--publicly-accessible | --no-publicly-accessible (boolean)

A value that indicates whether the DB instance is publicly accessible.

When the DB instance is publicly accessible, its DNS endpoint resolves to the private IP address from within the DB instance’s VPC, and 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, and 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:

  • If the subnets are part of a VPC that doesn’t have an Internet gateway attached to it, the DB instance is private.

  • If the subnets are part of a VPC that has an Internet gateway attached to it, the DB instance is public.

--tags (list)

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}_.:/=+-]*)$”).

Value -> (string)

A value is the optional value of the tag. The string value can be from 1 to 256 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}_.:/=+-]*)$”).

Amazon Aurora

Not applicable. The encryption for DB instances is managed by the DB cluster.

--kms-key-id (string)

The AWS KMS key identifier for an encrypted DB instance.

The KMS key identifier is the Amazon Resource Name (ARN) for the KMS encryption key. If you are creating a DB instance with the same AWS account that owns the KMS encryption key used to encrypt the new DB instance, then you can use the KMS key alias instead of the ARN for the KM encryption key.

Amazon Aurora

Not applicable. The 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 will use your default encryption key. AWS KMS creates the default encryption key for your AWS account. Your AWS account has a different default encryption key for each AWS Region.

--domain (string)

The Active Directory directory ID to create the DB instance in. Currently, only Microsoft SQL Server and Oracle DB instances can be created in an Active Directory Domain.

For Microsoft SQL Server DB instances, Amazon RDS can use Windows Authentication to authenticate users that connect to the DB instance. For more information, see Using Windows Authentication with an Amazon RDS DB Instance Running Microsoft SQL Server in the Amazon RDS User Guide .

For Oracle DB instances, Amazon RDS can use Kerberos Authentication to authenticate users that connect to the DB instance. For more information, see Using Kerberos Authentication with Amazon RDS for Oracle in the Amazon RDS User Guide .

--copy-tags-to-snapshot | --no-copy-tags-to-snapshot (boolean)

A value that indicates whether to copy tags from the DB instance to snapshots of the DB instance. By default, tags are not copied.

--monitoring-interval (integer)

The interval, in seconds, between points when Enhanced Monitoring metrics are collected for the DB instance. To disable collecting Enhanced Monitoring metrics, specify 0. The default is 0.

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

Valid Values: 0, 1, 5, 10, 15, 30, 60

--monitoring-role-arn (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, go to 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.

--domain-iam-role-name (string)

Specify the name of the IAM role to be used when making API calls to the Directory Service.

--promotion-tier (integer)

A value that specifies the order in which an Aurora Replica is promoted to the primary instance after a failure of the existing primary instance. For more information, see Fault Tolerance for an Aurora DB Cluster in the Amazon Aurora User Guide .

Default: 1

Valid Values: 0 - 15

A value that indicates whether to enable Performance Insights for the DB instance.

For more information, see Using Amazon Performance Insights in the Amazon Relational Database Service User Guide .

--performance-insights-kms-key-id (string)

The AWS KMS key identifier for encryption of Performance Insights data. 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 do not specify a value for PerformanceInsightsKMSKeyId , then Amazon RDS uses your default encryption key. AWS KMS creates the default encryption key for your AWS account. Your AWS account has a different default encryption key for each AWS Region.

--performance-insights-retention-period (integer)

The amount of time, in days, to retain Performance Insights data. Valid values are 7 or 731 (2 years).

--enable-cloudwatch-logs-exports (list)

Syntax:

"string" "string" ...

--processor-features (list)

The number of CPU cores and the number of threads per core for the DB instance class of the DB instance.

(structure)

Contains the processor features of a DB instance class.

To specify the number of CPU cores, use the coreCount feature name for the Name parameter. To specify the number of threads per core, use the threadsPerCore feature name for the Name parameter.

You can set the processor features of the DB instance class for a DB instance when you call one of the following actions:

  • CreateDBInstance

  • ModifyDBInstance

  • RestoreDBInstanceFromDBSnapshot

  • RestoreDBInstanceFromS3

  • RestoreDBInstanceToPointInTime

You can view the valid processor values for a particular instance class by calling the DescribeOrderableDBInstanceOptions action and specifying the instance class for the DBInstanceClass parameter.

In addition, you can use the following actions for DB instance class processor information:

  • DescribeDBInstances

  • DescribeDBSnapshots

  • DescribeValidDBInstanceModifications

For more information, see Configuring the Processor of the DB Instance Class in the Amazon RDS User Guide.

Name -> (string)

The name of the processor feature. Valid names are coreCount and threadsPerCore .

Value -> (string)

The value of a processor feature name.

  }
  ...
]

--max-allocated-storage (integer)

The upper limit to which Amazon RDS can automatically scale the storage of the DB instance.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.
