[ aws . redshift ]



Modifies a cluster subnet group to include the specified list of VPC subnets. The operation replaces the existing list of subnets with the new list of subnets.

See ‘aws help’ for descriptions of global parameters.

--subnet-ids <value>

--cluster-subnet-group-name (string)

The name of the subnet group to be modified.

--description (string)

A text description of the subnet group to be modified.

--subnet-ids (list)

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

--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.


Modify the Subnets in a Cluster Subnet Group

This example shows how to modify the list of subnets in a cache subnet group. By default, the output is in JSON format.
