[ aws . greengrassv2 ]



Retrieves a paginated list of component summaries. This list includes components that you have permission to view.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

list-components 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: components


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


--scope (string)

The scope of the components to list.

Default: PRIVATE

Possible values:



--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.

See ‘aws help’ for descriptions of global parameters.


To list components

The following list-components example lists each component and its latest version defined in your AWS account in the current Region.

components -> (list)

A list that summarizes each component.


Contains information about a component.

arn -> (string)

The ARN of the component version.

componentName -> (string)

The name of the component.

latestVersion -> (structure)

The latest version of the component and its details.

arn -> (string)

The ARN of the component version.

componentVersion -> (string)

The version of the component.

creationTimestamp -> (timestamp)

The time at which the component was created, expressed in ISO 8601 format.

description -> (string)

The description of the component version.

publisher -> (string)

The publisher of the component version.

platforms -> (list)

The platforms that the component version supports.


Contains information about a platform that a component supports.

name -> (string)

The friendly name of the platform. This name helps you identify the platform.

If you omit this parameter, IoT Greengrass creates a friendly name from the os and architecture of the platform.

attributes -> (map)

A dictionary of attributes for the platform. The IoT Greengrass Core software defines the os and platform by default. You can specify additional platform attributes for a core device when you deploy the Greengrass nucleus component. For more information, see the Greengrass nucleus component in the IoT Greengrass V2 Developer Guide .

key -> (string)

value -> (string)

nextToken -> (string)

The token for the next set of results, or null if there are no additional results.
