Dgraph Graph Database - Secured

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

## The Problem: Open Source Dgraph Ships Unsecured

A bare Dgraph deployment exposes full read, write, and admin access - including drop-all - to anyone who can reach the port. There is no built-in access control and no authentication out of the box. Hardening it yourself means installing packages, configuring a reverse proxy, generating credentials, and troubleshooting dependencies. This AMI eliminates that entire process.

## How This AMI Solves It

Every instance generates two independent secrets on first boot - unique per machine and never baked into the image - and fronts the database with a TLS reverse proxy. You move from EC2 launch to a secured, authenticated graph database in minutes with zero manual configuration. Unlike a bare install, the alpha start wrapper is fail-closed: it refuses to start without a token, so the server can never run open.

## Graph Database Stack

• Dgraph v25.3.8 running as two coordinated systemd services from a single Go binary: a cluster coordinator (zero) and a data node (alpha)
• Native GraphQL and DQL query languages over clean HTTP and gRPC endpoints, with schema indexes, ACID transactions, and data import/export
• nginx TLS reverse proxy on port 443 terminating HTTPS and enforcing HTTP basic authentication in front of the alpha HTTP API
• Dedicated EBS data volume for all graph state (raft WAL, postings), independently resizable from the root volume

## Secure First Boot

On first launch a one-shot systemd service generates a per-instance nginx basic-auth username and password and a per-instance Dgraph admin security token, writing the plain-text values to a file readable only by the root OS user. Every request to the HTTP API is refused without the basic-auth credentials. Every administrative operation such as altering the schema additionally requires the security token, and admin access is restricted to the local host. The database processes bind only to the loopback interface and are reached solely through the nginx reverse proxy.

## Security and Encryption Guidance

• Encryption in transit: nginx terminates TLS on port 443 with a per-instance self-signed certificate. Replace it with your own CA-signed certificate for production, or front the instance with a load balancer that terminates TLS.
• Encryption at rest: Enable EBS encryption on the dedicated data volume at launch to protect graph data with AWS-managed or customer-managed KMS keys.
• Network isolation: Deploy in a private VPC subnet and restrict Security Group ingress on port 443 to only the source IPs your workload requires. Ports 8080 and 9080 stay bound to loopback and are never network-exposed.

## Getting Started

Retrieve the generated credentials with sudo cat /root/dgraph-info.txt, then call the HTTPS API with the basic-auth user and password. Set a schema with the admin token, run RDF or GraphQL mutations, and query the graph immediately.

## Use Cases

• Knowledge graphs and recommendations: Query deeply joined relationships in milliseconds through the authenticated HTTPS endpoint while the admin token gates schema changes to your data pipeline only
• Identity and fraud-detection graphs
• Retrieval augmented generation (RAG) knowledge stores
• Social and network relationship graphs
• GraphQL application back ends
