Terraform seems to ignore "skip_final_snapshot" for rds cluster

[andrei-dascalu]

Hello,

I'm not sure if the following is a terraform or aws provider issue but it sure seems like it's an issue as in my case the request behaves as if "skip_final_snapshot" isn't set or it's always true and it's expecting a "final_snapshot_identifier" (though even when provided the error claims it's not there). I've linked a similar issue as well.

Thanks!

Terraform Version

Terraform v0.11.1
+ provider.aws v1.5.0

Terraform Configuration Files

variable "db_password" {
  description = "Database password"
}

variable "db_name" {
  description = "Database name"
}

resource "aws_rds_cluster_instance" "example" {
  count              = 2
  engine             = "aurora"
  identifier         = "aurora-cluster-demo-${count.index}"
  cluster_identifier = "${aws_rds_cluster.example.id}"
  instance_class     = "db.t2.small"
}

resource "aws_rds_cluster" "example" {
  cluster_identifier = "aurora-cluster-demo"
  availability_zones = ["eu-west-1a", "eu-west-1b"]
  database_name      = "${var.db_name}"
  master_username    = "admin"
  master_password    = "${var.db_password}"
  skip_final_snapshot = true
  final_snapshot_identifier = "whatever"
}
