CloudFormation : How to refer to existing AWS Resources

Question

What are the best ways to refer to Existing resources (Lambda, IAM Role, S3 bucket etc) when these are created manually from the console page.

Is it using Import Existing resources and copy Parameters Custom Resources or any other options

Thanks in advance

Answer 1

Yes, you can create a CloudFormation Stack from existing resources. As there are some following steps to do this thing.

• Open the AWS CloudFormation console.
• On the Stacks page, choose Create stack, and then choose With existing resources (import resources).
• Read the Import overview page for a list of things you're required to provide during this operation.
