aws_rds_cluster_instance

Provides an RDS Cluster Resource Instance. A Cluster Instance Resource defines attributes that are specific to a single instance in a RDS Cluster, specifically running Amazon Aurora.

Unlike other RDS resources that support replication, with Amazon Aurora you do not designate a primary and subsequent replicas. Instead, you simply add RDS Instances and Aurora manages the replication. You can use the count meta-parameter to make multiple instances and join them all to the same RDS Cluster, or you may specify different Cluster Instance resources with various instance_class sizes.

For more information on Amazon Aurora, see Aurora on Amazon RDS in the Amazon RDS User Guide.

Example Usage

resource "aws_rds_cluster_instance" "cluster_instances" {
  count              = 2
  identifier         = "aurora-cluster-demo-${count.index}"
  cluster_identifier = "${aws_rds_cluster.default.id}"
  instance_class     = "db.r3.large"
}

resource "aws_rds_cluster" "default" {
  cluster_identifier = "aurora-cluster-demo"
  availability_zones = ["us-west-2a","us-west-2b","us-west-2c"]
  database_name      = "mydb"
  master_username    = "foo"
  master_password    = "barbut8chars"
}
