lambda-packages

Various popular libraries, pre-compiled to be compatible with AWS Lambda.

Currently includes (at least Python 2.7) support for:

• bcrypt
• cffi
• cryptography
• datrie_extended
• LXML
• misaka
• MySQL-Python
• numpy
• OpenCV
• Pillow (PIL)
• psycopg2
• PyCrypto
• PyNaCl
• pyproj
• python-ldap
• python-Levenshtein
• regex
• xmlsec

This project is intended for use by Zappa, but could also be used by any Python/Lambda project.

Installation

pip install lambda-packages

Usage

The best way to use these packages is with Zappa, which will automatically install the right packages during deployment, and do a million other useful things. Whatever you're currently trying to do on Lambda, it'll be way easier for you if you just use Zappa right now. Trust me. It's awesome. As a bonus, Zappa now also provides support for manylinux wheels, which adds support for hundreds of other packages.

But, if you want to use this project the other (wrong) way, just put the contents of the .tar.gz archive into your lambda .zip.

lambda-packages also includes a manifest with information about the included packages and the paths to their binaries.

from lambda_packages import lambda_packages

print lambda_packages['psycopg2']

#{
#    'python2.7': {
#        'version': '2.6.1',
#        'path': '<absolute-local-path>/lambda_packages/psycopg2/python2.7-psycopg2-2.6.1.tar.gz'
#    }
#}

Contributing

To add support for more packages, send a pull request containing a gzipped tarball of the package (built on Amazon Linux and tested on AWS Lambda) in the appropriate directory, an updated manifest, and deterministic build instructions for creating the archive.

You may find the build.sh script useful as a starting point.

Before contributing, you should also make sure that there is no manylinux wheel on PyPI for your package, as Zappa will automatically use those in addition to lambda-packages.

You may also be interested in this guide on deploying with Zappa and Docker.

Useful targets which don't have manylinux wheels versions include:

• MongoEngine
