Awesome!!, but how do you handle aliases and versioning with preparing?

Am having a problem when creating an alias in TF because it needs to be "prepared" to do so. Should I use some depends on my alias using the null resource? (or something like that)

Thanks for your comment.

An alias must be (re-created) when there are changes that require preparing, so the agent resource and the null resource for preparing action group changes should be added to `depends_on` for the alias resource.

Furthermore, the alias must be re-created upon changes to the above. So you may need to use the `replace_triggered_by` meta-argument to force re-creation based on changes to the agent and the null resource's ID. I've not yet tried this myself but see if this works.
