Ryan, a former Red Hat sysadmin, now serves as the product owner for the Puppet Forge, a community-driven platform for sharing Puppet modules. The document discusses best practices for Puppet deployments, including the importance of separating code from data using Hiera, and highlights recent improvements and features of the Puppet Forge. Future additions like a public API and opportunities for community involvement in product development are also mentioned.

- 23. Code VS Data Tuesday, February 26, 13 As you get further along with your Puppet Deployments, separating your code (puppet resources) from the data (what package, what version) becomes increasingly important.
- 24. Tuesday, February 26, 13
- 25. Tuesday, February 26, 13 How do you get from A to B?
- 26. Tuesday, February 26, 13 The answer, use Hiera! Seriously, these docs rock. Read them. http://docs.puppetlabs.com/hiera/1/index.html
- 27. It’s MAGIC But also, it’s not... Tuesday, February 26, 13 But first, let’s take a closer look at a Puppet run.

- 31. I need the value for $forge::package_name. How should I conduct my search? Tuesday, February 26, 13
- 32. I need the value for $forge::package_name. How should I conduct my search? Tuesday, February 26, 13 Hiera lets you express data in some structured format (which is pluggable). You then establish a hierarchy of lookup, however you like, usually based on facts.
- 33. I need the value for $forge::package_name. How should I conduct my search? $clientcert $operatingsystem common Tuesday, February 26, 13 Consider your hierarchy the lookup order.
- 34. ? $forge::package_name $clientcert $operatingsystem common Tuesday, February 26, 13
- 35. ? $forge::package_name $james_bond $RedHat common Tuesday, February 26, 13 Facts can be used for a dynamic hierarchy.
- 36. ? $forge::package_name $james_bond $RedHat common Tuesday, February 26, 13 Hiera will simply consult the structured data, looking for variable names, expecting files named after your entry in hiera.yaml
- 37. ? $forge::package_name $james_bond $RedHat common Tuesday, February 26, 13 Hierarchy matters. The package name is now tmux.
- 38. Ok, so how do I implement it? Tuesday, February 26, 13 Thankfully, Puppet 3 has made implementing Hiera really simple.
- 39. Tuesday, February 26, 13 Please don’t use the hiera() function. Consider it legacy.
- 40. Tuesday, February 26, 13 This is better, as the user can override this default parameter value. With this, you’re locked into hiera.
- 41. Tuesday, February 26, 13 But really, just get yourself onto Puppet 3 and take advantage of automatic Hiera!
- 42. Data Bindings don’t lock yourself in Tuesday, February 26, 13 Additionally, protect yourself from a potential loss of Hiera.
- 43. Data Lookup Order • Use explicit class declaration values • Query Data Binding • Use the default value from class. • Fail compilation with an error if no value can be found. Tuesday, February 26, 13
- 44. Built into Puppet 3 Tuesday, February 26, 13

- 46. Tuesday, February 26, 13 But really, just get yourself onto Puppet 3 and take advantage of automatic Hiera!
- 47. Best Practices • Confirm to the Style Guide • Use Parameterized Classes • Don’t use hiera() directly Tuesday, February 26, 13 Re-cap.
