Get Started

Before reading this guide, we assume you either have a Kubernetes cluster, or a local Kubernetes dev environment, e.g MiniKube. It is also assumed that kubectl is on your path and properly configured. Follow this guide on how to setup a local Kubernetes cluster using docker-desktop.

Install​

The easiest way to get started is to use our Helm Charts to deploy YuniKorn on an existing Kubernetes cluster. It is recommended to use Helm 3 or later versions.

helm repo add yunikorn  https://apache.github.io/incubator-yunikorn-release
helm repo update
kubectl create namespace yunikorn
helm install yunikorn yunikorn/yunikorn --namespace yunikorn

By default, the helm chart will install the scheduler, web-server and the admission-controller in the cluster. When admission-controller is installed, it simply routes all traffic to YuniKorn. That means the resource scheduling is delegated to YuniKorn. You can disable it by setting embedAdmissionController flag to false during the helm install.

If you don't want to use helm charts, you can find our step-by-step tutorial here.

Uninstall​

Run the following command to uninstall YuniKorn:

helm uninstall yunikorn --namespace yunikorn

Access the Web UI​

When the scheduler is deployed, the web UI is also deployed in a container. Port forwarding for the web interface on the standard ports can be turned on via:

kubectl port-forward svc/yunikorn-service 9889:9889 -n yunikorn
kubectl port-forward svc/yunikorn-service 9080:9080 -n yunikorn

9889 is the default port for Web UI, 9080 is the default port of scheduler's Restful service where web UI retrieves info from. Once this is done, web UI will be available at: http://localhost:9889.

YuniKorn UI provides a centralised view for cluster resource capacity, utilization, and all application info.
