CDK Constructs for AWS Lambda in Python

Amazon Lambda Python Library

---

The APIs of higher level constructs in this module are experimental and under active development. They are subject to non-backward compatible changes or removal in any future version. These are not subject to the Semantic Versioning model and breaking changes will be announced in the release notes. This means that while you may use them, you may need to update your source code when upgrading to a newer version of this package.

---

This library provides constructs for Python Lambda functions.

To use this module, you will need to have Docker installed.

Python Function

Define a PythonFunction:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
lambda.PythonFunction(self, "MyFunction",
    entry="/path/to/my/function", # required
    index="my_index.py", # optional, defaults to 'index.py'
    handler="my_exported_func", # optional, defaults to 'handler'
    runtime=lambda.Runtime.PYTHON_3_6
)

All other properties of lambda.Function are supported, see also the AWS Lambda construct library.

Module Dependencies

If requirements.txt exists at the entry path, the construct will handle installing all required modules in a Lambda compatible Docker container according to the runtime.

├── lambda_function.py # exports a function named 'handler'
├── requirements.txt # has to be present at the entry path
