describe-principal-id-format

Description

Describes the ID format settings for the root user and all IAM roles and IAM users that have explicitly specified a longer ID (17-character ID) preference.

By default, all IAM roles and IAM users default to the same ID settings as the root user, unless they explicitly override the settings. This request is useful for identifying those IAM users and IAM roles that have overridden the default ID settings.

The following resource types support longer IDs: bundle | conversion-task | customer-gateway | dhcp-options | elastic-ip-allocation | elastic-ip-association | export-task | flow-log | image | import-task | instance | internet-gateway | network-acl | network-acl-association | network-interface | network-interface-attachment | prefix-list | reservation | route-table | route-table-association | security-group | snapshot | subnet | subnet-cidr-block-association | volume | vpc | vpc-cidr-block-association | vpc-endpoint | vpc-peering-connection | vpn-connection | vpn-gateway .

describe-principal-id-format 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: Principals

Synopsis

  describe-principal-id-format
[--dry-run | --no-dry-run]
[--resources <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--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 .

--resources (list)

The type of resource: bundle | conversion-task | customer-gateway | dhcp-options | elastic-ip-allocation | elastic-ip-association | export-task | flow-log | image | import-task | instance | internet-gateway | network-acl | network-acl-association | network-interface | network-interface-attachment | prefix-list | reservation | route-table | route-table-association | security-group | snapshot | subnet | subnet-cidr-block-association | volume | vpc | vpc-cidr-block-association | vpc-endpoint | vpc-peering-connection | vpn-connection | vpn-gateway

(string)

Syntax:

"string" "string" ...

--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 describe the ID format for IAM users and roles with long ID format enabled

The following describe-principal-id-format example describes the ID format for the root user, all IAM roles, and all IAM users with long ID format enabled.

aws ec2 describe-principal-id-format \
    --resource instance

Output:

{
    "Principals": [
        {
            "Arn": "arn:aws:iam::123456789012:root",
            "Statuses": [
                {
                    "Deadline": "2016-12-15T00:00:00.000Z",
                    "Resource": "reservation",
                    "UseLongIds": true
                },
                {
                    "Deadline": "2016-12-15T00:00:00.000Z",
                    "Resource": "instance",
                    "UseLongIds": true
                },
                {
                    "Deadline": "2016-12-15T00:00:00.000Z",
                    "Resource": "volume",
                    "UseLongIds": true
                },
            ]
        },

Arn -> (string)

PrincipalIdFormatARN description

Statuses -> (list)

PrincipalIdFormatStatuses description

(structure)

Describes the ID format for a resource.

Deadline -> (timestamp)

The date in UTC at which you are permanently switched over to using longer IDs. If a deadline is not yet available for this resource type, this field is not returned.

Resource -> (string)

The type of resource.

UseLongIds -> (boolean)

Indicates whether longer IDs (17-character IDs) are enabled for the resource.

NextToken -> (string)
