Hi all!

I’m wanting to talk to anyone who has some large-scale deployments with Ansible to chat about. Please do contact me at patg@patg.net to share or IRC “CaptTofu”

Thanks!

Regards,

Patrick

We do large scale deployments at Rackspace with Ansible. Mostly application deployment, not as much configuration management. I presented about it at the AnsibleFest in San Francisco: http://prezi.com/tyasc3-vj_id/ansible-turbo/

Does a 72-node (metal) Hadoop cluster count as ‘large-scale’? If so, check out https://github.com/analytically/hadoop-ansible!

​Here large as in lots of variations of a specific Tomcat setup (~ 100
different apps on 2-node clusters in 3 environments​ => over 600 tomcat
servers)
Especially interested on how to do inventory variables.

See also my previous post, partly on that subject:

Hi Patrick,

Currently I am using Ansible as a modelling/blueprint to large scale infrastructure. mostly interested in the system/server CM side, as well as some of middle layers side but not applications per se at least yet.

Jesse Keating, Benno Joy, among other Ansiblers were of great help to get me started. for large scale deployment there is an ansible white paper “Scaling and performance of the Ansible management tool chain”, find in the linke below my old notes in one issue i faced when running hundreds of ssh threads against several 1000s of machines, the issue was not Ansible nor the control node itself, but knowing where the issue might lie could take some time.
