek Su, SUSE

Monday June 16, 2025 15:50 - 16:20 JST

Level 1 | Appollon

Longhorn is a widely adopted cloud-native storage solution with hundreds of thousands of installations in community and production environments. It supports various volume and access modes, CoW snapshots for space efficiency, and seamless CSI integration. Designed for enterprise readiness, it also offers out-of-cluster incremental backups for disaster recovery.

This talk covers Longhorn’s architecture, key features, community adoption, recent updates, and roadmap. We’ll also explore the V2 Data Engine—its next-generation storage backend—leveraging NVMe and ublk for high performance. Live demos will showcase how Longhorn maximizes volume capacity and efficiency with this new engine.

Prometheus 3.0 and the New Governance: Setting the Project up for the Next Decade - Josue Abreu, Grafana Labs

Monday June 16, 2025 16:30 - 17:00 JST

Level 1 | Appollon

Prometheus joined the CNCF as its second project in 2016, nearly a decade ago. Ever since, Prometheus has the cloud native default for monitoring, and everyone using Kubernetes successfully is using Prometheus in some way or form.

We will give a short intro to Prometheus, it's strengths and top usecases.

We will also dive into the Prometheus 3.0 release, the new governance structure, and the roadmap for the next year. We will share how you can get involved and become a maintainer yourself.

Sailing Multi-host Inference for LLM on Kubernetes - Kay Yan, DaoCloud

Monday June 16, 2025 17:10 - 17:40 JST

Level 1 | Appollon

Inference workloads are becoming increasingly prevalent and vital in Cloud Native world. However, it's not easy, one of the biggest challenges is large foundation model can not fit into a single node, such as llama3.1-405B or DeepSeek R1, which brings out the distributed inference with model parallelism, again, make serving inference workloads more complicated.

LeaderWorkerSet, aka. LWS, is a dedicated multi-host inference project aims to solve this problem, it's a project under the guidance of Kubernetes SIG-Apps and Serving Working Group. It offers a couple of features like dual-template for different types of Pods, fine-gained rolling update strategies, topology managements and all-or-nothing failure handlings.

What's more, vLLM, an inference engine, renowned for its performance and easy-to-use, has gained widespread popularity. In this presentation, we'll show you how to use LWS to deploy distributed inference with vLLM on Kubernetes.
