# OpenEBS can be setup in few easy steps.
# You can get going on your choice of Kubernetes cluster by having open-iscsi installed on the Kubernetes nodes and running the openebs-operator using kubectl.
# Start the OpenEBS Services using Operator:
$ kubectl apply -f https://raw.githubusercontent.com/openebs/openebs/master/k8s/openebs-operator.yaml
# As an alternative to the above comment you can also use Helm package manager to install OpenEBS.

$ helm install stable/openebs
