Mistral Client Commands Guide

The Mistral CLI can be used with mistral command or via OpenStackClient.

Mistral Client

The best way to learn about all the commands and arguements that are expected is to use the mistral help comand.

$ mistral help
usage: mistral [--version] [-v] [--log-file LOG_FILE] [-q] [-h] [--debug]
               [--os-mistral-url MISTRAL_URL]
               [--os-mistral-version MISTRAL_VERSION]
               [--os-mistral-service-type SERVICE_TYPE]
...

It can also be used with the name of a sub-command.

$ mistral help execution-create
usage: mistral execution-create [-h] [-f {json,shell,table,value,yaml}]
                                [-c COLUMN] [--max-width <integer>]
                                [--print-empty] [--noindent] [--prefix PREFIX]
                                [-d DESCRIPTION]
                                workflow_identifier [workflow_input] [params]

Create new execution.

positional arguments:
  workflow_identifier   Workflow ID or name. Workflow name will be deprecated
                        sinceMitaka.
...

OpenStack Client

OpenStack client works in a similar way, the command openstack help shows all the available commands and then openstack help <sub-command> will show the detailed usage.

The full list of Mistral commands that are registered with OpenStack client can be listed with openstack command list. By default it will list all commands grouped togehter, but we can specify only the Mistral command group.

$ openstack command list --group openstack.workflow_engine.v2
+------------------------------+-----------------------------------+
| Command Group                | Commands                          |
+------------------------------+-----------------------------------+
| openstack.workflow_engine.v2 | action definition create          |
|                              | action definition definition show |
|                              | action definition delete          |
|                              | action definition list            |
|                              | action definition show            |
|                              | action definition update          |
|                              | action execution delete           |
...

Then detailed help output can be requested for an individual command.

$ openstack help workflow execution create
usage: openstack workflow execution create [-h]
                                           [-f {json,shell,table,value,yaml}]
                                           [-c COLUMN] [--max-width <integer>]
                                           [--print-empty] [--noindent]
                                           [--prefix PREFIX] [-d DESCRIPTION]
                                           workflow_identifier
