AWS Lambda python managed by uv

Obsoleted by: https://docs.astral.sh/uv/guides/integration/aws-lambda/

This python demo project is managed by uv - the next gen python package and project manager.

The trick to make this work, is to copy the files/directories from .venv/lib/python${PYTHON_VERSION}/site-packages/ to /var/task/ flat. Also you must specify --no-editable in uv sync so that the project is not symlinked.

Project created with uv init --app --package, which uses the src/ layout (which I prefer anyway).

Quickstart

podman build -t demo-uv-aws-lambda .
podman run --rm -p 9000:8080 demo-uv-aws-lambda

In another terminal/shell

curl "http://localhost:9000/2015-03-31/functions/function/invocations" \
    -d '{"payload":"hello world!"}'
