Bedrock BDA Multimodal Media Solution - Backend

Table of contents

Local deployment

In order to deploy this project, you need to have installed:

With all installed, run this command:

$ python3 -V && cdk --version && docker info -f "{{.OperatingSystem}}"
Python 3.12.2
2.176.0 (build 899965d)
Docker Desktop

An output similar to the above indicates that all is ok to proceed.

If any of these commands fails, you can revisit the documentation and check for possible steps you have forgotten to complete. Ensure that your CDK version is using CDK V2, by checking if the second line of the output follows the pattern 2...

Having those installed, it is time to configure your environment to connect to your AWS Account. To set up your local environment to use such an AWS account you can follow the steps described at https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-quickstart.html

Get source code

If not done already, clone this repository

git clone https://github.com/aws-samples/generative-ai-cdk-constructs-samples.git

Enter the backend directory

cd samples/multimodal-rag/backend

Create Python virtual environment

To manually create a virtualenv on MacOS and Linux:

python3 -m venv .venv

After the init process completes and the virtualenv is created, you can use the following step to activate your virtualenv.

source .venv/bin/activate

If you are a Windows platform, you would activate the virtualenv like this:

.venv\Scripts\activate.bat

Once the virtualenv is activated, you can install the required dependencies.

pip install -r requirements.txt

Bootstrap CDK

Run the following

cdk bootstrap

Deployment

  1. Run AWS CDK Toolkit to deploy the Backend stack with the runtime resources.

    cdk deploy --require-approval=never

  2. Any modifications made to the code can be applied to the deployed stack by running the same command again.

    cdk deploy --require-approval=never

Samples files

The samples folder contains samples files you can use to test the application.

User creation

First, locate the Cognito User Pool ID, through the AWS CLI:

$ aws cloudformation describe-stacks --stack-name BDAMediaSolutionBackendStack --query "Stacks[0].Outputs[?contains(OutputKey, 'UserPoolId')].OutputValue"

[
    "OutputValue": "<region>_a1aaaA1Aa"
]

You can then go the Amazon Cognito page at the AWS Console, search for the User Pool and add users.
