Build Status Go Report Card RepoSize Release LICENSE CII Best Practices

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, Ray, 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.

Until June 2021, Volcano has been widely used around the world at a variety of industries such as Internet/Cloud/Finance/ Manufacturing/Medical. More than 20 companies or institutions are not only end users but also active contributors. Hundreds of contributors are taking active part in the code commit/PR review/issue discussion/docs update and design provision. We are looking forward to your participation.

NOTE: the scheduler is built based on kube-batch; refer to #241 and #288 for more detail.

Quick Start Guide

Prerequisites

  • 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 with YAML files

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.

Install via helm

To install official release, please visit to 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-namespace

Install from source code for developers:

helm install volcano installer/helm/chart/volcano --namespace volcano-system --create-namespace

# list helm release
helm list -n volcano-system

Install from code

If you don't have a kubernetes cluster, try one-click install from code base:

./hack/local-up-volcano.sh

This way is only available for x86_64 temporarily.

Install monitoring system

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.yaml
