Specifies an Amazon Redshift subnet group. You must provide a list of one or more subnets in your existing Amazon Virtual Private Cloud (Amazon VPC) when creating Amazon Redshift subnet group.

For information about subnet groups, go to Amazon Redshift Cluster Subnet Groups in the Amazon Redshift Cluster Management Guide.


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


{ "Type" : "AWS::Redshift::ClusterSubnetGroup", "Properties" : { "Description" : String, "SubnetIds" : [ String, ... ], "Tags" : [ Tag, ... ] } }


Type: AWS::Redshift::ClusterSubnetGroup Properties: Description: String SubnetIds: - String Tags: - Tag



A description for the subnet group.

Required: Yes

Type: String

Maximum: 2147483647

Update requires: No interruption


An array of VPC subnet IDs. A maximum of 20 subnets can be modified in a single request.

Required: Yes

Type: Array of String

Return values


When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the resource name. For example:

{ "Ref": "myClusterSubnetGroup" }

For the Amazon Redshift subnet group myClusterSubnetGroup, Ref returns the name of the cluster subnet group.

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


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.


The name of the cluster subnet group.


Specify a Subnet

The following example specifies one subnet for an Amazon Redshift cluster subnet group.


"myClusterSubnetGroup": { "Type": "AWS::Redshift::ClusterSubnetGroup", "Properties": { "Description": "My ClusterSubnetGroup", "SubnetIds": [ "subnet-7fbc2813" ], "Tags": [ { "Key": "foo", "Value": "bar" } ] } }


myClusterSubnetGroup: Type: 'AWS::Redshift::ClusterSubnetGroup' Properties: Description: My ClusterSubnetGroup SubnetIds: - subnet-7fbc2813 Tags: - Key: foo Value: bar
