# Elasticsearch on Container

This document provides step-by-step instructions for installing and configuring **Elasticsearch** within a container-based environment using **Helm**. This setup is designed to work alongside the **OvalEdge application**.

## Prerequisites

**Ensure the following before proceeding:**

* The OvalEdge application must already be deployed.
* Write access to the namespace where OvalEdge is deployed.
* Helm must be installed and properly configured.

## Installation Steps

### **Download Deployment Files**

* **ES-Service.yaml S3 link:**   <https://ovaledge.s3.us-west-1.amazonaws.com/Elasticsearch/es-service.yaml>
* **ES-Deployment.yaml S3 link:**  <https://ovaledge.s3.us-west-1.amazonaws.com/Elasticsearch/es-deployment.yaml>

### **Integrate Deployment Files into Helm Chart**

* Place the downloaded `es-deployment.yaml` and `es-service.yaml` files into the **templates** directory of your existing Helm chart used for OvalEdge deployment.

* Update the `values.yaml` file to include the required **Elasticsearch configuration values** (resource limits, environment variables, volume mounts, etc.).

### **Deploy Elasticsearch**

* Execute the Helm command to deploy Elasticsearch using the updated Helm chart:

  ```bash
  helm upgrade --install ovedge-app ./your-helm-chart-directory --namespace <namespace>
  ```

  👉Replace `<namespace>` with the actual namespace where OvalEdge is deployed.

### **Verify Deployment**

* Verify that Elasticsearch is successfully deployed and accessible from the OvalEdge app pod by running a curl request to the health check endpoint:

  ```bash
  curl http://<dns_or_ip>:9200/health/es/status
  ```

  👉 Replace `<dns_or_ip>` with the actual DNS name or IP address of the deployment environment.

* Ensure that all required ports are open and accessible.
* Validate pod status:

  ```bash
  kubectl get pods -n <namespace>
  ```
* For troubleshooting, check logs:

  ```bash
  kubectl logs <es-pod-name> -n <namespace>
  ```

{% endhint %}

## Conclusion

By following this guide, Elasticsearch will be successfully deployed and integrated within the containerized OvalEdge environment. This setup ensures that Elasticsearch services are properly configured, scalable, and ready to support the application's **search and analytics functions**.
