Deploying Lambda functions with large dependencies can be challenging due to the 250MB layer limit, but using containerized deployment with Docker images provides a workaround.
To implement this method, you need Docker, AWS CLI, and VS Code for creating and deploying a Lambda function.
The process involves creating a source folder with a Python file for the Lambda function, setting up a Dockerfile using the AWS Python base image, creating an Elastic Container Registry (ECR), building and pushing the Docker image to ECR, and creating the Lambda function.
Finally, testing the function confirms its functionality, allowing for customization of the handler and addition of dependencies as needed.
