aws_db_instance

Provides an RDS instance resource.

Example Usage

resource "aws_db_instance" "default" {
	identifier = "mydb-rds"
	allocated_storage = 10
	engine = "mysql"
	engine_version = "5.6.17"
	instance_class = "db.t1.micro"
	name = "mydb"
	username = "foo"
	password = "bar"
	db_subnet_group_name = "my_database_subnet_group"
	parameter_group_name = "default.mysql5.6"
}

Argument Reference

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

The following arguments are supported:

  • allocated_storage - (Required) The allocated storage in gigabytes.
  • engine - (Required) The database engine to use.
  • engine_version - (Required) The engine version to use.
  • identifier - (Required) The name of the RDS instance
  • instance_class - (Required) The instance type of the RDS instance.
  • storage_type - (Optional) One of "standard" (magnetic), "gp2" (general purpose SSD), or "io1" (provisioned IOPS SSD). The default is "io1" if iops is specified, "standard" if not.
  • final_snapshot_identifier - (Optional) The name of your final DB snapshot when this DB instance is deleted. If omitted, no final snapshot will be made.
  • name - (Optional) The DB name to create. If omitted, no database is created initially.
  • 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.
  • username - (Required) Username for the master DB user.
  • availability_zone - (Optional) The AZ for the RDS instance.
  • backup_retention_period - (Optional) The days to retain backups for. Must be 1 or greater to be a source for a Read Replica.
  • backup_window - (Optional) The backup window.
  • iops - (Optional) The amount of provisioned IOPS. Setting this implies a storage_type of "io1".
  • maintenance_window - (Optional) The window to perform maintenance in. Syntax: "ddd:hh24:mi-ddd:hh24:mi". Eg: "Mon:00:00-Mon:03:00". See RDS Maintenance Window docs for more.
  • multi_az - (Optional) Specifies if the RDS instance is multi-AZ
  • port - (Optional) The port on which the DB accepts connections.
  • publicly_accessible - (Optional) Bool to control if instance is publicly accessible.
  • vpc_security_group_ids - (Optional) List of VPC security groups to associate.
  • security_group_names - (Optional/Deprecated) List of DB Security Groups to associate. Only used for DB Instances on the EC2-Classic Platform.
  • db_subnet_group_name - (Optional) Name of DB subnet group
  • parameter_group_name - (Optional) Name of the DB parameter group to associate.
  • storage_encrypted - (Optional) Specifies whether the DB instance is encrypted. The default is false if not specified.
  • apply_immediately - (Optional) Specifies whether any database modifications are applied immediately, or during the next maintenance window. Default is false. See Amazon RDS Documentation for more information.
  • replicate_source_db - (Optional) Specifies that this resource is a Replicate database, and to use this value as the source database. This correlates to the identifier of another Amazon RDS Database to replicate. See DB Instance Replication and Working with PostgreSQL and MySQL Read Replicas for more information on using Replication.

~> NOTE: Removing the replicate_source_db attribute from an existing RDS Replicate database managed by Terraform will promote the database to a fully standalone database.
