Writing and Sharing Great Modules with the Puppet Forge
The document discusses the Puppet Forge, a community platform for sharing and discovering Puppet modules, and highlights the importance of separating code from data in Puppet deployments using Hiera for data lookup. It outlines recent updates to the Forge, including a redesign, new features, and an upcoming public API, while also addressing the demand for on-premise solutions for Puppet modules. Additionally, it invites participation in Puppet Labs' community initiatives and highlights job opportunities within the organization.

- 25. Code VS Data #PuppetCamp Asyou get further along with your Puppet Deployments, separating your code (puppet resources) from the data (what package, what version) becomes increasingly important.
- 26. Imagine that you’redoing a research project in the library.
- 27. You’ve got somebooks that help accomplish your goal.
- 28. Separate Code From Data But you don’t write in those books. You keep your notes -- your data -- separate.
- 30. So where doyou express your data and how does Puppet find it?
- 31. Automatic Data Lookup Built into Puppet 3
- 32. The answer, useHiera! Seriously, these docs rock. Read them. http://docs.puppetlabs.com/hiera/1/index.html
- 33. It’s MAGIC But also, it’s not... #PuppetCamp But first, let’s take a closer look at a Puppet run.
- 36. Hello! I’m James_Bond running the RedHat license to kill downtime.
- 37. Good to know! Hmm, what does James_Bond need to enforce?.
- 38. James_Bond? Enforce External Node Forge Classifier OK, what do I need for Forge? Modules Modules Modules Modules
- 39. forge::package? Data Bindings Hiera Hiearchy Backends $clientcert $operatingsystem JSON YAML MySQL Foreman common The Puppet Master needs forge::package. To get this data... - It consults its data bindings terminus (abstraction for looking up data) - Default lookup to Hiera (key/value store for data) - Hiera consults its back-end data stores (defaults to yaml) - Hiera returns result of lookup to master (key/value or could not find)
- 40. forge::package? Data Bindings It’s screen! Hiera Hiearchy Backends $clientcert $operatingsystem JSON YAML MySQL Redis common The Puppet Master needs forge::package. To get this data... - It consults its data bindings terminus (abstraction for looking up data) - Default lookup to Hiera (key/value store for data) - Hiera consults its back-end data stores (defaults to yaml) - Hiera returns result of lookup to master (key/value or could not find)
- 41. ? $forge::package Hiearchy $clientcert $james_bond $operatingsystem $RedHat common common Hiera will examine the lookup order of its data backends and its lookup hierarchy. If you specified a variable lookup in your hierarchy, Hiera will use available facts when choosing the backend file to lookup.
- 42. Expressing the configurationof hiera data backends and lookup hierarchy 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.
- 43. Ok, so howdo I use it with my Puppet classes? #PuppetCamp Thankfully, Puppet 3 has made implementing Hiera really simple.
- 44. In the earlydays... Please don’t use the hiera() function. Consider it legacy.
- 45. In the earlydays... This is better, as the user can override this default parameter value. With this, you’re locked into hiera.
- 46. Here’s the magic! Butreally, just get yourself onto Puppet 3 and take advantage of automatic Hiera!
- 47. 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. This slide could be more visual vs text-based
- 48. Data Bindings don’t lock yourself in #PuppetCamp Additionally, protect yourself from a potential loss of Hiera.
- 49. Built into Puppet3 data_bindings were implemented to be an abstraction for data lookup, defaulting to hiera for now
- 50. There’s already analternative out there, for consulting foreman as your data backend
- 51. But really, justget yourself onto Puppet 3 and take advantage of automatic Hiera!
- 52. Hiera backends arepluggable too. Here are two examples.
- 54. Best Practices • Confirm to the Style Guide • Use Parameterized Classes • Don’t use hiera() directly #PuppetCamp Re-cap.

- 56. What have webeen up to? • Re-launch and Re-design Though we’re small, we’ve been really busy!
- 58. Lots of littlefeatures add up to a substantially nicer to use Forge.
- 59. What have webeen up to? • Re-launch and Re-design • PMT Fixes (prep for publish) • Download Counts
- 60. Download counts, nowin your search results!
- 61. What’s Next? GitHub Publish Edit your Modulefile, push your commit and we’ll do the publishing! Coming soon to a repository near you.
- 62. What’s Next? A Full & Public API Also coming soon, an actual API for doing all sorts of things with the Forge.
- 63. What’s Next? Just anexperimental mock-up of search results. Actual feature will absolutely look and behave differently.
