DMS replication instances should have automatic minor version upgrade enabled¶

This control checks if automatic minor version upgrade is enabled for an AWS DMS replication instance. The control fails if automatic minor version upgrade isn't enabled for a DMS replication instance.

How to fix¶

Attribute auto_minor_version_upgrade of aws_dms_replication_instance must be true.

Implementation options¶

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

Option 1: Open source module (`terraform-aws-modules`)¶

If you use terraform-aws-modules/dms/aws, configure the required module inputs to satisfy this control. You can later migrate to the compliance.tf module with minimal changes because it is compatible by design.

module "dms" {
  source  = "terraform-aws-modules/dms/aws"
  version = ">=2.0.0"

  repl_instance_class                  = "dms.t3.micro"
  repl_instance_id                     = "abc123"
  repl_instance_vpc_security_group_ids = ["sg-12345678"]
  repl_subnet_group_subnet_ids         = ["subnet-12345678", "subnet-12345678"]

  repl_instance_auto_minor_version_upgrade = true
}

Option 2: 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_dms_replication_instance.

resource "aws_dms_replication_instance" "this" {
  replication_instance_class = "dms.t3.micro"
  replication_instance_id    = "pofix-example-repl"

  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.
