Chainguard Container for aws-lambda-python

Minimal base image to run Python applications on AWS Lambda.

Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/aws-lambda-python:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Usage

You can use this image as a base image for your Python Lambda application:

# Build stage
FROM cgr.dev/ORGANIZATION/python:latest-dev AS build-image
WORKDIR /function
COPY requirements.txt requirements.txt
RUN pip install \
    --target /function \
    -r requirements.txt && rm requirements.txt
COPY lambda_function.py lambda_function.py

# Runtime image stage
FROM cgr.dev/ORGANIZATION/aws-lambda-python
COPY --from=build-image /function /function
CMD [ "lambda_function.handler" ]

docker buildx build \
  --platform linux/amd64 \\
  --provenance=false \
  --push -t \
  ACCOUNT_ID.dkr.ecr.REGION.amazonaws.com/aws-lambda-python:test .

This will push a single-architecture image to ECR.

Note that, because Lambda doesn't support multi-architecture images, you must pass --platform. Also, because Lambda doesn't accept Docker's build provenance format, you must pass --provenance=false.

Next, you can deploy the image to Lambda:

aws lambda create-function \
  --function-name aws-lambda-python \
  --region REGION \
  --package-type Image \
  --code ImageUri=ACCOUNT_ID.dkr.ecr.REGION.amazonaws.com/jason-lambda-python:test \
  --role arn:aws:iam::ACCOUNT_ID:role/lambda-ex

Then you can invoke the function:

aws lambda invoke --function-name aws-lambda-python response.json

Then, to clean up, delete the function:

aws lambda delete-function --function-name aws-lambda-python

See https://docs.aws.amazon.com/lambda/latest/dg/images-create.html#images-types for more information about using non-AWS base images with AWS Lambda.

To deploy an arm64 image, use --platform=linux/arm64 when building the image, and --architectures=arm64 when creating the function.

See https://docs.aws.amazon.com/lambda/latest/dg/foundation-arch.html for more information.

What are Chainguard Containers?

Chainguard Containers are minimal container images that are secure by default.

In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a -dev variant.

Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
