Puppet Training Notes from Day 3.

Jesse Morgan

Final notes from day 3:

  1. Using an External Node Classifier(ENC) is considered best practice over site.pp
  2. There is a “puppet visual index” that has useful examples
  3. You can use ~> and -> to chain dependencies to help make things more readable.
  4. If I can figure out how to integrate it, I could use LDAP inventory tags to indicate puppet classes
  5. Hiera can be used to extract out data from configs
  6. Once data is abstracted out, I can put them on github and puppetforge
  7. the config_version parameter can be used to control the format of the puppet version (using date command, for example)
  8. There is a style guide available for puppet- it’s what puppet-lint uses.
  9. there is a vim-puppet plugin on github, however it’s currently broken in apt on ubuntu
  10. syntastic may be worth checking into to make vim a better IDE
  11. I really need to reconfigure ctags for perl.
  12. I should use case default: { fail(“this ${module_name} isn’t supported here”)} for better errors on case statements
  13. ask.puppetlabs.comn is a great resource when IRC fails me.
  14. I can use rspec with puppet to do TDD. This sounds very promising.
  15. Certification is $200, however I get get a 25% discount. I should be able to pass this.
  16. If puppet dashboard is slow, clean out old reports.
  17. Consider signing up for the test pilot program.
