No attribute for certificate identifier in resource: aws_rds_cluster_instance

[ghost]

This issue was originally opened by @Naveenraaj as hashicorp/terraform#23556. It was migrated here as a result of the provider split. The original body of the issue is below.

---

Current Terraform Version

Terraform v0.12.17

Use-cases

AWS has notified to update the certificate for RDS DBs to rds-ca-2019, i am trying to do it using terraform and i am having resource: aws_rds_cluster_instance .

Above mentioned resource does not have an attribute for specifying the CA Certificate, as per the documentation.
An attribute called ca_cert-identifier is available for similar resource: aws_db_instance.

Attempted Solutions

main.tf:

provider "aws" {
  region = "us-east-1"
}

resource "aws_rds_cluster" "aurora" {
  availability_zones      = ["us-east-1a", "us-east-1b", "us-east-1c"]
  cluster_identifier      = "testingcert"
  engine                  = "aurora-mysql"
  engine_version          = "5.7.12"
  master_username         = "rdsmysql"
  master_password         = "Thisispassword"
  backup_retention_period = 3
  storage_encrypted       = "true"
  apply_immediately       = true
  lifecycle {
    create_before_destroy = true
  }
}

resource "aws_rds_cluster_instance" "cluster_instances" {
  cluster_identifier  = aws_rds_cluster.aurora.id
  instance_class      = "db.t2.small"
  engine              = "aurora-mysql"
  engine_version      = "5.7.12"
  publicly_accessible = true
  apply_immediately   = true
  ca_cert_identifier  = "rds-ca-2019"
}

Ran terraform plan

Result:

terraform plan

Error: Unsupported argument

  on main.tf line 27, in resource "aws_rds_cluster_instance" "cluster_instances":
  27:   ca_cert_identifier  = "rds-ca-2019"

An argument named "ca_cert_identifier" is not expected here.

Proposal

Please let us know, if i am missing anything in my code or this is a new feature that will be implemented in future.

Hello, Can someone please look into this PR, as AWS provider has already added support for the same. We are eagerly waiting for this solution for Terraform 0.12.

Thanks

Support for the ca_cert_identifier argument for the aws_rds_cluster_instance resource was recently merged (#10954) and will release in version 2.44.0 of the Terraform AWS Provider, next Thursday.
