Explore a keynote presentation on supporting large-scale and reliability testing in Kubernetes using KWOK (Kubernetes Without Kubelet). Learn about this open-source toolkit that enables the creation and testing of large-scale Kubernetes clusters with minimal resources. Discover how KWOK generates and manages virtual nodes to simulate Kubelet APIs and mimic real nodes, allowing for workload deployment and testing. Gain insights into practical use cases and 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 demonstrations, understand how KWOK can be utilized for reliability testing and evaluating fault-tolerance mechanisms to improve workload resilience in Kubernetes environments.
