Dmitri,
I think I got it.
"st2/st2common/st2common/util/workflow/mistral.py"
StackStorm uses function "_transform_action" here to transform action from
StackStorm action style to "st2.action" style, and then call Mistral to execute
workflow, since "st2.action" is Mistral's custom action.
Please help to double confirm.
Thanks,
Tony

Dmitri,

Could you please help to explain how it is implemented?
examples.mistral-basic:
description: A basic workflow that runs an arbitrary linux command.
type: direct
input:
- cmd
output:
stdout: <% $.stdout %>
tasks:
task1:
action: core.local cmd=<% $.cmd %> <<<< Here calls StackStorm
custom action.
publish:
stdout: <% $.task1.stdout %>
stderr: <% $.task1.stderr %>
Thanks,
Tony

Tony,
You can also connect Mistral with Ansible via StackStorm and Ansible
integration pack:
1) StackStorm http://docs.stackstorm.com
2) https://github.com/StackStorm/st2contrib/tree/master/packs/ansible
StackStorm is open-source Apache 2.0 "wrapper" around Mistral workflow service
that integrates 3rd party tools.
Disclosure: I work for StackStorm, I think it's appropriate to pitch here an
open source project that addresses the problem.
DZ.

Dear Mistral developers and testers,
We have developed some Ansible playbooks for operation automation, and we are
investigating if we can change the automation engine from Ansible to Mistral
since Mistral has powerful workflow control.
Could you please help to provide how to let Mistral call Ansible playbook or
Ansible module?
My understanding is to use ssh std_action to let Mistral access Ansible server
to call Ansible playbook/modules since Mistral ad-hoc action must base on an
existing system action.
Another question is:
If we install Mistral and Ansible on a same server, is it possible to simplify
it?
Thanks in advance,
Tony
