list-firewall-configs

Description

Retrieves the firewall configurations that you have defined. DNS Firewall uses the configurations to manage firewall behavior for your VPCs.

A single call might return only a partial list of the configurations. For information, see MaxResults .

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

list-firewall-configs is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: FirewallConfigs

Synopsis

  list-firewall-configs
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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.

See ‘aws help’ for descriptions of global parameters.

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 list firewall configs

The following list-firewall-configs example lists your DNS Firewall configurations.

aws route53resolver list-firewall-configs

Output:

{
    "FirewallConfigs": [
        {
            "Id": "rslvr-fc-86016850cexample",
            "ResourceId": "vpc-31e92222",
            "OwnerId": "123456789012",
            "FirewallFailOpen": "DISABLED"
        }
    ]
}

For more information, see DNS Firewall VPC configuration in the Amazon Route 53 Developer Guide.

Output

NextToken -> (string)

If objects are still available for retrieval, Resolver returns this token in the response. To retrieve the next batch of objects, provide this token in your next request.

FirewallConfigs -> (list)

The configurations for the firewall behavior provided by DNS Firewall for VPCs from Amazon Virtual Private Cloud (Amazon VPC).

(structure)

Configuration of the firewall behavior provided by DNS Firewall for a single VPC from Amazon Virtual Private Cloud (Amazon VPC).

Id -> (string)

The ID of the firewall configuration.

ResourceId -> (string)

The ID of the VPC that this firewall configuration applies to.

OwnerId -> (string)

The Amazon Web Services account ID of the owner of the VPC that this firewall configuration applies to.

FirewallFailOpen -> (string)

Determines how DNS Firewall operates during failures, for example when all traffic that is sent to DNS Firewall fails to receive a reply.

• By default, fail open is disabled, which means the failure mode is closed. This approach favors security over availability. DNS Firewall returns a failure error when it is unable to properly evaluate a query.

• If you enable this option, the failure mode is open. This approach favors availability over security. DNS Firewall allows queries to proceed if it is unable to properly evaluate them.

This behavior is only enforced for VPCs that have at least one DNS Firewall rule group association.
