Versions:
KWOK, maintained by Kubernetes SIGs, is an open-source cluster-simulation utility designed for developers and testers who need a lightweight yet realistic Kubernetes environment. Version 0.7.0, the fifth public iteration since the project began, allows users to stand up a control plane populated by thousands of virtual Nodes within seconds, eliminating the wait for physical or cloud resources. Each Node is emulated with only negligible CPU and memory overhead, so a complete “cluster” can run comfortably on a single laptop while still exposing the standard kubelet, controller-manager, and scheduler behaviors. This makes KWOK ideal for continuous-integration pipelines that must validate scheduler logic, autoscaling policies, or custom controllers at scale, as well as for classroom or workshop settings where every participant needs an isolated cluster. Because the simulated Nodes report heartbeats, resource capacity, and Pod status exactly as real hardware would, metrics servers, horizontal pod autoscalers, and monitoring dashboards behave identically to production, giving engineers confidence that their tests are meaningful. The toolkit ships as a small Go binary and a set of YAML manifests that can be deployed against any existing kubeconfig; no hypervisors, container runtimes, or cloud credentials are required. KWOK is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
