Aws-cli: Allow cloudformation deploy to complete successfully if there are no changes

[rtimush]

aws cloudformation deploy fails if there are no changes. However, when it is used as a part of CI/CD pipeline, we usually want to treat this case as a success. It would be nice if there was an option like --allow-empty-changeset, or at least the process exit code was different for "nothing to do" and "failed to do" cases.

This would be a feature request for the cloudformation team, we just wrap their API in a command line utility we don't actually make the APIs themselves.

Best way to do this would be to open a support ticket with your feature request.

If anyone comes across this closed issue, there is a --no-fail-on-empty-changeset option now.

I am running into the same issue, and the --no-fail-on-empty-changeset flag doesn't make a difference. The flag is recognised by the CLI (at least it does not say Unknown option), but it still fails with the error message FAILED. Reason: No updates are to be performed.. @rtimush , are you successfully using this flag?

I have the same issue. --no-fail-on-empty-changeset does not work. Any planning on fixing that? That is a very important option.
