#db_subnet_group_nameString

Specifies a DB subnet group for the DB instance. The new DB instance will be created in the VPC associated with the DB subnet group. If no DB subnet group is specified, then the new DB instance is not created in a VPC.

Constraints:

  • Can only be specified if the source DB instance identifier specifies a DB instance in another AWS Region.

  • The specified DB subnet group must be in the same AWS Region in which the operation is running.

  • All Read Replicas in one AWS Region that are created from the same source DB instance must either:>

    • Specify DB subnet groups from the same VPC. All these Read Replicas will be created in the same VPC.

    • Not specify a DB subnet group. All these Read Replicas will be created outside of any VPC.

Constraints: Must contain no more than 255 alphanumeric characters, periods, underscores, spaces, or hyphens. Must not be default.

Example: mySubnetgroup

Returns:

  • (String)

#kms_key_idString

The AWS KMS key ID for an encrypted Read Replica. The KMS key ID is the Amazon Resource Name (ARN), KMS key identifier, or the KMS key alias for the KMS encryption key.

If you specify this parameter when you create a Read Replica from an unencrypted DB instance, the Read Replica is encrypted.

If you create an encrypted Read Replica in the same AWS Region as the source DB instance, then you do not have to specify a value for this parameter. The Read Replica is encrypted with the same KMS key as the source DB instance.

If you create an encrypted Read Replica in a different AWS Region, then you must specify a KMS key for the destination AWS Region. KMS encryption keys are specific to the AWS Region that they are created in, and you cannot use encryption keys from one AWS Region in another AWS Region.

Returns:

  • (String)

#pre_signed_urlString

The URL that contains a Signature Version 4 signed request for the CreateDBInstanceReadReplica API action in the source AWS Region that contains the source DB instance.

You must specify this parameter when you create an encrypted Read Replica from another AWS Region by using the Amazon RDS API. You can specify the source region option instead of this parameter when you create an encrypted Read Replica from another AWS Region by using the AWS CLI.

The presigned URL must be a valid request for the CreateDBInstanceReadReplica API action that can be executed in the source AWS Region that contains the encrypted source DB instance. The presigned URL request must contain the following parameter values:

  • DestinationRegion - The AWS Region that the encrypted Read Replica will be created in. This AWS Region is the same one where the CreateDBInstanceReadReplica action is called that contains this presigned URL.

    For example, if you create an encrypted DB instance in the us-west-1 region, from a source DB instance in the us-east-2 region, then you call the CreateDBInstanceReadReplica action in the us-east-1 region and provide a presigned URL that contains a call to the CreateDBInstanceReadReplica action in the us-west-2 region. For this example, the DestinationRegion in the presigned URL must be set to the us-east-1 region.

  • KmsKeyId - The KMS key identifier for the key to use to encrypt the Read Replica in the destination AWS Region. This is the same identifier for both the CreateDBInstanceReadReplica action that is called in the destination AWS Region, and the action contained in the presigned URL.

  • SourceDBInstanceIdentifier - The DB instance identifier for the encrypted DB instance to be replicated. This identifier must be in the Amazon Resource Name (ARN) format for the source AWS Region. For example, if you are creating an encrypted Read Replica from a DB instance in the us-west-2 region, then your SourceDBInstanceIdentifier looks like the following example: arn:aws:rds:us-west-2:123456789012:instance:mysql-instance1-20161115.

#publicly_accessibleBoolean

Specifies the accessibility options for the DB instance. A value of true specifies an Internet-facing instance with a publicly resolvable DNS name, which resolves to a public IP address. A value of false specifies an internal instance with a DNS name that resolves to a private IP address.

Default: The default behavior varies depending on whether a VPC has been requested or not. The following list shows the default behavior in each case.

  • Default VPC:true

  • VPC:false

If no DB subnet group has been specified as part of the request and the PubliclyAccessible value has not been set, the DB instance will be publicly accessible. If a specific DB subnet group has been specified as part of the request and the PubliclyAccessible value has not been set, the DB instance will be private.

Returns:

  • (Boolean)

#source_db_instance_identifierString

The identifier of the DB instance that will act as the source for the Read Replica. Each DB instance can have up to five Read Replicas.

Constraints:

  • Must be the identifier of an existing MySQL, MariaDB, or PostgreSQL DB instance.

  • Can specify a DB instance that is a MySQL Read Replica only if the source is running MySQL 5.6.

  • Can specify a DB instance that is a PostgreSQL DB instance only if the source is running PostgreSQL 9.3.5 or later.

  • The specified DB instance must have automatic backups enabled, its backup retention period must be greater than 0.

  • If the source DB instance is in the same AWS Region as the Read Replica, specify a valid DB instance identifier.

  • If the source DB instance is in a different AWS Region than the Read Replica, specify a valid DB instance ARN. For more information, go to Constructing a Amazon RDS Amazon Resource Name (ARN).

Returns:

  • (String)
