create-flow-template

Description

Creates a workflow template. Workflows can be created only in the user’s namespace. (The public namespace contains only entities.) The workflow can contain only entities in the specified namespace. The workflow is validated against the entities in the latest version of the user’s namespace unless another namespace version is specified in the request.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  create-flow-template
--definition <value>
[--compatible-namespace-version <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--definition (structure)

The workflow DefinitionDocument .

language -> (string)

The language used to define the entity. GRAPHQL is the only valid value.

text -> (string)

The GraphQL text that defines the entity.

Shorthand Syntax:

language=string,text=string

JSON Syntax:

{
  "language": "GRAPHQL",
  "text": "string"
}

--compatible-namespace-version (long)

The namespace version in which the workflow is to be created.

If no value is specified, the latest version is used by default.

--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.

See ‘aws help’ for descriptions of global parameters.

Examples

To create a flow

The following create-flow-template example creates a flow (workflow). The value of MyFlowDefinition is the GraphQL that models the flow.

aws iotthingsgraph create-flow-template \
    --definition language=GRAPHQL,text="MyFlowDefinition"

Output:

{
    "summary": {
        "createdAt": 1559248067.545,
        "id": "urn:tdm:us-west-2/123456789012/default:Workflow:MyFlow",
        "revisionNumber": 1
    }
}

For more information, see Working with Flows in the AWS IoT Things Graph User Guide.

Output

summary -> (structure)

The summary object that describes the created workflow.

id -> (string)

The ID of the workflow.

arn -> (string)

The ARN of the workflow.

revisionNumber -> (long)

The revision number of the workflow.

createdAt -> (timestamp)

The date when the workflow was created.
