lambda-uploader 0.4.0

AWS Python Lambda Packager

Provides a quick command line utility for packaging and publishing Python AWS Lambda functions. This is a work in progress and pull requests are always welcome.

Installation

The latest release of lambda-uploader can be installed via pip:

pip install lambda-uploader

An alternative install method would be manually installing it leveraging setup.py:

git clone https://github.com/rackerlabs/lambda-uploader
cd lambda-uploader
python setup.py install

Configuration File

The lambda uploader expects a directory with, at a minimum, your lambda function and a lambda.json file. It is not necessary to set requirements in your config file since the lambda uploader will also check for and use a requirements.txt file.

Example lambda.json file:

{
  "name": "myFunction",
  "description": "It does things",
  "region": "us-east-1",
  "handler": "function.lambda_handler",
  "role": "arn:aws:iam::00000000000:role/lambda_basic_execution",
  "requirements": ["pygithub"],
  "ignore": [
    "circle.yml",
    ".git",
    "*.pyc"
  ],
  "timeout": 30,
  "memory": 512
}

Command Line Usage

To package and upload simply run the command from within your lambda directory or with the directory as an option.

lambda-uploader ./myfunc

To specify an alternative profile that has been defined in ~/.aws/credentials use the --profile parameter.

lambda-uploader --profile=alternative-profile

To specify an alternative, prexisting virtualenv use the --virtualenv parameter.

lambda-uploader --virtualenv=~/.virtualenv/my_custom_virtualenv

To omit using a virtualenv use the --no-virtualenv parameter.

lambda-uploader --no-virtualenv

If you would prefer to upload another way you can tell the uploader to ignore the upload. This will create a package and leave it in the project directory.

lambda-uploader --no-upload ./myfunc

To publish a version without an alias you would pass the the publish flag.

lambda-uploader -p ./myfunc

If you would like to alias your upload you can pass the alias with the alias flag. The function description will be used when an alias-description is not provided.

lambda-uploader --alias myAlias --alias-description 'My alias description' ./myfunc
