aws-lambda-thumb

AWS Lambda. Creates/removes thumbnails via Python 3.8. 8x faster than nodejs.

thumb_create function creates thumbnail in thumbnails bucket when original image is uploaded.

thumb_delete function removes thumbnail from thumbnails bucket when original image is removed.

Usage

1. Add bucket for thumbnails with suffix -thumbs. E.g. for mybucket new bucket should be mybucket-thumbs.
2. Add object delete permission ("s3:DeleteObject") to your lambda s3 role lambda_s3_exec_role.
3. Create .zip archives in dist/

./pack.sh thumb_create
./pack.sh thumb_delete
./pack.sh python_layer # (requires virtualenv & docker)
./pack.sh ffmpeg_layer # (requires wget)

4. Add python and ffmpeg layers to thumb_create function.

Handlers will be thumb_create.handler and thumb_delete.handler for lambda functions.
