modify-db-subnet-group

Description

Modifies an existing subnet group. subnet groups must contain at least one subnet in at least two Availability Zones in the AWS Region.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  modify-db-subnet-group
--db-subnet-group-name <value>
[--db-subnet-group-description <value>]
--subnet-ids <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--db-subnet-group-name (string)

The name for the subnet group. This value is stored as a lowercase string. You can't modify the default subnet group.

Constraints: Must match the name of an existing DBSubnetGroup . Must not be default.

Example: mySubnetgroup

--db-subnet-group-description (string)

The description for the subnet group.

--subnet-ids (list)

The Amazon EC2 subnet IDs for the subnet group.

Syntax:

"string" "string" ...

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. 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.

Examples

To modify an Amazon DocumentDB subnet group

The following modify-db-subnet-group example modifies the subnet group sample-subnet-group by adding the specified subnets and a new description.

aws docdb modify-db-subnet-group \
    --db-subnet-group-name sample-subnet-group \
    --subnet-ids subnet-b3806e8f subnet-53ab3636 subnet-991cb8d0 \
    --db-subnet-group-description "New subnet description"

Output:

{
    "DBSubnetGroup": {
        "DBSubnetGroupName": "sample-subnet-group",
        "SubnetGroupStatus": "Complete",
        "DBSubnetGroupArn": "arn:aws:rds:us-west-2:123456789012:subgrp:sample-subnet-group",
        "VpcId": "vpc-91280df6",
        "DBSubnetGroupDescription": "New subnet description",
        "Subnets": [
            {
                "SubnetIdentifier": "subnet-b3806e8f",
                "SubnetStatus": "Active",
                "SubnetAvailabilityZone": {
                    "Name": "us-west-2a"
                }
            },
            {
                "SubnetIdentifier": "subnet-53ab3636",
                "SubnetStatus": "Active",
                "SubnetAvailabilityZone": {
                    "Name": "us-west-2c"
                }
            },
            {
                "SubnetIdentifier": "subnet-991cb8d0",
                "SubnetStatus": "Active",
                "SubnetAvailabilityZone": {
                    "Name": "us-west-2b"
                }
            }
        ]
    }
