Lambda Function for Creating AMIs using EventBridge Schedule

This CloudFormation template deploys a Lambda function that creates Amazon Machine Images (AMIs) based on a schedule defined in Amazon EventBridge. This can be useful for automated backups or snapshotting of EC2 instances.

Supported parameters:

createAmisAt: cron schedule to create AMIs, by default at midnight. More: https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-cron-expressions.html

createAmisLambdaTimeout: If you have lots of ec2 instances - it requires to adjust this parameter

deleteOldAmisAt: cron schedule to delete old AMIs, by default at 2AM. More: https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-cron-expressions.html

keepAmis: How much AMIs you'd like to keep, 3 by default

rotateAmisLambdaTimeout: If you have lots of AMIs - it requires to adjust this parameter

Deployment Steps

Using AWS CLI

1. Prerequisites: Ensure you have AWS CLI installed and configured with the necessary permissions.

2. Clone the Repository: Clone this GitHub repository to your local machine.

   git clone https://github.com/RealArtemiy/ami-scheduler.git

3. Navigate to Template Directory: Enter into the directory containing your CloudFormation template.

   cd ami-scheduler

4. Deploy Stack: Use the AWS CLI to deploy the CloudFormation stack. Replace <stack_name> with your desired stack name.

   aws cloudformation create-stack --stack-name <stack_name> --template-body file://cloudformation.yml --capabilities CAPABILITY_IAM

5. Monitor Deployment: Monitor the stack creation process either via the AWS Management Console or using the AWS CLI.

   aws cloudformation describe-stacks --stack-name <stack_name> --query "Stacks[0].StackStatus"

Using AWS Management Console (UI)

1. Sign in to AWS Console: Sign in to your AWS Management Console.

2. Navigate to CloudFormation: Go to the CloudFormation service.

3. Create Stack: Click on "Create stack" and choose "With new resources (standard)".

4. Upload Template: Upload the CloudFormation template file (cloudfomation.yml).

5. Specify Stack Details: Provide a stack name and any necessary parameters.

6. Configure Stack Options: Configure stack options as needed, then proceed to create the stack.

7. Monitor Deployment: Monitor the stack creation process in the CloudFormation dashboard.
