In azure you can connect to azure search service using api keys and managed identities. However, there is no way to set that in the terraform. I n my understanding the use of managed identity is still a preview feature which may have been the reason for this. I would really like to setup my service to use managed identity and since I have been managing all infra things using terraform, I would like to use terraform for this purpose as well. Is there a way to get this done using terraform? Is using terraform with arm template my only option here?
