AWS Lambda Compilation and Deployment tool for Python 3.7 Lambda Functions

AWS Lambda Compilation And Deployment

This is a simple config/tool for compiling and deploying AWS Lambda functions in Python 3.7.

Requirements and Dependencies

Project Dependencies

The only dependency for this project is Docker, the rest is taken care of by a custom Docker image!

Local File Requirements

• An envfile (.env) is needed to set the AWS credentials and Lambda function name. A sample file is provided to show what is needed.
• A requirements.txt is also needed to set the Lambda functions dependencies.

Installation and Use

Simply drop the docker-compose.yml file into your Lambda project (or your Python files into this project) and run docker-compose up --build.

This will create a local docker container, which is used to download the Python packages, zip the project into a deployment package and then deploy it to Lambda.

The deployment package zipfile is left in the working directory, whereas the directory with the Python packages is removed upon deployment.

Docker Image Config

The directory docker_image_config holds two files: the Dockerfile used in creating the custom Docker image; and the bash script used in deploying the Lambda function. These are not used as part of the compilation and deployment process.
