Beginner's Thoughts on Making Puppet Modules - David Klann - PuppetCamp Chicago '12

  2. 2. On the Journey to Config Automation● Why config management? – small operation – scripts and version control (mostly) just fine – what are the issues were trying to solve?
  3. 3. Why Puppet● Standardization● Community Support● Puppet Labs Apparent Commitment to Free Software and the Open Source model● Architecture
  4. 4. Bumps in the Road● Community Puppet – Puppet DSL: alien language (Rails déjà vu) – frequent Puppet releases caused breakage – packaging
  5. 5. Fixing Potholes● Puppet Enterprise – packaging: solved – update breakage: solved – DSL: not solved, but getting used to it
  6. 6. Intro to Puppet Modules● Whats to Like – consistent view – consistent interface – separation of data and logic
  7. 7. Intro to Puppet Modules● Whats to Despise – bugs – useless error messages – pe_accounts: huh?
  8. 8. Puppet Mastery● Goal: a series of modules to manage ISP services (NTP, SNMP, postfix, dovecot, RADIUS, etc.) – stand-alone modules? – how to integrate? e.g., /etc/sysconfig/iptables: stand-alone? as part of another module?
