Three cool things about puppet


• Resource abstraction layer : you don’t need to know how to install a package


user { 'dave': ensure => present, uid => '507', gid => 'admin', shell => '/bin/zsh', home => '/home/dave', managehome => true, }


• Meta-data: cloud-init

#cloud-‐configapt_update: trueapt_upgrade: true

packages:-‐ ruby1.8-‐ puppet

puppet: conf: agent: server: "puppet.software-‐improvers.com" # certname %i: instance-‐id; %f: fqdn certname: "%i.%f"

Ok a fourth: environments


env/ production/ modules/ manifests/ dev/ modules/ manifests/ unassigned/ modules/ manifests/

-Code your environment- Re use code = reuse environment

Multi-OS!
