No Easy Answers

16. Module TIME?
When are we going to do some real work?

17. Configuration AS CODE
DOWN TO the MODULES you USE

18. /etc/puppetlabs/puppet
├── modules
│ ├── concat
│ ├── dhcp
│ ├── epel
│ ├── hiera
│ ├── hiera-puppet
│ ├── limits
│ ├── mongodb
│ ├── mysql
│ ├── nodejs

19. Puppet Forge
Clearing House for modules you should be using

20. Github
Not everything is on the forge... yet.

21. Forking
Fork to Eat not to LIVE - aka Stop the fork

22. Roll your own
Don’t reinvent the wheel

23. Learning more
Don’t Forget irc #puppet - #puppet-dev - Mailing lists

24. class boundary {
require boundary::params
require boundary::dependencies
$id = $boundary::params::id
$apikey = $boundary::params::apikey
$collector = $boundary::params::collector
$collector_port = $boundary::params::collector_port
file { '/etc/bprobe/':
ensure => directory,
mode => '0755',
owner => 'root',
group => 'root',
}
package { 'bprobe':
ensure => latest,
require => File['/etc/bprobe'],
}

25. Puppet has more then a DSL
Sometimes you just need to write a little ruby

26. class evil {
define loop () {
notice("${name}")
}
loop { ['this', 'is', 'evil']:}
}
class{"evil":}
$ puppet apply evil.pp
notice: Scope(Evil::Loop[this]): this
notice: Scope(Evil::Loop[is]): is
notice: Scope(Evil::Loop[evil]): evil

27. node_config.vm.provision :puppet do |puppet|
puppet.manifests_path = 'provision/manifests'
puppet.module_path = 'provision/modules'
end
Vagrant
Learn to ♥ it
