AWS Lambda / S3 / Terraform image processing infrastructure

Working proof-of-concept:

• add image file to S3 input bucket ->
• automatically trigger Lambda function ->
• process image (invert colors example) ->
• save to S3 output bucket

Deploy with:

cd terraform
terraform apply

Current limitations

1. Python packages are simply saved to terraform/src/package:

   pip install --target ./package pillow
   

2. terraform/src/lambda.py contains hardcoded TARGET_S3_BUCKET
