python-lambda-bundler

A simple template for bundling any Python function for Lambda and Amazon Linux.

Note: This template currently bundles Python 3.8, but this can be changed inside build.sh.

Why use Docker?

If you're using a non-Linux operating system as your development machine, you'll need to bundle Python dependencies for Linux somehow. This setup uses the amazonlinux Docker image to bundle Python dependencies for Lambda.

Setup

To build the Lambda zip:

• Create an environment file inside the sh folder called env.sh that exports a LOCAL_PATH variable representing the current directory where the build will occur. Ex:

export LOCAL_PATH=~/Documents/projects/my-folder;

• Add Python package dependencies to build.sh (see # install python dependencies section).
• Start Docker.
• Run sh start.sh.

If you plan on running this Docker setup on multiple projects, you should rename the container as specified inside the start.sh file (which is named as bundler currently) so that a different container that specifies a bind mount with the specific path is used for the project.
