## Install OpenSearch using Helm
## Prerequisites
1. Clone the [Helm/opensearch](https://github.com/opensearch-project/opensearch-devops/) repository:
Before you get started, you must first use [Helm to install OpenSearch]({{site.url}}{{site.baseurl}}/opensearch/install/helm/).
```bash
git clone https://github.com/opensearch-project/opensearch-devops.git
```
Make sure that you can send requests to your OpenSearch pod:
1. Change to the `opensearch` directory:
```bash
cd Helm/opensearch
```
1. Package the Helm chart:
```bash
helm package .
```
1. Deploy Elasticsearch:
```bash
helm install --generate-name opensearch-1.0.0.tgz
```
The output shows you the specifications instantiated from the install.
To customize the deployment, pass in the values that you want to override with a custom YAML file:
```bash
helm install --values=customvalues.yaml opensearch-1.0.0.tgz
```
#### Sample output
```yaml
NAME: opensearch-1-1628710514

NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
Watch all cluster members come up.
```
To make sure your Elasticsearch pod is up and running, run the following command:
```bash
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
opensearch-cluster-master-0 0/1 ContainerCreating 0 34s
opensearch-cluster-master-1 0/1 ContainerCreating 0 34s
opensearch-cluster-master-2 0/1 ContainerCreating 0 34s
```
To access the Elasticsearch shell:
```bash
$ kubectl exec -it opensearch-cluster-master-0 -- /bin/bash
```
You can send requests to the pod to verify that Elasticsearch is up and running:
```bash
```json
$ curl -XGET https://localhost:9200 -u 'admin:admin' --insecure

## Install OpenSearch Dashboards using Helm
1. Clone the [Helm/opensearch-dashboards](https://github.com/opensearch-project/opensearch-devops/tree/main/Helm/opensearch) repository:
```bash

## Prerequisites
The default Helm chart deploys a 3-node cluster. We recommend that you have 8 GiB of memory available for this deployment. You can expect the deployment to fail if, say, you have less than 4 GiB of memory available.
