I’m looking to call groups of roles at the same time in an asynchronous fashion, but have yet to figure out how to do so. My playbook is relatively simple:

> * * *
> 
> # release.yml
> 
> - hosts: “{{ host\_group }}”
> 
> remote\_user: “{{ release\_user }}”
> 
> serial: 99
> 
> vars\_files:
> 
> - release\_vars.yml
> 
> roles:
> 
> - { role : release\_copy\_srl\_files, when : dmgr != ‘yes’ }
> 
> - { role : release\_copy\_reporting\_jars, when : reportingServer == ‘true’ }
> 
> - { role : release\_deploy\_portal\_ears, when : dmgr == ‘yes’ }
> 
> - { role : release\_deploy\_portal\_paa, when : primaryNode == ‘true’ }
> 
> - { role : release\_deploy\_portal\_paa, when : secondaryNode == ‘true’ }
> 
> - { role : release\_deploy\_appserver\_ears, when : dmgr == ‘yes’ }
> 
> - { role : release\_start\_checkout\_IHS, when : ihs\_checkout == ‘true’ }

No host will have multiple conditions met in the when statements. Being able to run these simultaneously would save about the amount of time that it’d take to have a human do the job, so the goal is to optimize this playbook to the extent that we can.

Any suggestions?

Thanks!  
Nick

Have a look at this presentation - the last part covers various ways you can run playbooks in parallel.

[http://www.slideshare.net/bcoca/more-tips-n-tricks](http://www.slideshare.net/bcoca/more-tips-n-tricks)

There’s some more discussion here [https://github.com/ansible/proposals/issues/31](https://github.com/ansible/proposals/issues/31) and mention of various other tools you could use to wrap ansible to achieve parallel runs.

Hope this helps,

Jon
