Kueue is a set of APIs and controller for job queueing. It is a job-level manager that decides when a job should be admitted to 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 mature functionality in Kubernetes components and well-established third-party controllers. Autoscaling, pod-to-node scheduling and job lifecycle management are the responsibility of cluster-autoscaler, kube-scheduler and kube-controller-manager, respectively. Advanced admission control can be delegated to controllers such as gatekeeper.

- bit.ly/kueue-controller-design presents the detailed design of the controller.
Requires Kubernetes 1.22 or newer.
To install the latest release of Kueue in your cluster, run the following command:
kubectl apply -f https://github.com/kubernetes-sigs/kueue/releases/download/v0.1.0/manifests.yamlThe controller runs in the kueue-system namespace.

A minimal configuration can be set by running the samples:
kubectl apply -f config/samples/single-clusterqueue-setup.yaml
Then you can run a job with:
kubectl create -f config/samples/sample-job.yaml
