A simple image resize lambda function, written in Rust.
This binary responds to Amazon S3 events and triggers a resize on the uploaded image with the sizes specified. Right now you can only resize on the width of an image.
This binary relies on two env vars:
SIZES, an array if sizes (export SIZES=200,300,400)REPLACEMENTS, an array of replacements for the path (export REPLACEMENTS="original:resized")
Use Lambda-Rust docker image to compile this binary. With Docker running run the following command to build a release.
make build
You can find the (zipped) bootstrap ready for upload to AWS Lambda in target/lambda/release/bootstrap.zip
