Kueue

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).

Features overview

• Job management: Support job queueing based on priorities with different strategies: StrictFIFO and BestEffortFIFO.
• Advanced Resource management: Comprising: resource flavor fungibility, Fair Sharing, cohorts and preemption with a variety of policies between different tenants.
• Integrations: Built-in support for popular jobs, e.g. BatchJob, Kubeflow training jobs, RayJob, RayCluster, JobSet, plain Pod and Pod Groups.
• System insight: Built-in prometheus metrics to help monitor the state of the system, and on-demand visibility endpoint for monitoring of pending workloads.
• AdmissionChecks: A mechanism for internal or external components to influence whether a workload can be admitted.
• Advanced autoscaling support: Integration with cluster-autoscaler's provisioningRequest via admissionChecks.
• All-or-nothing with ready Pods: A timeout-based implementation of All-or-nothing scheduling.
• Partial admission and dynamic reclaim: mechanisms to run a job with reduced parallelism, based on available quota, and to release the quota the pods complete.
• Mixing training and inference: Simultaneous management of batch workloads along with serving workloads (such as Deployments or StatefulSets)
• Multi-cluster job dispatching: called MultiKueue, allows to search for capacity and off-load the main cluster.
• Topology-Aware Scheduling: Allows to optimize the Pod-to-Pod communication throughput by scheduling aware of the data-center topology.
• Dynamic Resource Allocation (DRA): Quota management for devices such as GPUs requested through DRA, either with ResourceClaimTemplates or extended resources, including partitionable devices. Consumable capacity is available as an alpha feature.

Production Readiness status

• ✔️ Test coverage:

• ✔️ Scalability verification via performance tests.
• ✔️ Monitoring via metrics.
• ✔️ Security: RBAC based accessibility.
• ✔️ Stable release cycle (2-3 months).
• ✔️ Adopters running on production.

Installation

Officially supported and tested on Kubernetes 1.34 or newer.

To install the latest release of Kueue in your cluster, run the following command:

kubectl apply --server-side -f https://github.com/kubernetes-sigs/kueue/releases/download/v0.20.3/manifests.yaml

The controller runs in the kueue-system namespace.

Read the installation guide to learn more.

Usage

A minimal configuration can be set by running the examples:

kubectl apply -f examples/admin/single-clusterqueue-setup.yaml

Then you can run a job with:

kubectl create -f examples/jobs/sample-job.yaml
