sam should only deploy a new version if code or relevant config has changed

See original GitHub issue

Description:

I have a function described in template.yaml. I have AutoPublishAlias w/ Provisioned Concurrency enabled. I deploy and stack and it creates and completes. I add a cloudwatch alarm to template.yaml. I deploy and the changeset says it’s going to deploy a version of the lambda, even though nothing changed for the code or config. I deploy and it creates the new version of the lambda and adds the alarm. I remove the alarm from template.yaml, and deploy and it yet again wants to deploy a new version of the lambda, while also removing the alarm.

Expected result:

If the code or config for the lambda doesn’t change, no new version should be deployed. Just make changes to the other resources in template.yaml as needed.

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

OS: macOS Big Sur 11.3.1
sam --version:S AM CLI, version 1.23
AWS region: us-west-2

Maybe sam could prompt the user to move source code to a separate directory, as a best practice.

Thanks for the suggestion. We are also exploring other options like excluding certain directories and files in CodeUri, like template.yaml in your case.

I am closing this for now. Please let us know if you experience further issues.
