CloudFormation `create_change_set` function should have `--no-fail-on-empty-changeset` option.

Is your feature request related to a problem? Please describe. It would be great if cloudformation create_change_set function has --no-fail-on-empty-changeset option.

because I use this function in github actions workflow and it always fails because of no change. https://github.com/LittleWat/cfn-github-action-sample/blob/0906ec5340301adb4010f11f3c3fc27e7958927b/deploy.py#L106-L116

Describe the solution you’d like awscli support --no-fail-on-empty-changeset so boto3 also should support --no-fail-on-empty-changeset option.

Or other solutions?

Hi @LittleWat,

Thanks for writing. The Python SDK boto3 and the AWS CLI use the same API model for this operation. Here’s the docs for the AWS CLI aws cloudformation create-change-set, and I don’t see any reference to the parameter you noted:

https://awscli.amazonaws.com/v2/documentation/api/latest/reference/cloudformation/create-change-set.html

What you’re referring to is the AWS CLI customization aws cloudformation deploy command. This is a separate command provided for the AWS CLI. In order to get the same behavior here, we would need to implement the same thing in boto3 as a high-level library.

Can you describe why you need this as part of the Python SDK instead of using the AWS CLI? Deploying packages was a much more common operation to do through a CLI tool than the SDK.

@kdaily Thank you for passing my feature request to the team! I hope this option to be implemented in the future!
