aws	AWS: aws_rds_cluster	docs-aws-resource-rds-cluster	Provides an RDS Cluster Resource

aws_rds_cluster

Provides an RDS Cluster Resource. A Cluster Resource defines attributes that are applied to the entire cluster of RDS Cluster Instances. Use the RDS Cluster resource and RDS Cluster Instances to create and use Amazon Aurora, a MySQL-compatible database engine.

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

Example Usage

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 = "bar"
  backup_retention_period = 5
  preferred_backup_window = "07:00-09:00"
}

~> NOTE: RDS Clusters resources that are created without any matching RDS Cluster Instances do not currently display in the AWS Console.

Argument Reference

For more detailed documentation about each argument, refer to the AWS official documentation.

The following arguments are supported:

• cluster_identifier - (Required) The Cluster Identifier. Must be a lower case string.
• database_name - (Optional) The name for your database of up to 8 alpha-numeric characters. If you do not provide a name, Amazon RDS will not create a database in the DB cluster you are creating
• master_password - (Required) Password for the master DB user. Note that this may show up in logs, and it will be stored in the state file
• master_username - (Required) Username for the master DB user
• final_snapshot_identifier - (Optional) The name of your final DB snapshot when this DB cluster is deleted. If omitted, no final snapshot will be made.
• availability_zones - (Optional) A list of EC2 Availability Zones that instances in the DB cluster can be created in
• backup_retention_period - (Optional) The days to retain backups for. Default 1
• preferred_backup_window - (Optional) The daily time range during which automated backups are created if automated backups are enabled using the BackupRetentionPeriod parameter. Default: A 30-minute window selected at random from an 8-hour block of time per region. e.g. 04:00-09:00
• preferred_maintenance_window - (Optional) The weekly time range during which system maintenance can occur, in (UTC) e.g. wed:04:00-wed:04:30
• port - (Optional) The port on which the DB accepts connections
• vpc_security_group_ids - (Optional) List of VPC security groups to associate with the Cluster
• apply_immediately - (Optional) Specifies whether any cluster modifications are applied immediately, or during the next maintenance window. Default is false. See Amazon RDS Documentation for more information.
• db_subnet_group_name - (Optional) A DB subnet group to associate with this DB instance.
