Hi@akhtar,

You need to download the helm repo to create an Elasticsearch Cluster. You can follow the below-given steps.

• Add Elastic’s Helm repository.

$ Helm repo add elastic https://Helm.elastic.co

• download the Helm configuration for installing a multi-node Elasticsearch cluster on Minikube.

$ curl -O https://raw.githubusercontent.com/elastic/Helm-charts/master/elasticsearch/examples/minikube/values.yaml

• Install the Elasticsearch Helm chart using the configuration you just downloaded.

$ Helm install --name elasticsearch elastic/elasticsearch -f ./values.yaml

==> v1beta1/StatefulSet

NOTES:
1. Watch all cluster members come up.
  $ kubectl get pods --namespace=default -l app=elasticsearch-master -w
2. Test cluster health using Helm test.
  $ Helm test elasticsearch

• last step for deploying Elasticsearch is to set up port forwarding.

$ kubectl port-forward svc/elasticsearch-master 9200
