Volcano

Volcano is a batch system built on Kubernetes. It provides a suite of mechanisms currently missing from
Kubernetes that are commonly required by many classes of batch & elastic workload including:

1. machine learning/deep learning,
2. bioinformatics/genomics, and
3. other "big data" applications.

Prerequisites

• Kubernetes 1.12+ with CRD support

Installing volcano via yaml file

All-in-one yaml has been generated for quick deployment. Try command:

kubectl apply -f volcano-v0.0.x.yaml

Check the status in namespace volcano-system

$kubectl get all -n volcano-system

Installing volcano via helm charts

To install the volcano with chart:

helm install helm/chart/volcano --namespace <namespace> --name <specified-name>

e.g :
helm install helm/chart/volcano --namespace volcano-trial --name volcano-trial

This command deploys volcano in kubernetes cluster with default configuration. The configuration section lists the parameters that can be configured during installation.

Uninstalling the Chart

$ helm delete volcano-release --purge

Configuration

The following are the list configurable parameters of Volcano Chart and their default values.

Parameter	Description	Default Value
basic.image_tag_version	Docker image version Tag	latest
basic.controller_image_name	Controller Docker Image Name	volcanosh/vc-controller-manager
basic.scheduler_image_name	Scheduler Docker Image Name	volcanosh/vc-scheduler
basic.admission_image_name	Admission Controller Image Name	volcanosh/vc-webhook-manager
basic.admission_secret_name	Volcano Admission Secret Name	volcano-admission-secret
basic.scheduler_config_file	Configuration File name for Scheduler	config/volcano-scheduler.conf
basic.image_pull_secret	Image Pull Secret	""
basic.image_pull_policy	Image Pull Policy	IfNotPresent
basic.admission_app_name	Admission Controller App Name	volcano-admission
basic.controller_app_name	Controller App Name	volcano-controller
basic.scheduler_app_name	Scheduler App Name	volcano-scheduler

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install --name volcano-release --set basic.image_pull_policy=Always volcano/volcano

The above command set image pull policy to Always, so docker image will be pulled each time.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

$ helm install --name volcano-release -f values.yaml volcano/volcano

Tip: You can use the default values.yaml
