The State of Puppet
1 like583 views
The document outlines updates and improvements in Puppet version 3.0.0, including data/model separation, implementation of semantic versioning, and various bug fixes. It discusses the need for community engagement in shaping the roadmap and highlights plans for the next major release, 'Waldorf.' Future features aim for better performance, cleaner code, and improved user experience while acknowledging past challenges in the ecosystem.
The State of Puppet
- 2. BE TRANSPARENT • Tell you what is happening • Make decisions in public • Work together on roadmap • Work together on design • Open by default
- 3. WHAT WE HAVE DONE RECENTLY
- 4. DATA/MODEL SEPARATION • Lookup of class parameters separate from the manifest • You can assume it is there! • No manifest changes needed • Uses Hiera as the back-end
- 5. RUBY 1.9.3 ...is finally a first class citizen. This is part of 3.0.0 Fully supported. All bugs fixed. (Probably)
- 6. PUPPET MODULE TOOL • Project Geordi La Forge • PMT ships with 3.0.0 • Making it more awesome! • Buffing up publishing • Enhance the forge
- 7. VARIABLE SCOPE FIXED • No more dynamic scope • Killed deprecation warnings! • Local, then inherited... • ...then node, then global.
- 8. GIVE BACK MEMORY • Daemon mode used to grow and grow... • Now, we return memory to the OS • Part of our performance improvement strategy
- 9. ENC VS ENVIRONMENTS • You could set the client environment from the ENC • The client would ignore you (sometimes) • Now it doesn’t • Bug fix, not feature • Still great!
- 10. PLUGIN SYNC • This worked unevenly • Failures on first run • Oddities about what can by synced and used successfully • Now, uniform and standard
- 11. DSL POLISH • Add “unless” to the language • Allow keywords as resource parameters and properties • Fixed some parser bugs (like ‘-’ in variable names) • More of this coming...
- 12. HIDDEN CHANGES • Lots of bugs fixed • Code cleanup • Performance improvements • Correctness fixes • None of them visible
- 13. FINALLY SHIPPING! • Puppet 3.0.0 • Facter 2.0.0 • Hiera 1.0.0
- 14. COMMITTING TO SEMVER • Semantic Versioning FTW • We are moving all our projects over • SemVer 2.0.0-rc.1 compliant
- 17. MINOR VERSION Compatible new features
- 18. PATCH VERSION Bug fix with no other behavioural or functional changes
- 19. WHICH MEANS? • You have version numbers that match the way we write and ship code • You can be confident about the scope of changes in any release
- 21. OS PACKAGES FOR RELEASE CANDIDATES
- 22. MONTH DEVELOPMENT RELEASES • Waldorf is the next major release after Telly (3.0.0) • We will ship a tested version every month as a preview • This way you don’t have changes a year old before they ship to the community • Plus OS packages!
- 23. NOT DONE YET...
- 24. OLD MISTAKES STILL HAUNT US • Parameterized classes don’t work everywhere • undef vs nil • classes with ‘-’ in the name
- 25. SLOW MOVING ECOSYSTEM • Dashboard has not gotten a lot of love recently • Puppet Labs modules need more attention • ...but we are starting to invest in them.
- 26. BROKEN (OR DELAYED) PROMISES • import isn’t deprecated • The static compiler isn’t the default • Facter doesn’t have typed or structured facts
- 27. THE FUTURE
- 28. THE ECOSYSTEM • Shipping structured and typed facts without the ecosystem is a no-go • On release, new features should work everywhere
- 29. THE NEXT CHALLENGE Waldorf, kicking ass and taking names
- 30. EXPERIMENT ONE We are going to fix some high-voted tickets
- 31. VOTES SHAPE THE ROADMAP • We said votes matter before • It wasn’t really true • I don’t expect you to believe us this time... • ...so we are gonna fix tickets, then ask you to believe us
- 32. VOTES SHAPE THE ROADMAP • We want community input into the roadmap • This seems a solid choice • Success is that votes get used by the community • ...and that we use them to shape the roadmap!
- 34. REDMINE “ACCEPTED” TICKETS This is the scrum “unsorted product backlog”
- 35. REDMINE “3.X” TARGET VERSION This is “we might fix it before 4.0.0”
- 36. GONNA FIX THAT UP • Target open tickets at the next numeric version • Means “trying to fix for that release” • Still shipping time-based product, so things will miss
- 37. OTHER EXPERIMENTS You bring ‘em, We try ‘em
- 38. TECH FOR WALDORF This is all speculative, no promises.
- 39. STATIC COMPILER • Missed Telly, but only just • Content reference, not URI • Single file catalog? • Easier push model?
- 40. STRUCTURED FACTS • Really, structured and typed • JSON is the template for supported types and structures • Full ecosystem support • Third party facts only, initially
- 41. BETTER GRAPH PROCESSING • Improve graph handling in the Puppet Agent • Fix the “anchor” pattern • Improves performance and logic • Allows future improvements to the catalog and graph
- 42. BETTER ENVIRONMENTS • Different versions of a type in different environments • Turns out that is pretty hard (thanks, Ruby) • We will make it easy • Fix performance cost too
- 43. CLEANER, DOCUMENTED CODE • Easier to use Puppet as a library or extend it • Better API definitions • Richer integrations
- 44. THANK YOU ALL
