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
3. other "big data" applications.
These types of applications typically run on generalized domain
frameworks like TensorFlow, Spark, PyTorch, MPI, etc, which Volcano integrates with.
Some examples of the mechanisms and features that Volcano adds to Kubernetes are:
1. Job management extensions and improvements, e.g:
1. Multi-pod jobs
2. Lifecycle management extensions including suspend/resume and
restart.
3. Improved error handling
4. Indexed jobs
5. Task dependencies
2. Scheduling extensions, e.g:
1. Co-scheduling
2. Fair-share scheduling
3. Queue scheduling
4. Preemption and reclaims
5. Reservations and backfills
6. Topology-based scheduling
3. Runtime extensions, e.g:
1. Support for specialized container runtimes like Singularity,
with GPU accelerator extensions and enhanced security features.
4. Other
1. Data locality awareness and intelligent scheduling
2. Optimizations for data throughput, round-trip latency, etc.
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](https://github.com/kubernetes-sigs/kube-batch);
refer to [#241](https://github.com/volcano-sh/volcano/issues/241) and [#288](https://github.com/volcano-sh/volcano/pull/288) for more detail.
You can watch industry experts talking about Volcano in different International Conferences over [here.](https://volcano.sh/talk/)
The easiest way to deploy Volcano is to use the Helm chart. Volcano can be deployed by cloning code and also by adding helm repo.
Add helm repo using following command,
```
helm repo add volcano https://volcano-sh.github.io/charts
```
Install Volcano using following command,
```
helm install volcano/volcano --namespace <namespace> --name <specified-name>
e.g :
helm install volcano/volcano --namespace volcano-trial --name volcano-trial
```
First of all, clone the repo to your local path:
```
```
Official images are available on [DockerHub](https://hub.docker.com/u/volcanosh), however you can
build them locally with the command:
```
cd $GOPATH/src/volcano.sh/volcano
make images
REPOSITORY TAG IMAGE ID CREATED SIZE
volcanosh/vc-admission latest a83338506638 8 seconds ago 41.4MB
volcanosh/vc-scheduler latest faa3c2a25ac3 9 seconds ago 49.6MB
volcanosh/vc-controllers latest 7b11606ebfb8 10 seconds ago 44.2MB
```
**NOTE**:
1. You need ensure the images are correctly loaded in your kubernetes cluster, for
example, if you are using [kind cluster](https://github.com/kubernetes-sigs/kind),
try command ```kind load docker-image <image-name>:<tag> ``` for each of the images.
2. When reinstall the volcano charts, since tiller server will not manage CRD resource,
you need to delete them manually eg: `kubectl delete crds xxxx` before reinstalling or try command with `--no-crd-hook` option.
Secondly, install helm chart.
```
helm install installer/helm/chart/volcano --namespace <namespace> --name <specified-name>
e.g :
helm install installer/helm/chart/volcano --namespace volcano-trial --name volcano-trial
```
To verify your installation run the following commands:
```
NAME READY STATUS RESTARTS AGE
<specified-name>-admission-84fd9b9dd8-9trxn 1/1 Running 0 43s
<specified-name>-controllers-75dcc8ff89-42v6r 1/1 Running 0 43s
<specified-name>-scheduler-b94cdb867-89pm2 1/1 Running 0 43s
<specified-name>--admission-init-qbtmb 0/1 Completed 0 43s
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
<specified-name>-admission-service ClusterIP 10.105.78.53 <none> 443/TCP 91s
