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
}
}
