RDS / Client / create_db_cluster

create_db_cluster#

RDS.Client.create_db_cluster(**kwargs)#

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.

- (dict) –
  
  Metadata assigned to an Amazon RDS resource consisting of a key-value pair.
  
  For more information, see Tagging Amazon RDS Resources in the Amazon RDS User Guide.
  - Key (string) –
    
    A key is the required name of the tag. The string value can be from 1 to 128 Unicode characters in length and can’t be prefixed with aws: or rds:. The string can only contain only the set of Unicode letters, digits, white-space, ‘_’, ‘.’, ‘:’, ‘/’, ‘=’, ‘+’, ‘-’, ‘@’ (Java regex: “^([\p{L}\p{Z}\p{N}_.:/=+\-@]*)$”).

StorageEncrypted (boolean) –
A value that indicates whether the DB cluster is encrypted.

Valid for: Aurora DB clusters and Multi-AZ DB clusters
KmsKeyId (string) –
The Amazon Web Services KMS key identifier for an encrypted DB cluster.

The Amazon Web Services 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 Amazon Web Services 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 will use the KMS key used to encrypt the source. Otherwise, Amazon RDS will use your default KMS key.
- If the StorageEncrypted parameter is enabled and ReplicationSourceIdentifier isn’t specified, then Amazon RDS will use your default KMS key.
There is a default KMS key for your Amazon Web Services account. Your Amazon Web Services account has a different default KMS key for each Amazon Web Services Region.

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

Valid for: Aurora DB clusters and Multi-AZ DB clusters
PreSignedUrl (string) –
When you are replicating a DB cluster from one Amazon Web Services 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 Amazon Web Services 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 Amazon Web Services Region that contains the encrypted DB cluster to copy.

The presigned URL request must contain the following parameter values:
- KmsKeyId - The KMS key identifier for the KMS key to use to encrypt the copy of the DB cluster in the destination Amazon Web Services Region. This should refer to the same KMS key for both the CreateDBCluster operation that is called in the destination Amazon Web Services Region, and the operation contained in the presigned URL.
- DestinationRegion - The name of the Amazon Web Services 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 Amazon Web Services Region. For example, if you are copying an encrypted DB cluster from the us-west-2 Amazon Web Services 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 (Amazon Web Services Signature Version 4) and Signature Version 4 Signing Process.

Note
If you are using an Amazon Web Services SDK tool or the CLI, you can specify SourceRegion (or --source-region for the 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 Amazon Web Services Region.

Valid for: Aurora DB clusters only

Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required
EnableIAMDatabaseAuthentication (boolean) –

You can set this value only on Aurora DB clusters that are members of an Aurora global database. With this parameter enabled, a secondary cluster can forward writes to the current primary cluster and the resulting changes are replicated back to this cluster. For the primary DB cluster of an Aurora global database, this value is used immediately if the primary is demoted by the FailoverGlobalCluster API operation, but it does nothing until then.

Valid for: Aurora DB clusters only
DBClusterInstanceClass (string) –
The compute and memory capacity of each DB instance in the Multi-AZ DB cluster, for example db.m6gd.xlarge. Not all DB instance classes are available in all Amazon Web Services Regions, or for all database engines.

Constraints: Must be a multiple between .5 and 50 of the storage amount for the DB cluster.

Valid for: Multi-AZ DB clusters only
PubliclyAccessible (boolean) –
A value that indicates whether the DB cluster is publicly accessible.

When the DB cluster is publicly accessible, its Domain Name System (DNS) endpoint resolves to the private IP address from within the DB cluster’s virtual private cloud (VPC). It resolves to the public IP address from outside of the DB cluster’s VPC. 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.

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.
Valid for: Multi-AZ DB clusters only

Valid for: Aurora DB clusters and Multi-AZ DB clusters
MasterUserSecretKmsKeyId (string) –
The Amazon Web Services KMS key identifier to encrypt a secret that is automatically generated and managed in Amazon Web Services Secrets Manager.

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

The Amazon Web Services 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 Amazon Web Services 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 Amazon Web Services 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 Amazon Web Services account. Your Amazon Web Services account has a different default KMS key for each Amazon Web Services Region.

  - PerformanceInsightsEnabled (boolean) –
    
    True if Performance Insights is enabled for the DB cluster, and otherwise false.
    
    This setting is only for non-Aurora Multi-AZ DB clusters.
  - PerformanceInsightsKMSKeyId (string) –
    
    The Amazon Web Services KMS key identifier for encryption of Performance Insights data.
    
    The Amazon Web Services KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key.
    
    This setting is only for non-Aurora Multi-AZ DB clusters.
  - PerformanceInsightsRetentionPeriod (integer) –
    
    The number of days to retain Performance Insights data. The default is 7 days. The following values are valid:
    - 7
    - month * 31, where month is a number of months from 1-23
    - 731
    For example, the following values are valid:
    - 93 (3 months * 31)
    - 341 (11 months * 31)
    - 589 (19 months * 31)
    - 731
    This setting is only for non-Aurora Multi-AZ DB clusters.
  - ServerlessV2ScalingConfiguration (dict) –
    
    Shows the scaling configuration for an Aurora Serverless v2 DB cluster.
    
    For more information, see Using Amazon Aurora Serverless v2 in the Amazon Aurora User Guide.
    - MinCapacity (float) –
      
      The minimum number of Aurora capacity units (ACUs) for a DB instance in an Aurora Serverless v2 cluster. You can specify ACU values in half-step increments, such as 8, 8.5, 9, and so on. The smallest value that you can use is 0.5.
    - MaxCapacity (float) –
      
      The maximum number of Aurora capacity units (ACUs) for a DB instance in an Aurora Serverless v2 cluster. You can specify ACU values in half-step increments, such as 40, 40.5, 41, and so on. The largest value that you can use is 128.
  - NetworkType (string) –
    
    The network type of the DB instance.
    
    Valid values:
    - IPV4
    - DUAL
    The network type is determined by the DBSubnetGroup specified for the DB cluster. A DBSubnetGroup can support only the IPv4 protocol or the IPv4 and the IPv6 protocols ( DUAL).
    
    For more information, see Working with a DB instance in a VPC in the Amazon Aurora User Guide.
    
    This setting is only for Aurora DB clusters.
  - DBSystemId (string) –
    
    Reserved for future use.
  - MasterUserSecret (dict) –
    
    Contains the secret managed by RDS in Amazon Web Services Secrets Manager for the master user password.
    
    For more information, see Password management with Amazon Web Services Secrets Manager in the Amazon RDS User Guide and Password management with Amazon Web Services Secrets Manager in the Amazon Aurora User Guide.
    - SecretArn (string) –
      
      The Amazon Resource Name (ARN) of the secret.
    - SecretStatus (string) –
      
      The status of the secret.
      
      The possible status values include the following:
      - creating - The secret is being created.
      - active - The secret is available for normal use and rotation.
      - rotating - The secret is being rotated.
      - impaired - The secret can be used to access database credentials, but it can’t be rotated. A secret might have this status if, for example, permissions are changed so that RDS can no longer access either the secret or the KMS key for the secret. When a secret has this status, you can correct the condition that caused the status. Alternatively, modify the DB instance to turn off automatic management of database credentials, and then modify the DB instance again to turn on automatic management of database credentials.
    - KmsKeyId (string) –
      
      The Amazon Web Services KMS key identifier that is used to encrypt the secret.
  - IOOptimizedNextAllowedModificationTime (datetime) –
    
    The next time you can modify the DB cluster to use the aurora-iopt1 storage type.
    
    This setting is only for Aurora DB clusters.
