Terraform Setup for Scheduled Lambda Functions

If you are looking to schedule your Lambda functions using cron expressions, you’re in the right place!

Module

To begin with, set up a module where you pass in your variables such as the schedule (cron expression) parameter.

Lambda

For testing purposes, I am using a Hello World Python lambda function. You can send API requests or perform other required actions using your Lambda function.

The Terraform setup for a Lambda function is pretty straight forward. Ensure that your AWS role has all the required permissions. For example, if you are trying to access any S3 buckets via the Lambda function, you need to give it permissions to access S3.
