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.

Sailing Multi-host Inference for LLM on Kubernetes - Kante Yin, DaoCloud

Monday June 16, 2025 17:15 - 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.
