Gets a system.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.


--id <value>
[--revision-number <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]


--id (string)

The ID of the system to get. This ID must be in the user’s namespace.

The ID should be in the following format.

urn:tdm:REGION/ACCOUNT ID/default:system:SYSTEMNAME

--revision-number (long)

The number that specifies the revision of the system to get.

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.


To get a system

The following get-system-template example gets a definition for a system.

aws iotthingsgraph get-system-template \
    --id "urn:tdm:us-west-2/123456789012/default:System:MySystem"


    "description": {
        "summary": {

            "arn": "arn:aws:iotthingsgraph:us-west-2:123456789012:System/default/MyFlow",
            "revisionNumber": 1,
            "createdAt": 1559247540.656
        "definition": {

            "text": "{\ntype MySystem @systemType(id: \"urn:tdm:us-west-2/123456789012/default:System:MySystem\", description: \"\") {\n  camera: Camera @thing(id: \"urn:tdm:aws/examples:deviceModel:Camera\")\n  screen: Screen @thing(id: \"urn:tdm:aws/examples:deviceModel:Screen\")\n  motionSensor: MotionSensor @thing(id: \"urn:tdm:aws/examples:deviceModel:MotionSensor\")\n  MyFlow: MyFlow @workflow(id: \"urn:tdm:us-west-2/123456789012/default:Workflow:MyFlow\")\n}\n}"
