aws LAMP_Single_Instance stack create fails

Question

Trying to create a simple LAMP stack on aws using AWS CloudFormation Sample Template LAMP_Single_Instance template.

On creating the stack, I get the following event - "Internal Failure. Rollback requested by user."

No clues provided on why this failed.

Answer 1

You can inspect the CloudFormation events tab on the management console (or with describe-stack-events on the CLI) and check what went wrong. In this single instance stack, probably CloudFormation was unable to create the instance, check the parameter values. For example, the key pair name should not have the ".pem" extension of the file, if that was supplied.
