Elasticsearch Single-Node Search and Analytics

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

## Elasticsearch AMI - Supported by cloudimg

Get a fully secured, production-ready Elasticsearch search and analytics node running on AWS in minutes - no package management, repository configuration, or security bootstrapping required. This AMI eliminates the manual steps that slow down teams deploying Elasticsearch on EC2.

## Who This Is For

Platform engineers, SREs, and DevOps teams running workloads on EC2 who need a search and analytics engine without managed-service lock-in. Ideal for teams that want full control over their Elasticsearch deployment while avoiding the hours of manual installation, Java version management, and security configuration that a bare-metal setup demands.

## Search Stack

Elasticsearch runs as a systemd service in single-node mode. The REST API listens on port 9200, cluster transport on port 9300, and the bundled OpenJDK runtime ships inside the package - no separate Java install or version pinning to manage. Need to scale? Add further nodes by joining them to the cluster at any time.

## Secure First Boot - No Default Credentials

Unlike AMIs that ship with shared or default passwords, every instance of this image generates a unique elastic superuser password on first boot. A one-shot systemd service creates the credential, applies it to the Elasticsearch security index, and stores the plaintext value in a root-only file. The REST API is never exposed without authentication. This eliminates the risk of credential reuse across instances - a common vulnerability in competing images that rely on static default passwords.

## Dedicated Storage Tier

The Elasticsearch data directory (path.data) resides on a separate, independently resizable EBS volume. Index data stays off the OS disk, enabling zero-downtime storage expansion as your data grows. You can resize or change the EBS volume type without disturbing the operating system or Elasticsearch configuration.

## Ready to Query Immediately

The Elasticsearch service, configuration, data directory, and superuser account are all prepared at launch. Connect over SSH, retrieve your unique password from the root-only file, and immediately curl the REST API on port 9200 to index documents, run search queries, and inspect cluster health.

## Security Considerations

• Per-instance unique credentials with no shared secrets
• Root-only credential storage prevents unauthorized access
• Recommend placing the instance in a private VPC subnet
• Configure security groups to restrict ports 9200 and 9300 to trusted CIDR ranges
• EBS encryption is supported - enable it at launch for data-at-rest protection

## Use Case: Log Analytics Pipeline

A DevOps team ingesting application logs from multiple EC2 instances and Lambda functions can ship logs directly to the Elasticsearch REST API on port 9200. With the dedicated EBS volume, retention can grow independently of compute resources. Query logs in near real-time using the search API, build alerting pipelines, and maintain full ownership of your data without external service dependencies.

## Additional Use Cases

• Application and site search with full-text query support
• Security analytics and SIEM backends
• Observability data stores for metrics and traces
• Document and content store search

## Getting Started

1. Subscribe to this AMI on AWS Marketplace

2. Launch an EC2 instance (ensure your security group opens ports 9200 and 9300 only to trusted sources)

3. SSH into the instance

4. Retrieve your unique elastic superuser password from the root-only file

5. Query the REST API: curl -u elastic:YOUR_PASSWORD https://localhost:9200

The included user guide covers index design, ingest pipelines, snapshot configuration, and cluster expansion.
