创建和计划删除AWS云形成堆栈

Question

I am trying to setup an environment on AWS by launching a stack via AWS Cloud Formation template. The stack would be created and then be scheduled for deletion automatically based on the TTL parameter in the template. There seems to be a problem only when the instance is getting launched, it errors out that "Failed to receive 1 resource signal(s) within the specified duration"

If anyone could point out what I am doing wrong in the template, it would be great.

Here is the link for the template in YAML: https://s3.ca-central-1.amazonaws.com/rkbucket028/aws-openshit-cf-template_new.yml

I have already followed this article but there seems to be something wrong with it as well:- https://aws.amazon.com/blogs/devops/scheduling-automatic-deletion-of-application-environments/#

Answer 1

CloudFormation rolls back if any of the resources have failed to be created (ie didnt responed in the predetermined duration). If you believe that it is only the process that is taking longer and not a genuine failure, you can either incorporate the wait condition, or better use resource creation policy time and count.
