    Cleanup

    The requirements.txt file is added but never removed, unlike pyproject.toml. This could leave unnecessary files in the image.

    ADD pyproject.toml requirements.txt .
RUN pip install --no-cache-dir . && rm pyproject.toml

    General
    Optimize Docker layer count

    Combine both pip install commands into a single RUN instruction to reduce Docker
    layers

    docker/Dockerfile.lambda [8-9]

    -RUN pip install --no-cache-dir . && rm pyproject.toml
-RUN pip install --no-cache-dir mangum==0.17.0
+RUN pip install --no-cache-dir . mangum==0.17.0 && rm pyproject.toml
    • Apply this suggestion
    Suggestion importance[1-10]: 8

    Why: Combining multiple RUN commands into a single instruction is a Docker best practice that significantly reduces the final image size by minimizing the number of layers. This optimization is particularly relevant for container deployments.

    Clean up unused installation files

    Remove requirements.txt after installation to reduce image size, similar to how
    pyproject.toml is removed

    docker/Dockerfile.lambda [7-8]

     ADD pyproject.toml requirements.txt .
-RUN pip install --no-cache-dir . && rm pyproject.toml
+RUN pip install --no-cache-dir . && rm pyproject.toml requirements.txt
    • Apply this suggestion
    Suggestion importance[1-10]: 7

    Why: Removing requirements.txt after installation is a good practice for reducing Docker image size, consistent with how pyproject.toml is handled. This suggestion follows Docker best practices for minimizing image footprint.

    Learned
    best practice
    Avoid hardcoding dependency versions by using build arguments or environment variables

    The mangum package version is hardcoded to 0.17.0. Consider moving this version
    number to a build argument or environment variable to make it easier to update in
    the future.

    docker/Dockerfile.lambda [9]

    -RUN pip install --no-cache-dir mangum==0.17.0
+ARG MANGUM_VERSION=0.17.0
+RUN pip install --no-cache-dir mangum==${MANGUM_VERSION}
