This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar. Understand more

KWOK (Kubernetes WithOut Kubelet) is a tool for simulating the lifecycle of fake nodes and pods in order to test the control plane of a Kubernetes cluster. It is difficult to stress test custom Kubernetes controllers and operators without a significantly large cluster. However, with KWOK you can easily set up a cluster with thousands of nodes on your laptop without it consuming a significant amount of CPU or memory. This simulation enables different configurations of node types and pods to test various scenarios and edge cases. If you need a real cluster to test your operators and custom resource definitions (CRDs), we recommend kind or k3s; but if you only need to simulate a large number of fake nodes, then we encourage you to assess KWOK.
