Puppet
From Wikitech
puppet is the main configuration management tool to be used on the Wikimedia clusters.

Puppetmaster
The puppetmaster server in pmtpa is sockpuppet.pmtpa.wmnet.
Installation
Simply use the (backported) puppetmaster Ubuntu package:
# apt-get install puppetmaster
Configuration
The default configuration is very usable, but we've made some tweaks here and there.
MD5 is broken, use SHA1 for signing certificates:
ca_md=sha1
Todo
- More secure certificate signing
- Better, more automated version control
- Better tools for adding/maintaining node definitions
