Supporting Large-Scale and Reliability Testing in Kubernetes using KWOK

Explore KWOK, an open-source toolkit for creating and testing large-scale Kubernetes clusters with minimal resources. Learn how KWOK generates and manages virtual nodes that simulate Kubelet APIs and mimic real nodes, enabling workload deployment and testing. Discover recent enhancements for reliability and fault-tolerance testing, including the ability to simulate failures by injecting targeted faults into nodes and pods. Through examples and demos, understand how KWOK can be used to improve workload resilience in Kubernetes. Gain insights from KWOK's creator and maintainer, Shiming Zhang, and NVIDIA GPU Cloud engineer Yuan Chen as they discuss practical use cases and demonstrate the toolkit's capabilities for large-scale and reliability testing in Kubernetes environments.
