Volcano is a Kubernetes-native batch scheduling system, extending and enhancing the capabilities of the standard kube-scheduler. It provides a comprehensive set of features specifically designed to manage and optimize various batch and elastic workloads, including Artificial Intelligence (AI) / machine learning (ML) / deep learning (DL), bioinformatics / genomics, and other "Big Data" applications.
These workloads commonly leverage AI, Big Data, and HPC frameworks such as Spark, Flink, Ray, TensorFlow, PyTorch, Argo, MindSpore, PaddlePaddle, Kubeflow, MPI, Horovod, MXNet, KubeGene, and others, with which Volcano offers robust integration.
Volcano incorporates over fifteen years of collective experience in operating diverse high-performance workloads at scale across multiple systems and platforms. It combines proven best practices and innovative concepts from the open-source community to deliver a powerful and flexible scheduling solution.
As of 2025, Volcano has seen widespread adoption across numerous industries globally, including Internet/Cloud, Finance, Manufacturing, and Medical sectors. Many organizations and institutions are not only end-users but also active contributors to the project. Hundreds of contributors actively participate in code commits, pull request reviews, issue discussions, documentation updates, and design proposals. We encourage your participation in the ongoing development and growth of the Volcano project.
NOTE: the scheduler is built based on kube-batch; refer to #241 and #288 for more detail.
Volcano is an incubating project of the Cloud Native Computing Foundation (CNCF). Please consider joining the CNCF if you are an organization that wants to take an active role in supporting the growth and evolution of the cloud native ecosystem.

- Kubernetes 1.12+ with CRD support
You can try Volcano by one of the following two ways.
Note:
- For Kubernetes v1.17+ use CRDs under config/crd/bases (recommended)
- For Kubernetes versions < v1.16 use CRDs under config/crd/v1beta1 (deprecated)
Install Volcano on an existing Kubernetes cluster. This way is both available for x86_64 and arm64 architecture.
kubectl apply -f https://raw.githubusercontent.com/volcano-sh/volcano/master/installer/volcano-development.yaml
Enjoy! Volcano will create the following resources in volcano-system namespace.

To install official release, please visit helm-charts for details.
helm repo add volcano-sh https://volcano-sh.github.io/helm-charts
helm install volcano volcano-sh/volcano -n volcano-system --create-namespaceInstall from source code for developers:
helm install volcano installer/helm/chart/volcano --namespace volcano-system --create-namespace
# list helm release
helm list -n volcano-systemIf you don't have a kubernetes cluster, try one-click install from code base:
./hack/local-up-volcano.shThis way is only available for x86_64 temporarily.
Please follow the guide Volcano Agent to install volcano agent.
If you want to get prometheus and grafana volcano dashboard after volcano installed, try following commands:
make TAG=latest generate-yaml
kubectl create -f _output/release/volcano-monitoring-latest.yamlPlease follow the guide Volcano Dashboard to install volcano dashboard.
