Dynamic image resizing with Python and Serverless framework

In this example, we set up a dynamic image resizing solution with AWS S3 and a Serverless framework function written in Python. We use Pillow for image resizing.

Pre-requisites

In order to deploy the function, you will need the following:

• API credentials for AWS with persmissions to manage S3, IAM and API Gateway
• If not on Linux - Docker installed locally

Deploying the Serverless project

1. Make a .env file with your AWS credentials, as in .env.example
2. Deploy the Serverless project:

source .env
sls deploy
