volcano/volcano
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:
- machine learning/deep learning,
- bioinformatics/genomics, and
- other “big data” applications.
Introduction
This chart bootstraps volcano components like controller, scheduler and admission controller deployments using Helm package manager.
Prerequisites
- Kubernetes 1.13+ with CRD support
Installing Chart
To install the chart with the release name volcano-release:
$ helm repo add volcano-sh https://volcano-sh.github.io/charts
$ helm install --name volcano-release volcano-sh/volcano
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-controllers |
basic.scheduler_image_name |
Scheduler Docker Image Name | volcanosh/vc-scheduler |
basic.admission_image_name |
Admission Controller Image Name | volcanosh/vc-admission |
basic.admission_secret_name |
Volcano Admission Secret Name | volcano-admission-secret |
basic.scheduler_config_file |
Configuration File name for Scheduler | kube-batch.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
