Scheduler Testing with KWOK #

This document walks you through the technical outcome of using KWOK for scheduler tests.

KWOK can be used to create fake nodes and pods in a simulated cluster. The cluster can be configured with scheduling policies that meet your scheduler’s requirements. The scenarios below can be used to describe this:

• Scheduling pods with resource requests and limits
• Scheduling a pod to a particular node with node-affinity
• Scheduling pods with taints and tolerations
• Scheduling pods with a limit range
• Scheduling pods using pod priority and preemption
• Scheduling pods using pod topology spread constraints

Other scheduling scenarios can also be simulated using KWOK.
