Amazon Bedrock Demo using Quarkus

This is a sample project, based on https://github.com/vsenger/quarkus-bedrock, that demonstrates how to access Amazon Bedrock from a Quarkus application deployed on AWS Lambda.

Prerequisites

To deploy this demo you need:

Build the application

To build the application, execute the following command in the quarkus-bedrock-demo directory:

quarkus build

Deploy the application

To deploy the application, execute the following command in the quarkus-bedrock-demo directory:

sam deploy --guided

Note: You can accept all default settings, except the following two:

  • AWS Region must be set a region that supports Bedrock, e.g. us-east-1.
  • QuarkusBedrock has no authentication. Is this okay? must be answered with [Y].
Setting default arguments for 'sam deploy'
=========================================
...
AWS Region []: us-east-1
...
QuarkusBedrock has no authentication. Is this okay? [y/N]: Y
...

After successful deployment, you will see the generated output:
