start-workflow-execution

Description

Starts an execution of the workflow type in the specified domain using the provided workflowId and input data.

This action returns the newly started workflow execution.

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.

  • Constrain the following parameters by using a Condition element with the appropriate keys.

    • tagList.member.0 : The key is swf:tagList.member.0 .

    • tagList.member.1 : The key is swf:tagList.member.1 .

    • tagList.member.2 : The key is swf:tagList.member.2 .

    • tagList.member.3 : The key is swf:tagList.member.3 .

    • tagList.member.4 : The key is swf:tagList.member.4 .

    • taskList : String constraint. The key is swf:taskList.name .

    • workflowType.name : String constraint. The key is swf:workflowType.name .

    • workflowType.version : String constraint. The key is swf:workflowType.version .

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 .

Options

--domain (string)

The name of the domain in which the workflow execution is created.

--workflow-id (string)

The user defined identifier associated with the workflow execution. You can use this to associate a custom identifier with the workflow execution. You may specify the same identifier if a workflow execution is logically a restart of a previous execution. You cannot have two open workflow executions with the same workflowId at the same time within the same domain.

The specified string must not start or end with whitespace. It must not contain a : (colon), / (slash), | (vertical bar), or any control characters (\u0000-\u001f | \u007f-\u009f ). Also, it must not be the literal string arn .

--workflow-type (structure)

The type of the workflow to start.

name -> (string)

The name of the workflow type.

Note

The combination of workflow type name and version must be unique with in a domain.

version -> (string)

The version of the workflow type.

Note

The combination of workflow type name and version must be unique with in a domain.

Shorthand Syntax:

name=string,version=string

JSON Syntax:

{
  "name": "string",
  "version": "string"
}

--task-list (structure)

The task list to use for the decision tasks generated for this workflow execution. This overrides the defaultTaskList specified when registering the workflow type.

Note

A task list for this workflow execution must be specified either as a default for the workflow type or through this parameter. If neither this parameter is set nor a default task list was specified at registration time then a fault is returned.

The specified string must not start or end with whitespace. It must not contain a : (colon), / (slash), | (vertical bar), or any control characters (\u0000-\u001f | \u007f-\u009f ). Also, it must not be the literal string arn .

name -> (string)

The name of the task list.

Shorthand Syntax:

name=string

JSON Syntax:

{
  "name": "string"
}

--task-priority (string)

The task priority to use for this workflow execution. This overrides any default priority that was assigned when the workflow type was registered. If not set, then the default task priority for the workflow type is used. Valid values are integers that range from Java’s Integer.MIN_VALUE (-2147483648) to Integer.MAX_VALUE (2147483647). Higher numbers indicate higher priority.

For more information about setting task priority, see Setting Task Priority in the Amazon SWF Developer Guide .

--input (string)

The input for the workflow execution. This is a free form string which should be meaningful to the workflow you are starting. This input is made available to the new workflow execution in the WorkflowExecutionStarted history event.

--execution-start-to-close-timeout (string)

The total duration for this workflow execution. This overrides the defaultExecutionStartToCloseTimeout specified when registering the workflow type.

The duration is specified in seconds; an integer greater than or equal to 0 . Exceeding this limit causes the workflow execution to time out. Unlike some of the other timeout parameters in Amazon SWF, you cannot specify a value of “NONE” for this timeout; there is a one-year max limit on the time that a workflow execution can run.

Note

An execution start-to-close timeout must be specified either through this parameter or as a default when the workflow type is registered. If neither this parameter nor a default execution start-to-close timeout is specified, a fault is returned.

--tag-list (list)

The list of tags to associate with the workflow execution. You can specify a maximum of 5 tags. You can list workflow executions with a specific tag by calling ListOpenWorkflowExecutions or ListClosedWorkflowExecutions and specifying a TagFilter .

(string)

Syntax:

"string" "string" ...

--task-start-to-close-timeout (string)

Specifies the maximum duration of decision tasks for this workflow execution. This parameter overrides the defaultTaskStartToCloseTimout specified when registering the workflow type using RegisterWorkflowType .

The duration is specified in seconds, an integer greater than or equal to 0 . You can use NONE to specify unlimited duration.

Note

A task start-to-close timeout for this workflow execution must be specified either as a default for the workflow type or through this parameter. If neither this parameter is set nor a default task start-to-close timeout was specified at registration time then a fault is returned.

--child-policy (string)

If set, specifies the policy to use for the child workflow executions of this workflow execution if it is terminated, by calling the TerminateWorkflowExecution action explicitly or due to an expired timeout. This policy overrides the default child policy specified when registering the workflow type using RegisterWorkflowType .

The supported child policies are:

  • TERMINATE – The child executions are terminated.

  • REQUEST_CANCEL – A request to cancel is attempted for each child execution by recording a WorkflowExecutionCancelRequested event in its history. It is up to the decider to take appropriate actions when it receives an execution history with this event.

  • ABANDON – No action is taken. The child executions continue to run.

Note

A child policy for this workflow execution must be specified either as a default for the workflow type or through this parameter. If neither this parameter is set nor a default child policy was specified at registration time then a fault is returned.

Possible values:

  • TERMINATE

  • REQUEST_CANCEL

  • ABANDON

--lambda-role (string)

The IAM role to attach to this workflow execution.

Note

Executions of this workflow type need IAM roles to invoke Lambda functions. If you don’t attach an IAM role, any attempt to schedule a Lambda task fails. This results in a ScheduleLambdaFunctionFailed history event. For more information, see https://docs.aws.amazon.com/amazonswf/latest/developerguide/lambda-task.html in the Amazon SWF Developer Guide .

--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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json

  • text

  • table

  • yaml

  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on

  • off

  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64

  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Output

runId -> (string)

The runId of a workflow execution. This ID is generated by the service and can be used to uniquely identify the workflow execution within a domain.
