lambda-setuptools 0.2.0

A Command extension to setuptools that allows building an AWS Lamba dist and uploading to S3

Simply add setup_requires=['lambda_setuptools'] as an attribute to your setup.py file

This extension adds two new commands to setuptools:

1. ldist

   • Usage: ldist --include-version=<True | true | Yes | yes | False | false | No | no>

     • Effect: This will build (using bdistwheel_) and install your package, along with all of the dependencies in installrequires_

       • include-version is optional. If not present it will default to True

       • It is highly recommended that you DO NOT include boto3 or botocore in your installrequires_ dependencies as these are provided by the AWS Lambda environment. Include them at your own peril!

       • The result will be in dist/[your-package-name]-[version].zip (along with your wheel)

2. lupload

   • Usage: lupload --access-key=<my_access_key> --secret-access-key=<my_secret> --s3-bucket=<my_S3_bucket> --kms-key-id=<my_KMS_key> --s3-prefix=<my_S3_key_prefix>

     • Effect: This will build (using ldist) and upload the resulting ZIP file to the specified S3 bucket

       • kms-key-id is optional. If it is not provided, standard AES256 encryption will be used

       • s3-prefix is optional. If it is not provided, the ZIP file will be uploaded to the root of the S3 bucket

3. lupdate

   • Usage: lupdate --function-names=<my_function1>,<my_function2>,<my_function3>

     • Effect: This will update the AWS Lambda function code for the listed functions. Functions may be function names, partial ARNs and/or full ARNs.

       • Requires the use of lupload parameters as the S3 object uploaded is used as the function code to update.

This extension also adds three new attributes to the setup() function:

1. lambda_function

   • Usage: lambda_function=<my_package>.<some_module>:<some_function>

   • Effect: ldist will create a root-level python module named *function.py* where packagename is derived from the name attribute. This created module will simply redefine your lambda handler function at the root-level

2. lambda_module

   • Usage: lambda_module=<some_module>

   • Effect: ldist adds the named module to the list of pymodules_ to install, normally at the root level

3. lambda_package

   • Usage: lambda_package=<some_dir>

   • Effect: ldist will copy the contents of the provided directory into the root level of the resulting lambda distribution. The provided directory MUST NOT have an *__init__.py* in it (e.g. - it can’t be a real package)

All ldist attributes can be used in the same setup() call. It is up to the user to ensure that you don’t step all over yourself…

Note that all other commands and attributes in setup.py will still work the way you expect them to.

Enjoy!
