How To Manage an Amazon Bedrock Agent Using Terraform

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.

Thanks for your comment!

This new argument is only part of the solution, as changes to action groups still requires a PrepareAgent call. There is also a similar case with knowledge base attachments. Nonetheless it's a good idea to add the argument so there's one less dependency - I'll update the blog post and code example soon.

Hopefully I can get to adding similar arguments to the action group and KB resources, unless there are takers :)
