certbot-lambda

A lambda function to get and renew FREE SSL certificates using Certbots. I'm using it to automatically request and renew all SSL certificates of my CloudFront websites.

• Automatic S3 hosting verification
• ACM certificate import (CloudFront)
• CloudWatch daily event to check if renew is needed
• CloudFormation template to build stack

Instructions

Use make lambda-build to build lambda source package.

Use make BUCKET=your_bucket_name create-stack to upload source package in a bucket and deploy CloudFormation stack.
