AWS::DMS::ReplicationInstance

The AWS::DMS::ReplicationInstance resource creates an AWS DMS replication instance. To create a ReplicationInstance, you need permissions to create instances. You'll need similar permissions to terminate instances when you delete stacks with instances.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

Properties

AllocatedStorage

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

Required: No

Type: Integer

Update requires: No interruption

AllowMajorVersionUpgrade

Indicates that major version upgrades are allowed. Changing this parameter does not result in an outage, and the change is asynchronously applied as soon as possible.

This parameter must be set to true when specifying a value for the EngineVersion parameter that is a different major version than the replication instance's current version.

Required: No

Type: Boolean

Update requires: No interruption

AutoMinorVersionUpgrade

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

Required: No

Type: Boolean

Update requires: No interruption

AvailabilityZone

The Availability Zone that the replication instance will be created in.

The default value is a random, system-chosen Availability Zone in the endpoint's AWS Region, for example us-east-1d.

Required: No

Type: String

Update requires: No interruption

DnsNameServers

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"

Required: No

Type: String

Update requires: Replacement

EngineVersion

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.

Required: No

Type: String

Update requires: No interruption

KmsKeyId

An AWS 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, AWS DMS 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.

Required: No

Type: String

Update requires: Replacement

MultiAZ

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.

Required: No

Type: Boolean

Update requires: No interruption

NetworkType

The type of IP address protocol used by a replication instance, such as IPv4 only or Dual-stack that supports both IPv4 and IPv6 addressing. IPv6 only is not yet supported.

Required: No

Type: String

Update requires: No interruption

PreferredMaintenanceWindow

The weekly time range during which system maintenance can occur, in UTC.

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

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

Valid days (ddd): Mon | Tue | Wed | Thu | Fri | Sat | Sun

Constraints: Minimum 30-minute window.

Required: No

Type: String

Update requires: No interruption

PubliclyAccessible

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.

Required: No

Type: Boolean

Update requires: Replacement

ReplicationInstanceClass

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 AWS DMS replication instance for your migration in the AWS Database Migration Service User Guide.

Required: Yes

Type: String

Maximum: 30

Update requires: No interruption

ReplicationInstanceIdentifier

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

Required: No

Type: String

Update requires: No interruption

ReplicationSubnetGroupIdentifier

A subnet group to associate with the replication instance.

Required: No

Type: String

Update requires: Replacement

ResourceIdentifier

A display 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, AWS DMS generates a default identifier value for the end of EndpointArn.

Required: No

Type: String

Update requires: Replacement

Tags

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

Required: No

Type: Array of Tag

Update requires: No interruption

VpcSecurityGroupIds

Specifies the virtual private cloud (VPC) security group to be used with the replication instance. The VPC security group must work with the VPC containing the replication instance.

Required: No

Type: Array of String

Update requires: No interruption

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the replication instance ARN.

For more information about using the Ref function, see Ref.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.

ReplicationInstancePrivateIpAddresses

One or more private IP addresses for the replication instance.

ReplicationInstancePublicIpAddresses

One or more public IP addresses for the replication instance.
