describe-vpc-attribute

Description

Describes the specified attribute of the specified VPC. You can specify only one attribute at a time.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  describe-vpc-attribute
--attribute <value>
--vpc-id <value>
[--dry-run | --no-dry-run]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--attribute (string)

The VPC attribute.

Possible values:

• enableDnsSupport

• enableDnsHostnames

--vpc-id (string)

The ID of the VPC.

--dry-run | --no-dry-run (boolean)

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To describe the enableDnsSupport attribute

This example describes the enableDnsSupport attribute. This attribute indicates whether DNS resolution is enabled for the VPC. If this attribute is true, the Amazon DNS server resolves DNS hostnames for your instances to their corresponding IP addresses; otherwise, it does not.

Command:

aws ec2 describe-vpc-attribute --vpc-id vpc-a01106c2 --attribute enableDnsSupport

Output:

{
    "VpcId": "vpc-a01106c2",
    "EnableDnsSupport": {
        "Value": true
    }
}

To describe the enableDnsHostnames attribute

This example describes the enableDnsHostnames attribute. This attribute indicates whether the instances launched in the VPC get DNS hostnames. If this attribute is true, instances in the VPC get DNS hostnames; otherwise, they do not.

Command:

aws ec2 describe-vpc-attribute --vpc-id vpc-a01106c2 --attribute enableDnsHostnames

Output:

{
    "VpcId": "vpc-a01106c2",
    "EnableDnsHostnames": {
        "Value": true
    }
}

Output

VpcId -> (string)

The ID of the VPC.

EnableDnsHostnames -> (structure)

Indicates whether the instances launched in the VPC get DNS hostnames. If this attribute is true , instances in the VPC get DNS hostnames; otherwise, they do not.

Value -> (boolean)

The attribute value. The valid values are true or false .

EnableDnsSupport -> (structure)

Indicates whether DNS resolution is enabled for the VPC. If this attribute is true , the Amazon DNS server resolves DNS hostnames for your instances to their corresponding IP addresses; otherwise, it does not.

Value -> (boolean)

The attribute value. The valid values are true or false .
