Is there a way to use PyGithub on AWS Lambda

Im a big fan of PyGithub. I want use this library on AWS Lambda. But unfortunately,Im not able compile and use the source files of PyGithub.

I tried to download it from pypi, then compressed it as zip --> uploaded.

## app.py file
from github import Github

# using username and password
g = Github("username", "password")

def handler(event, context):
    for repo in g.get_user().get_repos():
        print(repo.name)
        repo.edit(has_wiki=False)

But its throwing an error.

{
  "errorMessage": "Unable to import module 'app': No module named 'jwt'",
  "errorType": "Runtime.ImportModuleError"
}

Is there any way to use this library on Lambda?

Solution

Yes. One way would be through lambda layers.

To verify this possibility, I just created a custom layer with pygithub and can confirm that it works.

The technique used includes docker tool described in the recent AWS blog:

How do I create a Lambda layer using a simulated Lambda environment with Docker?

I created the layer as follows:

Create empty folder, e.g. mylayer.
Go to the folder and create requirements.txt file with the content of

PyGithub

Run the following docker command (for lambda with python 3.8):

docker run -v "$PWD":/var/task "lambci/lambda:build-python3.8" /bin/sh -c "pip install -r requirements.txt -t python/lib/python3.8/site-packages/; exit"

Create layer as zip:

zip -r mypygithublayer.zip python > /dev/null

Create lambda layer based on mypygithublayer.zip in the AWS Console. Don't forget to specify Compatible runtimes to python3.8.
Test the layer in lambda using the following lambda function:

import json

from github import Github

def lambda_handler(event, context):
    
    print(dir(Github))

The function executes correctly:
