get-flow-template

Description

Gets the latest version of the DefinitionDocument and FlowTemplateSummary for the specified workflow.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  get-flow-template
--id <value>
[--revision-number <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--id (string)

The ID of the workflow.

The ID should be in the following format.

urn:tdm:REGION/ACCOUNT ID/default:workflow:WORKFLOWNAME

--revision-number (long)

The number of the workflow revision to retrieve.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. 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 get a flow definition

The following get-flow-template example gets a definition for a flow (workflow).

aws iotthingsgraph get-flow-template \
    --id "urn:tdm:us-west-2/123456789012/default:Workflow:MyFlow"

Output:
