create-replication-instance

Description

Creates the replication instance using the specified parameters.

DMS requires that your account have certain roles with appropriate permissions before you can create a replication instance. For information on the required roles, see Creating the IAM Roles to Use With the CLI and DMS API . For information on the required permissions, see IAM Permissions Needed to Use DMS .

Options

--replication-instance-identifier (string)

The replication instance identifier. This parameter is stored as a lowercase string.

Constraints:

• Must contain 1-63 alphanumeric characters or hyphens.

• First character must be a letter.

• Can’t end with a hyphen or contain two consecutive hyphens.

Example: myrepinstance

--allocated-storage (integer)

The amount of storage (in gigabytes) to be initially allocated for the replication instance.

--replication-instance-class (string)

The compute and memory capacity of the replication instance as defined for the specified replication instance class. For example to specify the instance class dms.c4.large, set this parameter to "dms.c4.large" .

For more information on the settings and capacities for the available replication instance classes, see Selecting the right DMS replication instance for your migration .

--vpc-security-group-ids (list)

Specifies the VPC security group to be used with the replication instance. The VPC security group must work with the VPC containing the replication instance.

(string)

Syntax:

"string" "string" ...

--availability-zone (string)

The Availability Zone where the replication instance will be created. The default value is a random, system-chosen Availability Zone in the endpoint’s Amazon Web Services Region, for example: us-east-1d

--replication-subnet-group-identifier (string)

A subnet group to associate with the replication instance.

--preferred-maintenance-window (string)

The weekly time range during which system maintenance can occur, in Universal Coordinated Time (UTC).

Format: ddd:hh24:mi-ddd:hh24:mi

Default: A 30-minute window selected at random from an 8-hour block of time per Amazon Web Services Region, occurring on a random day of the week.

Valid Days: Mon, Tue, Wed, Thu, Fri, Sat, Sun

Constraints: Minimum 30-minute window.

--multi-az | --no-multi-az (boolean)

Specifies whether the replication instance is a Multi-AZ deployment. You can’t set the AvailabilityZone parameter if the Multi-AZ parameter is set to true .

--engine-version (string)

The engine version number of the replication instance.

If an engine version number is not specified when a replication instance is created, the default is the latest engine version available.

--auto-minor-version-upgrade | --no-auto-minor-version-upgrade (boolean)

A value that indicates whether minor engine upgrades are applied automatically to the replication instance during the maintenance window. This parameter defaults to true .

Default: true

--tags (list)

One or more tags to be assigned to the replication instance.

(structure)

A user-defined key-value pair that describes metadata added to an DMS resource and that is used by operations such as the following:

• AddTagsToResource

• ListTagsForResource

• RemoveTagsFromResource

Key -> (string)

A key is the required name of the tag. The string value can be 1-128 Unicode characters in length and can’t be prefixed with “aws:” or “dms:”. The string can only contain only the set of Unicode letters, digits, white-space, ‘_’, ‘.’, ‘/’, ‘=’, ‘+’, ‘-‘ (Java regular expressions: “^([\p{L}\p{Z}\p{N}_.:/=+-]*)$”).

Value -> (string)

A value is the optional value of the tag. The string value can be 1-256 Unicode characters in length and can’t be prefixed with “aws:” or “dms:”. The string can only contain only the set of Unicode letters, digits, white-space, ‘_’, ‘.’, ‘/’, ‘=’, ‘+’, ‘-‘ (Java regular expressions: “^([\p{L}\p{Z}\p{N}_.:/=+-]*)$”).

ResourceArn -> (string)

The Amazon Resource Name (ARN) string that uniquely identifies the resource for which the tag is created.

Shorthand Syntax:

Key=string,Value=string,ResourceArn=string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Value": "string",
    "ResourceArn": "string"
  }
  ...
]

--kms-key-id (string)

An KMS key identifier that is used to encrypt the data on the replication instance.

If you don’t specify a value for the KmsKeyId parameter, then DMS uses your default encryption key.

KMS creates the default encryption key for your Amazon Web Services account. Your Amazon Web Services account has a different default encryption key for each Amazon Web Services Region.

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

Specifies the accessibility options for the replication instance. A value of true represents an instance with a public IP address. A value of false represents an instance with a private IP address. The default value is true .

--dns-name-servers (string)

A list of custom DNS name servers supported for the replication instance to access your on-premise source or target database. This list overrides the default name servers supported by the replication instance. You can specify a comma-separated list of internet addresses for up to four on-premise DNS name servers. For example: "1.1.1.1,2.2.2.2,3.3.3.3,4.4.4.4"

--resource-identifier (string)

A friendly name for the resource identifier at the end of the EndpointArn response parameter that is returned in the created Endpoint object. The value for this parameter can have up to 31 characters. It can contain only ASCII letters, digits, and hyphen (‘-‘). Also, it can’t end with a hyphen or contain two consecutive hyphens, and can only begin with a letter, such as Example-App-ARN1 . For example, this value might result in the EndpointArn value arn:aws:dms:eu-west-1:012345678901:rep:Example-App-ARN1 . If you don’t specify a ResourceIdentifier value, DMS generates a default identifier value for the end of EndpointArn .

--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.

See ‘aws help’ for descriptions of global parameters.
