This is the python code for the lambda cumulus-post-map-payload-grouping. It simply takes in the output from a Distributed Mode AWS Step Function Map and obtains the status of each mapped execution.
Output of the map; this function does not utilize the cumulus library so is relatively bare bones to other lambdas
This page contains some good info on the overall "building a zip with poetry that's compatible with AWS Lambda".
TL;DR
sh ./build.sh;
to run the following commands in order and build the cumulus-pre-map-payload-grouping.zip artifact
This command creates the dist/ folder:
poetry build
This command downloads the dependency files from the just created .whl file, along with the lambda_handler function in cumulus_post_map_payload_grouping/cumulus_post_map_payload_grouping.py, and places them in the package folder:
poetry run pip install --upgrade -t package dist/*.whl
Note that moto is not being pulled in. I've specifically excluded it via having moto as tool.poetry.dev-dependencies only (via the pyproject.toml file)
The last command used is:
cd package ; zip -r ../artifact.zip . -x '*.pyc'
Which zips and creates the artifact.zip file, containing all files found in package/ excluding .pyc files
Then upload artifact.zip to any location you plan to use it
- Upload directly as a lambda with
aws lambda update-function-code - Upload to your AWS S3
lambdas/folder so that your Cumulus Terraform Build can use it
