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 arguments that are expected
is to use the mistral help command.
$ 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
since Mitaka.
...
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 together, 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]
