Update iam_database_authentication_enabled terraform – Amazon Web Sevices

I have a deployment with an rds database. Initially we set the iam_database_authentication_enabled to false then run a script setting the database up along with giving the database user the rds_iam role. After that we run apply once more but with iam_database_authentication_enabled set to true. This is achieved by having two .tfvars files. Problem is, the iam_database_authentication_enabled is never updated in AWS. I can see when running terraform plan that the field will be updated but in fact it never is. What am I doing wrong here?

    Found a way around it using aws cli:

    aws rds modify-db-instance 
  --db-instance-identifier mydbinstance 
  --apply-immediately 
  --enable-iam-database-authentication

    It will likely be applied in the next rds maintenance window. But if you want to apply immediately, you can use Terraform argument:

    apply_immediately = true

    It sounds like you didn’t set the apply_immediately attribute to true in your aws_db_instance Terraform code. If you didn’t set that, then the setting will be changed in AWS, but not applied to the running database instance until the next restart.
