Cleanup

If you’re running in an account that was created for you as part of an AWS event, there’s no need to go through the cleanup stage - the account will be closed automatically.
If you’re running in your own account, make sure you run through these steps to make sure you don’t encounter unwanted costs.

  1. If you haven’t already, terminate the EC2 instance that was detached from the EC2 Auto Scaling group in the previous step.

  2. Delete all manually created resources.

    aws autoscaling delete-auto-scaling-group --auto-scaling-group-name runningAmazonEC2WorkloadsAtScale --force-delete
        
    aws deploy delete-deployment-group --application-name koelApp --deployment-group-name koelDepGroup
        
    aws deploy delete-application --application-name koelApp
        
    aws s3 rm s3://$codeDeployBucket --recursive
            
    aws elbv2 delete-load-balancer --load-balancer-arn $alb_arn
    
    sleep 5
        
    aws elbv2 delete-target-group --target-group-arn $tg_arn
        
    aws rds delete-db-instance --db-instance-identifier runningAmazonEC2WorkloadsAtScale --skip-final-snapshot
        
    aws ec2 delete-launch-template --launch-template-name runningAmazonEC2WorkloadsAtScale
    
    aws cloudformation delete-stack --stack-name spotinterruptionhandler
        
    
  3. Finally, delete the CloudFormation stack itself.

    aws cloudformation delete-stack --stack-name runningAmazonEC2WorkloadsAtScale
