create_db_instance#

RDS.Client.create_db_instance(**kwargs)#

Creates a new DB instance.

The new DB instance can be an RDS DB instance, or it can be a DB instance in an Aurora DB cluster. For an Aurora DB cluster, you can call this operation multiple times to add more than one DB instance to the cluster.

For more information about creating an RDS DB instance, see Creating an Amazon RDS DB instance in the Amazon RDS User Guide.

For more information about creating a DB instance in an Aurora DB cluster, see Creating an Amazon Aurora DB cluster in the Amazon Aurora User Guide.

PubliclyAccessible (boolean) –
A value that indicates whether the DB instance is publicly accessible.

When the DB instance is publicly accessible, its Domain Name System (DNS) endpoint resolves to the private IP address from within the DB instance’s virtual private cloud (VPC). It resolves to the public IP address from outside of the DB instance’s VPC. Access to the DB instance is ultimately controlled by the security group it uses. That public access is not permitted if the security group assigned to the DB instance doesn’t permit it.

When the DB instance isn’t publicly accessible, it is an internal DB instance 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 instance is private.
- If the default VPC in the target Region has an internet gateway attached to it, the DB instance is public.
If DBSubnetGroupName is specified, and PubliclyAccessible isn’t specified, the following applies:

Amazon Aurora

Not applicable. The encryption for DB instances is managed by the DB cluster.
KmsKeyId (string) –
The Amazon Web Services KMS key identifier for an encrypted DB instance.

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.

Amazon Aurora

Not applicable. The Amazon Web Services KMS key identifier is managed by the DB cluster. For more information, see CreateDBCluster.

If StorageEncrypted is enabled, and you do not specify a value for the KmsKeyId parameter, then Amazon RDS uses 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.

Amazon RDS Custom

A KMS key is required for RDS Custom instances. For most RDS engines, if you leave this parameter empty while enabling StorageEncrypted, the engine uses the default KMS key. However, RDS Custom doesn’t use the default key when this parameter is empty. You must explicitly specify a key.

Valid Values: 0, 1, 5, 10, 15, 30, 60
MonitoringRoleArn (string) –
The ARN for the IAM role that permits RDS to send enhanced monitoring metrics to Amazon CloudWatch Logs. For example, arn:aws:iam:123456789012:role/emaccess. For information on creating a monitoring role, see Setting Up and Enabling Enhanced Monitoring in the Amazon RDS User Guide.

If MonitoringInterval is set to a value other than 0, then you must supply a MonitoringRoleArn value.

This setting doesn’t apply to RDS Custom.

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.

If you do not specify a value for PerformanceInsightsKMSKeyId, then Amazon RDS uses 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.

This setting doesn’t apply to RDS Custom.
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

For example, the following values are valid:
- 93 (3 months * 31)
- 341 (11 months * 31)
- 589 (19 months * 31)

Amazon Aurora

Not applicable. You can enable or disable deletion protection for the DB cluster. For more information, see CreateDBCluster. DB instances in a DB cluster can be deleted even when deletion protection is enabled for the DB cluster.
MaxAllocatedStorage (integer) –
The upper limit in gibibytes (GiB) to which Amazon RDS can automatically scale the storage of the DB instance.

For more information about this setting, including limitations that apply to it, see Managing capacity automatically with Amazon RDS storage autoscaling in the Amazon RDS User Guide.

This setting doesn’t apply to RDS Custom.

Amazon Aurora

Not applicable. Storage is managed by the DB cluster.
EnableCustomerOwnedIp (boolean) –
A value that indicates whether to enable a customer-owned IP address (CoIP) for an RDS on Outposts DB instance.

A CoIP provides local or external connectivity to resources in your Outpost subnets through your on-premises network. For some use cases, a CoIP can provide lower latency for connections to the DB instance from outside of its virtual private cloud (VPC) on your local network.

For more information about RDS on Outposts, see Working with Amazon RDS on Amazon Web Services Outposts in the Amazon RDS User Guide.

For more information about CoIPs, see Customer-owned IP addresses in the Amazon Web Services Outposts User Guide.
CustomIamInstanceProfile (string) –
The instance profile associated with the underlying Amazon EC2 instance of an RDS Custom DB instance. The instance profile must meet the following requirements:
- The profile must exist in your account.
- The profile must have an IAM role that Amazon EC2 has permissions to assume.
- The instance profile name and the associated IAM role name must start with the prefix AWSRDSCustom.
For the list of permissions required for the IAM role, see Configure IAM and your VPC in the Amazon RDS User Guide.

This setting is required for RDS Custom.
BackupTarget (string) –
Specifies where automated backups and manual snapshots are stored.

Possible values are outposts (Amazon Web Services Outposts) and region (Amazon Web Services Region). The default is region.

For more information, see Working with Amazon RDS on Amazon Web Services Outposts in the Amazon RDS User Guide.
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 instance. 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 RDS User Guide.
StorageThroughput (integer) –
Specifies the storage throughput value for the DB instance.

This setting applies only to the gp3 storage type.

This setting doesn’t apply to RDS Custom or Amazon Aurora.
ManageMasterUserPassword (boolean) –
A value that indicates whether to manage the master user password with Amazon Web Services Secrets Manager.

For more information, see Password management with Amazon Web Services Secrets Manager in the Amazon RDS User Guide.

Constraints:
- Can’t manage the master user password with Amazon Web Services Secrets Manager if MasterUserPassword is specified.
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 instance.

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.
CACertificateIdentifier (string) –
Specifies the CA certificate identifier to use for the DB instance’s server certificate.

This setting doesn’t apply to RDS Custom.

For more information, see Using SSL/TLS to encrypt a connection to a DB instance in the Amazon RDS User Guide and Using SSL/TLS to encrypt a connection to a DB cluster in the Amazon Aurora User Guide.
