Kueue is a set of APIs and controller for job queueing. It is a job-level manager that decides when a job should start (as in pods can be created) and when it should stop (as in active pods should be deleted). The main design principle for Kueue is to avoid duplicating existing functionality: autoscaling, pod-to-node scheduling, job lifecycle management and advanced admission control are the responsibility of core k8s components or commonly accepted frameworks, namely cluster-autoscaler, kube-scheduler and kube-controller-manager and gatekeeper, respectively.
bit.ly/kueue-apis (please join the mailing list to get access) discusses the API proposal and a high-level description of how it operates; while bit.ly/kueue-controller-design presents the detailed design of the controller.
Requires k8s 1.22 or newer
You can run Kueue with the following command:
IMAGE_REGISTRY=registry.example.com/my-user make image-build image-push deployThe controller will run in the kueue-system namespace.
Then, you can and apply some of the samples:
kubectl apply -f config/samples/minimal.yaml
kubectl create -f config/samples/sample-job.yaml
