Above template is working fine If I remove launch configuration and auto scaling group so definitely problem with either launch config or auto scalling group. I created sample AMI and I am referencing the ID in template. I am getting below error
Received 0 SUCCESS signal(s) out of 1. Unable to satisfy 100% MinSuccessfulInstancesPercent requirement
Can someone help me to figure out the issue. Any help would be appreciated. Thanks
