>From StackStorm's document, it can run Mistral's workflow, and Mistral workflow can call StackStorm custom actions.
Could you please help to explain how it is implemented?

            action: core.local cmd=<% $.cmd %>     <<<< Here calls StackStorm custom action.
                stdout: <% $.task1.stdout %>
                stderr: <% $.task1.stderr %>

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.

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,
