Request Parameters Response Elements Errors Examples See Also

CreateDBCluster

Creates a new Amazon Aurora DB cluster or Multi-AZ DB cluster.

If you create an Aurora DB cluster, the request creates an empty cluster. You must explicitly create the writer instance for your DB cluster using the CreateDBInstance operation. If you create a Multi-AZ DB cluster, the request creates a writer and two reader DB instances for you, each in a different Availability Zone.

You can use the ReplicationSourceIdentifier parameter to create an Amazon Aurora DB cluster as a read replica of another DB cluster or Amazon RDS for MySQL or PostgreSQL DB instance. For more information about Amazon Aurora, see What is Amazon Aurora? in the Amazon Aurora User Guide.

You can also use the ReplicationSourceIdentifier parameter to create a Multi-AZ DB cluster read replica with an RDS for MySQL or PostgreSQL DB instance as the source. For more information about Multi-AZ DB clusters, see Multi-AZ DB cluster deployments in the Amazon RDS User Guide.

EngineLifecycleSupport

The life cycle type for this DB cluster.

Note

By default, this value is set to open-source-rds-extended-support, which enrolls your DB cluster into Amazon RDS Extended Support. At the end of standard support, you can avoid charges for Extended Support by setting the value to open-source-rds-extended-support-disabled. In this case, creating the DB cluster will fail if the DB major version is past its end of standard support date.

You can use this setting to enroll your DB cluster into Amazon RDS Extended Support. With RDS Extended Support, you can run the selected major engine version on your DB cluster past the end of standard support for that engine version. For more information, see the following sections:

Amazon Aurora (PostgreSQL only) - Using Amazon RDS Extended Support in the Amazon Aurora User Guide

Required: No

KmsKeyId

The AWS KMS key identifier for an encrypted DB cluster.

The AWS KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key. To use a KMS key in a different AWS account, specify the key ARN or alias ARN.

When a KMS key isn't specified in KmsKeyId:

If ReplicationSourceIdentifier identifies an encrypted source, then Amazon RDS uses the KMS key used to encrypt the source. Otherwise, Amazon RDS uses your default KMS key.
If the StorageEncrypted parameter is enabled and ReplicationSourceIdentifier isn't specified, then Amazon RDS uses your default KMS key.

There is a default KMS key for your AWS account. Your AWS account has a different default KMS key for each AWS Region.

If you create a read replica of an encrypted DB cluster in another AWS Region, make sure to set KmsKeyId to a KMS key identifier that is valid in the destination AWS Region. This KMS key is used to encrypt the read replica in that AWS Region.

Required: No

MasterUserSecretKmsKeyId

The AWS KMS key identifier to encrypt a secret that is automatically generated and managed in AWS Secrets Manager.

This setting is valid only if the master user password is managed by RDS in AWS Secrets Manager for the DB cluster.

The AWS KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key. To use a KMS key in a different AWS account, specify the key ARN or alias ARN.

If you don't specify MasterUserSecretKmsKeyId, then the aws/secretsmanager KMS key is used to encrypt the secret. If the secret is in a different AWS account, then you can't use the aws/secretsmanager KMS key to encrypt the secret, and you must use a customer managed KMS key.

There is a default KMS key for your AWS account. Your AWS account has a different default KMS key for each AWS Region.

The AWS KMS key identifier for encryption of Performance Insights data.

The AWS KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key.

If you don't specify a value for PerformanceInsightsKMSKeyId, then Amazon RDS uses your default KMS key. There is a default KMS key for your AWS account. Your AWS account has a different default KMS key for each AWS Region.

PreSignedUrl

When you are replicating a DB cluster from one AWS GovCloud (US) Region to another, an URL that contains a Signature Version 4 signed request for the CreateDBCluster operation to be called in the source AWS Region where the DB cluster is replicated from. Specify PreSignedUrl only when you are performing cross-Region replication from an encrypted DB cluster.

The presigned URL must be a valid request for the CreateDBCluster API operation that can run in the source AWS Region that contains the encrypted DB cluster to copy.

The presigned URL request must contain the following parameter values:

KmsKeyId - The AWS KMS key identifier for the KMS key to use to encrypt the copy of the DB cluster in the destination AWS Region. This should refer to the same KMS key for both the CreateDBCluster operation that is called in the destination AWS Region, and the operation contained in the presigned URL.
DestinationRegion - The name of the AWS Region that Aurora read replica will be created in.
ReplicationSourceIdentifier - The DB cluster identifier for the encrypted DB cluster to be copied. This identifier must be in the Amazon Resource Name (ARN) format for the source AWS Region. For example, if you are copying an encrypted DB cluster from the us-west-2 AWS Region, then your ReplicationSourceIdentifier would look like Example: arn:aws:rds:us-west-2:123456789012:cluster:aurora-cluster1.

To learn how to generate a Signature Version 4 signed request, see Authenticating Requests: Using Query Parameters (AWS Signature Version 4) and Signature Version 4 Signing Process.

Note

If you are using an AWS SDK tool or the AWS CLI, you can specify SourceRegion (or --source-region for the AWS CLI) instead of specifying PreSignedUrl manually. Specifying SourceRegion autogenerates a presigned URL that is a valid request for the operation that can run in the source AWS Region.

Valid for Cluster Type: Aurora DB clusters only

Type: String

Required: No

PubliclyAccessible

Specifies whether the DB cluster is publicly accessible.

When the DB cluster is publicly accessible and you connect from outside of the DB cluster's virtual private cloud (VPC), its Domain Name System (DNS) endpoint resolves to the public IP address. When you connect from within the same VPC as the DB cluster, the endpoint resolves to the private IP address. Access to the DB cluster is ultimately controlled by the security group it uses. That public access isn't permitted if the security group assigned to the DB cluster doesn't permit it.

When the DB cluster isn't publicly accessible, it is an internal DB cluster with a DNS name that resolves to a private IP address.

Valid for Cluster Type: Multi-AZ DB clusters only

Default: The default behavior varies depending on whether DBSubnetGroupName is specified.

If DBSubnetGroupName isn't specified, and PubliclyAccessible isn't specified, the following applies:

If the default VPC in the target Region doesn’t have an internet gateway attached to it, the DB cluster is private.
If the default VPC in the target Region has an internet gateway attached to it, the DB cluster is public.

If DBSubnetGroupName is specified, and PubliclyAccessible isn't specified, the following applies:

If the subnets are part of a VPC that doesn’t have an internet gateway attached to it, the DB cluster is private.
If the subnets are part of a VPC that has an internet gateway attached to it, the DB cluster is public.
