AWS Python Lambda Packager
Project description
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
