Introduction

This sample application is designed to demonstrate how to generate images using Stable diffusion XL model with Amazon Bedrock APIs using dotnet.

Deployment

1. Set enviornment variables CDK_DEFAULT_ACCOUNT by your AWS account ID and CDK_DEFAULT_REGION
2. Install aws-cdk [https://docs.aws.amazon.com/cdk/v2/guide/cli.html]
3. Build the solution
4. Open command prompt and run below commands
   dotnet build
cdk synth
cdk deploy

Testing

You can test by invoking the API endpoint from any client like Postman. Make sure to replace your API endpoint URL, headers, and payload data and method as “POST”.

https://{api-id}.execute-api.region.amazonaws.com/DEV/image

Request Body:

{
"prompt":"An image for girls having fun with with beautiful colors, nice mountain view, with a river and some drinks",
"seed":0,
"stylePreset":"cinematic"
}

Once you get the successful response which contains a S3 pre-signed URL, copy that and open in the browser. You should be able to see your image.

Cleanup

To save costs, delete the resources you created as part of this sample. Use command below

cdk destroy

Note: S3 bucket used in this solution might not empty while using the cdk destroy command for clean-up, so you need to ensure that the buckets are empty before running destroy command. You can empty the bucket using AWS Console or alternatively using AWS CLI.

aws s3 rm s3://{Amazon S3 Bucket Name} —recursive

You can find Amazon S3 bucket name from cdk deploy command output.
