get-device-definition-version¶

Description¶

Retrieves information about a device definition version.

Synopsis¶

  get-device-definition-version
--device-definition-id <value>
--device-definition-version-id <value>
[--next-token <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--device-definition-id (string) The ID of the device definition.

--device-definition-version-id (string) The ID of the device definition version. This value maps to the ‘’Version’’ property of the corresponding ‘’VersionInformation’’ object, which is returned by ‘’ListDeviceDefinitionVersions’’ requests. If the version is the last one that was associated with a device definition, the value also maps to the ‘’LatestVersion’’ property of the corresponding ‘’DefinitionInformation’’ object.

--next-token (string) The token for the next set of results, or ‘’null’’ if there are no additional results.

--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.

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 get a device definition version

The following get-device-definition-version example retrieves information about the specified version of the specified device definition. To retrieve the IDs of all versions of the device definition, use the list-device-definition-versions command. To retrieve the ID of the last version added to the device definition, use the get-device-definition command and check the LatestVersion property.

aws greengrass get-device-definition-version \
    --device-definition-id "f9ba083d-5ad4-4534-9f86-026a45df1ccd" \
    --device-definition-version-id "83c13984-6fed-447e-84d5-5b8aa45d5f71"

Output¶

Arn -> (string)

The ARN of the device definition version.

CreationTimestamp -> (string)

The time, in milliseconds since the epoch, when the device definition version was created.

Definition -> (structure)

Information about the device definition version.

Devices -> (list)

A list of devices in the definition version.

(structure)

Information about a device.

CertificateArn -> (string)

The ARN of the certificate associated with the device.

If true, the device’s local shadow will be automatically synced with the cloud.

ThingArn -> (string)

The thing ARN of the device.

Id -> (string)

The ID of the device definition version.

NextToken -> (string)

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

Version -> (string)

The version of the device definition version.
