Guiding Kubernetes: The Steering Committee's Role in Project Evolution

The Kubernetes Steering Committee plays a crucial role in overseeing the non-technical aspects of the Kubernetes project and making important project-wide decisions. The committee has a wide scope of working and responsibilities. The committee has evolved over the years. In this session, let’s take a look at how the committee came to be created, the bootstrap era, how it works now and what’s in store for the future. We will have excerpts from our emeritus members who served to shape the goals and vision of the steering committee. We will explore how you can leverage our learnings to enhance the governance of your own cloud native projects. If you are eager to gain insights or have queries about the governance journey of the Kubernetes project, we encourage you to drop by and engage in an insightful discussion

Kubernetes SIG Node Intro and Deep Dive

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!

A Huge Cluster or Multi-Clusters? Identifying the Bottleneck

The increasing complexity of Kubernetes deployments has sparked a debate between scaling single clusters to enormous sizes and managing multiple clusters. At KubeCon NA24, the CNCF Tech Landscape Radar unveiled insights into multicluster application management, while Google showcased a 65000-node cluster powered by Spanner, bypassing etcd's limitations. Similarly, ByteDance has achieved multi-tenancy at scale with Kubebrain.

This talk examines the challenges of large clusters (5,000+ nodes and beyond) and the trade-offs of multicluster solutions. Key topics include API server options, etcd tuning and alternatives (e.g., Kubebrain, kine), and operational concerns such as multi-tenancy models (vCluster, kubezoo, HNC), and operator version control. In parallel, multicluster management solutions like Karmada, Clusternet, and networking challenges with tools like Submariner are explored.

Attendees will gain actionable insights into selecting the most appropriate strategy for their needs.

Deep Dive into Kernel Requirements: strengthening Cloud-Native with new kernel features

- Kubernetes 1.31: Moving cgroup v1 Support into Maintenance Mode: making cgroup v2 (kernel 5.8+) a key requirement.
- Linux Kernel Version Requirements shows kernel requirements of Kubernetes features
- eBPF and Modern Networking and observibility

This talk will provide a detailed look at the kernel version requirements for Kubernetes, with a focus on evolving trends in AI infrastructure, SIG-Node, and SIG-Network. We will explore how different kernel versions influence Kubernetes cluster operations, especially in the areas of network performance, resource management, and security enhancements. This session will also highlight some of the rising star projects in the cloud-native ecosystem, including Cilium, Falco, Pyroscope, Kepler and DeepFlow.

Key Topics:
- AI Infrastructure(device related)
- Kubernetes SIG-Node(cgroup)
- Kubernetes SIG-Network(nftables)
- eBPF-based Projects requirements
- Is kernel version checked enough?
- Dependencies/Ecosystem Maintenance

Kubernetes Community Panel: A Decade of Evolution and Future Trends

Join us in celebrating the 10th anniversary of Kubernetes with a panel featuring some of the community's most influential contributors and maintainers from China. Over the past decade, Kubernetes has grown to the cornerstone of cloud-native infra, thanks to the dedication and innovation of its community members. In this panel, we will talk about our journeys with Kubernetes, share stories and experience, and discuss the future of Kubernetes in the next decade. Our panelists include current and previous owners, tech leads and maintainers. Feel free to join the panel to share your perspectives on the past and next decade of the Kubernetes community and ask anything about the community.

Kubernetes SIG Node Intro and Deep Dive

These are exciting times for Kubernetes SIG Node. Come to our maintainers‘ track session to learn about the just released version 1.28 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 discuss how kubelet handles pod lifecycle including probes and hooks, how node and pod gracefully shutdown as well as many other improvements.

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

How can Pod start-up be accelerated on nodes in large clusters?

The idea came from my recently written blog [Kubernetes 1.27: updates on speeding up Pod startup](https://kubernetes.io/blog/2023/05/15/speed-up-pod-startup/).

This is a common issue that cluster administrators may face.
This session will show you the process of pod startup and everything about how to speed up the startup of pods.

1. API: the creation time of pods by controller-manager, KCM: PV & PVC binding and webhooks.
2. Scheduling: GPU Topology-aware, node load aware
3. Node level from the kubelet side: Image Pulling, Sidecar, API QPS & Burs, Event-Driven PLEG, Throttling, Disk and Volume driver, Static CPU Policy, Container Runtime
4. GPU Management: Topology not only NUMA, Sharing, and Monitoring
5. Data load: data preload & local storage or distributed storage
6. Observability: How to check why the pod starts up slowly?
