aws_lbd_art_builder_uv 0.1.1

AWS Lambda Artifact UV Builder

---

Welcome to aws_lbd_art_builder_uv Documentation

aws_lbd_art_builder_uv is the uv backend for aws_lbd_art_builder_core, providing automated AWS Lambda layer builds using uv as the package manager.

It offers two builders:

• UvLambdaLayerLocalBuilder — runs uv sync directly on the host machine. Fast, no Docker required. Best for pure-Python dependencies.

• UvLambdaLayerContainerBuilder — runs uv sync inside an AWS SAM Docker image to produce Linux-compatible binaries. Required when your layer includes packages with C extensions (e.g. numpy, pandas).

Both builders follow a 4-step workflow: Preflight Check → Prepare Environment → Execute Build → Finalize Artifacts. The output is a artifacts/python/ directory ready to be zipped and published as a Lambda layer. Combine with aws_lbd_art_builder_core’s package, upload, and publish steps for a complete deployment pipeline.

Features:

• Reproducible builds via uv sync --frozen with lock files

• Private PyPI index support (e.g. AWS CodeArtifact) via credential injection

• Artifact validation — verify installed packages match pyproject.toml dependencies

• Pure-stdlib container script — no pip install needed inside the container
