Bare minimum

Lambpack’s purposely minimal - it only packages functions. No uploading, no publishing, no aspirations to become a framework.

Command-line example

Given a directory my-function containing:

• index.py with a handler(event, context) function.

• An optional requirements.txt listing required packages.

Run the following to get packaged.zip, ready for upload to AWS Lambda:

$ pip install lambpack
$ lambpack my-function packaged.zip index.handler --env DEBUG=yes --env MY_OTHER_FLAG=123

Your function can access the --env variables via os.environ.

API example

As above, but via the API:

import lambpack

lambpack.to_zip(
    path="my-function",
    dest="packaged.zip",
    handler="index.handler",
    env={
        "ENV": "prod"
    }
)
