The record

Purpose: KWOK simulates Kubernetes nodes, pods, and other API resources so users can set up clusters of thousands of nodes in seconds.
Tools: The project provides `kwok` to simulate resource lifecycles and `kwokctl` to create and manage clusters.
Scale: The project says KWOK can reliably maintain 1,000 nodes and 100,000 pods.
Performance: The project says KWOK can create 20 nodes or pods per second.
Configuration: Users can configure node types, labels, taints, capacities, conditions, and pod behaviors to test scenarios and edge cases.
Kubernetes compatibility: KWOK works with Kubernetes API-compliant tools and clients, including kubectl, Helm, and Kui.
Integrations: The documentation includes integration examples for Argo, Istio, Kueue, Linkerd, Prometheus, Metrics Server, and Ray.
Metrics: KWOK documents enabling Prometheus for a cluster and using Prometheus as a Grafana data source.
Installation: The project documents installation through Homebrew, WinGet, Go, and downloadable binaries.
Platforms: The runtime support matrix covers Linux, macOS (Darwin), and Windows on amd64 and arm64, with support varying by runtime and architecture.
Limitation: KWOK simulates pods rather than running them, so a pod in a KWOK cluster does not perform real workload behavior such as serving an HTTP response.
Security and license: The source repository identifies the project as Apache-2.0 licensed and links to a security policy.
Community support: Users can reach the maintainers through GitHub issues and discussions or the Kubernetes #kwok and #kwok-dev Slack channels.
Known issue: With AWS, GCP, or Azure cloud-provider integrations, nodes may be unexpectedly deleted if they lack provider IDs; the documentation recommends assigning a dummy providerID.
