guardduty-tester.template fails due to`BastionAutoScalingGroup`

[ken5scal]

Running the template, I encountered a failure in CloudFormation-Stack because it failed to create BastionAutoScalingGroup. The error was Received 0 SUCCESS signal(s) out of 1. Unable to satisfy 100% MinSuccessfulInstancesPercent requirement.

I tried to build the stack with the following parameters under the region ap-northeast-1:

VPCCIDR:  172.16.0.16/28
RemoteAccessCIDR: 0.0.0.0/0
PublicSubnetCIDR:172.16.0.0/28
PrivateSubnetCIDR: 172.16.0.16/28
AvailabilityZones: ap-northeast-1a

I recreated the stack, and it seems the AutoScalingGroup has created w/o problem; however for some reason, the stack thinks it's failed and executes rollback.

I turned off protection from delete option and re-created the stack. It still fails but creates an instance RedTeam. However, I found that the instance has nothing in it required for running a test such as guadduty_tester.sh, nmap and so on.
