signal-workflow-execution

Description

Records a WorkflowExecutionSignaled event in the workflow execution history and creates a decision task for the workflow execution identified by the given domain, workflowId and runId. The event is recorded with the specified user defined signalName and input (if provided).

Note

If a runId isn’t specified, then the WorkflowExecutionSignaled event is recorded in the history of the current open workflow with the matching workflowId in the domain.

Note

If the specified workflow execution isn’t open, this method fails with UnknownResource .

Access Control

You can use IAM policies to control this action’s access to Amazon SWF resources as follows:

• Use a Resource element with the domain name to limit the action to only specified domains.

• Use an Action element to allow or deny permission to call this action.

• You cannot use an IAM policy to constrain this action’s parameters.

If the caller doesn’t have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute’s cause parameter is set to OPERATION_NOT_PERMITTED . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide .

Synopsis

--domain <value>
--workflow-id <value>
[--run-id <value>]

[--input <value>]
[--cli-input-json | --cli-input-yaml]

Options

--domain (string)

The name of the domain containing the workflow execution to signal.

--workflow-id (string)

The workflowId of the workflow execution to signal.

--run-id (string)

The runId of the workflow execution to signal.

--signal-name (string)

The name of the signal. This name must be meaningful to the target workflow.

--input (string)

Data to attach to the WorkflowExecutionSignaled event in the target workflow execution’s history.

--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.
