Trouble with aws_rds_cluster and aurora-mysql

Terraform Providers AWS
1

Hey all y’all,

Working on my first adventure with terraform - love the idea of it, but have been bashing my head against the wall on configuring an rds cluster using aurora-mysql version 5.7.x . Here the snippet:

resource "aws_rds_cluster" "mysql" {
  cluster_identifier = "d30-${var.environment}-mysql"
  availability_zones = ["us-east-1a", "us-east-1b", "us-east-1c"]
  database_name      = "xxx"
  master_username    = "yyyy"
  master_password    = "zzzz"
  engine             = "aurora-mysql"
  engine_version       = "5.7.mysql_aurora.2.03.2"
  skip_final_snapshot  = true
}

When running with TRACE enabled, I see that the config that goes to AWS always specifies “Engine: aurora” - which, I think, leads to the error of:

Error: error creating RDS cluster: InvalidParameterValue: The engine mode provisioned you requested is currently unavailable.

Looking in the TRACE, I see this block:

Any thoughts on how to get this to go? Is nobody creating Aurora clusters of the 5.7 mysql version of Aurora?

Best,
