RDS DB clusters should have automatic minor version upgrade enabled¶

This control checks if automatic minor version upgrade is enabled for an Amazon RDS database cluster. The control fails if automatic minor version upgrade isn't enabled for an RDS cluster.

How to fix¶

Attribute auto_minor_version_upgrade of aws_rds_cluster_instance must be true.

Implementation options¶

Choose the option that matches how you manage Terraform. All options satisfy this control.

Option 1: Terraform AWS provider resources¶

If you manage resources directly, configure the relevant Terraform AWS provider resources to meet this control. See docs for the resources involved: aws_rds_cluster_instance.

resource "aws_rds_cluster_instance" "this" {
  cluster_identifier = "pofix-example-cluster"
  engine             = "aurora-mysql"
  instance_class     = "db.t3.medium"

  auto_minor_version_upgrade = true
}

Which option should I choose?

Compliance.tf module (recommended): controls enforced by default and mapped to frameworks.
Open source module (terraform-aws-modules): compatible by design with compliance.tf. Same variable names for an easy, low-change migration path when you are ready.
Terraform AWS provider resources: manage Terraform resources directly.
