Volcano is a batch system built on Kubernetes. It provides a suite of mechanisms that are commonly required by many classes of batch & elastic workload including: machine learning/deep learning, bioinformatics/genomics and other "big data" applications. These types of applications typically run on generalized domain frameworks like TensorFlow, Spark, PyTorch, MPI, etc, which Volcano integrates with.
Volcano builds upon a decade and a half of experience running a wide variety of high performance workloads at scale using several systems and platforms, combined with best-of-breed ideas and practices from the open source community.
NOTE: the scheduler is built based on kube-batch; refer to #241 and #288 for more detail.
Volcano is a sandbox 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 v1.16+ 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.
For x86_64:
kubectl apply -f https://raw.githubusercontent.com/volcano-sh/volcano/master/installer/volcano-development.yaml
For arm64:
kubectl apply -f https://raw.githubusercontent.com/volcano-sh/volcano/master/installer/volcano-development-arm64.yaml
Enjoy! Volcano will create the following resources in volcano-system namespace.

If 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.
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.yamlRegular Community Meeting:
The Volcano team meets once per week on Friday, alternating between 10am Beijing Time (Convert to your timezone.) and 3pm Beijing Time (Convert to your timezone.)
