Site integral management with Puppet

After the first LHC phase where experiments and sites focused efforts to deliver the demanding wLGC metrics, now sites are facing a new dimension which is to consolidate and automate the computing services to reach a steady-state functioning. Starting form the ground, the installation and post-installation mechanics are one of the most important points for the computing centers to avoid initial installation and configuration problems. At Port d’Informació Científica the adopted solution is to steer all post-install and dynamic post-configuration using Puppet.

Puppet is a master entity were to easily define profile that get propagated around the cluster, hence fulfilling the necessities of post-install configurations, after the raw os installation, and ensuring the persistence of the profile and the defined services once has been completey installed.
