Resize4Me

Upload an image to an S3 bucket and see them magically being resized in other buckets!

A Lambda function will resize images uploaded to your source_bucket into any destination_buckets.

A Flask API will also be deployed if, you want an endpoint to upload the images. To use it, just make a POST with a file form-data parameter.

Configuration

Clone this repository, configure your AWS keys and create all buckets used.

Specify your buckets in resize4me_settings.json:

{
    // Bucket that will receive the files to be resized
    "source_bucket": "resize4me",

    // Buckets to receive the resized images,
    // containing the bucket name and the base width for resizing, in pixels.
    "destination_buckets": [
        {
            "name": "resize4me-300px",
            "width_size": 300
        }, 
        {
            "name": "resize4me-600px",
            "width_size": 600
        }
    ]
}

Configure your deployment in zappa_settigs.json:

{
    "production": {
        // Event that generate the images, make sure to specify
        // your source bucket here: arn:aws:s3:::<your-source-bucket>
        "events": [{
            "function": "resize4me.lambda_handler",
            "event_source": {
                "arn": "arn:aws:s3:::resize4me",
                "events": [
                    "s3:ObjectCreated:*"
                ]
            }
        }],
        "profile_name": "default",
        "aws_region": "us-east-1",
        "s3_bucket": "zappa-resize4me",
        "timeout_seconds": 30,

        // If you don't want the Flask API, please remove the line below
        "app_function": "app.app",
        // And uncomment this one
        "apigateway_enabled": false
    }
}
