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.

Quick Start Guide

Prerequisites

• Kubernetes 1.12+ with CRD support

You can try volcano by one the following two ways.

Install with YAML files

Install volcano on a existing Kubernetes cluster.

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.
