list-group-resources

Description

Returns a list of ARNs of the resources that are members of a specified resource group.

Minimum permissions

To run this command, you must have the following permissions:

• resource-groups:ListGroupResources

• cloudformation:DescribeStacks

• cloudformation:ListStackResources

• tag:GetResources

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

list-group-resources 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: ResourceIdentifiers, Resources

Synopsis

  list-group-resources
[--group-name <value>]
[--group <value>]
[--filters <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--group-name (string)

Warning

• Deprecated - don’t use this parameter. Use the ``Group`` request field instead. *

--group (string)

The name or the ARN of the resource group

--filters (list)

Filters, formatted as ResourceFilter objects, that you want to apply to a ListGroupResources operation. Filters the results to include only those of the specified resource types.

• resource-type - Filter resources by their type. Specify up to five resource types in the format AWS::ServiceCode::ResourceType . For example, AWS::EC2::Instance , or AWS::S3::Bucket .

When you specify a resource-type filter for ListGroupResources , AWS Resource Groups validates your filter resource types against the types that are defined in the query associated with the group. For example, if a group contains only S3 buckets because its query specifies only that resource type, but your resource-type filter includes EC2 instances, AWS Resource Groups does not filter for EC2 instances. In this case, a ListGroupResources request returns a BadRequestException error with a message similar to the following:

The resource types specified as filters in the request are not valid.

The error includes a list of resource types that failed the validation because they are not part of the query associated with the group. This validation doesn’t occur when the group query specifies AWS::AllSupported , because a group based on such a query can contain any of the allowed resource types for the query type (tag-based or AWS CloudFormation stack-based queries).

(structure)

A filter name and value pair that is used to obtain more specific results from a list of resources.

Name -> (string)

The name of the filter. Filter names are case-sensitive.

Values -> (list)

One or more filter values. Allowed filter values vary by resource filter name, and are case-sensitive.

(string)

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

[
  {
    "Name": "resource-type",
    "Values": ["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 list all of the resources in a resource group

Example 1: The following list-resource-groups example lists all of the resources that are part of the specified resource group.

aws resource-groups list-group-resources \
    --group-name tbq-WebServer

Output:

{
    "ResourceIdentifiers": [
        {
            "ResourceArn": "arn:aws:ec2:us-west-2:123456789012:instance/i-09f77fa38c12345ab",
            "ResourceType": "AWS::EC2::Instance"
        }
    ]
}

Example 2: The following example lists all of the resources in the group that also have a ‘resource-type’ of the ‘AWS::EC2::Instance’. :

aws resource-groups list-group-resources

–group-name tbq-WebServer –filters Name=resource-type,Values=AWS::EC2::Instance

Output

Resources -> (list)

An array of resources from which you can determine each resource’s identity, type, and group membership status.

(structure)

A structure returned by the ListGroupResources operation that contains identity and group membership status information for one of the resources in the group.

Identifier -> (structure)

A structure that contains the ARN of a resource and its resource type.

ResourceArn -> (string)

The ARN of a resource.

ResourceType -> (string)

The resource type of a resource, such as AWS::EC2::Instance .

Status -> (structure)

A structure that contains the status of this resource’s membership in the group.

Note

This field is present in the response only if the group is of type AWS::EC2::HostManagement .

Name -> (string)

The current status.

ResourceIdentifiers -> (list)

Warning

** Deprecated - don’t use this parameter. Use the ``Resources`` response field instead. **

(structure)

A structure that contains the ARN of a resource and its resource type.

ResourceArn -> (string)

The ARN of a resource.

ResourceType -> (string)

The resource type of a resource, such as AWS::EC2::Instance .

NextToken -> (string)

If present, indicates that more output is available than is included in the current response. Use this value in the NextToken request parameter in a subsequent call to the operation to get the next part of the output. You should repeat this until the NextToken response element comes back as null .

QueryErrors -> (list)

A list of QueryError objects. Each error is an object that contains ErrorCode and Message structures. Possible values for ErrorCode are CLOUDFORMATION_STACK_INACTIVE and CLOUDFORMATION_STACK_NOT_EXISTING .

(structure)

A two-part error structure that can occur in ListGroupResources or SearchResources operations on CloudFormation stack-based queries. The error occurs if the CloudFormation stack on which the query is based either does not exist, or has a status that renders the stack inactive. A QueryError occurrence does not necessarily mean that AWS Resource Groups could not complete the operation, but the resulting group might have no member resources.

ErrorCode -> (string)

Possible values are CLOUDFORMATION_STACK_INACTIVE and CLOUDFORMATION_STACK_NOT_EXISTING .

Message -> (string)

A message that explains the ErrorCode value. Messages might state that the specified CloudFormation stack does not exist (or no longer exists). For CLOUDFORMATION_STACK_INACTIVE , the message typically states that the CloudFormation stack has a status that is not (or no longer) active, such as CREATE_FAILED .
