Pre-requisites

1. AWS Account
2. EC2 Instances in Running/Stopped State

Steps

1. Login in to the AWS Console and search for CloudFormation
2. Click on Create stack ---> With new resources (standard)
3. Choose Template is ready ---> Upload a template file ---> Choose file and click on Next
4. Give the stack some name ---> ec2-instance-auto-shutdown
5. Configure the settings as per your need (optional) and click on Submit
6. Once the Stack is successfully created, click on Resources tab to view all the newly created resource (Lambda Function, IAM Role and Event Rule)
7. Now the Event Rule will trigger the Lambda function based on the cron job (by default it is MON-FRI 5 PM UTC)
8. You can also manually test the lambda function by creating a sample test event and running it.

Note

1. The exclusion of auto shutdown of instances is based on the tag "exception" attached to the instance, irrespective of the case.
