Ansible StackStorm role v2.0.0 released

By Amanda McGuinness of Ammeon Solutions

Ansible-st2 v2.0.0We’re very excited to announce that Ansible roles to deploy StackStorm have been promoted to new major version 2.0.0! 

There has been a lot of activity recently on the ansible-st2 repository, with 4 releases in the last couple of months. Ansible can now be used to deploy StackStorm on more modern operating systems and with newer third-party applications.

Mistral deprecation

The ansible-st2 release includes a breaking change: the removal of the st2mistral and postgresql roles. This is part of the StackStorm roadmap v3.3.0 changes to deprecate Mistral in favor of new workflow engine Orquesta. StackStorm 3.2.0 is the last release to support Mistral. Find out more about Orquesta at, the new StackStorm self-grown workflow engine.

Note! If you are still in the process of migrating from Mistral to Orquesta, we recommend to use older v1.7.0 release of ansible-st2 which still has mistral role in place.


In-line with the single-line installer, the StackStorm Ansible roles have been updated to:

  • Support all StackStorm OSes (Ubuntu Xenial, Ubuntu Bionic, CentOS/RHEL 7, CentOS/RHEL 8). 
  • Deprecate older OSes no longer supported by StackStorm (Ubuntu Trusty, CentOS/RHEL 6)
  • Updated to use MongoDB 4.0 on all OSes


As usual, you can download it all at Ansible Galaxy: and find source code as Github repository: We recommend pinning the role to a specific version in your infrastructure. Read more about the evolution of the ansible-st2 playbook and roles in the Releases Changelog.
