Future Approaches to Working with Modules
Henrik Lindberg

The Vision

Starting out

Making Your Puppets

First attempt at running

Testing
Syntax Error : got ‘:’ expected ‘}’
on line 1

Avoiding Complexity is Natural

Simplicity through Denial

Best Practices
Use modules from the beginning
Use version control
Use sound design principles
think in terms of reuse
separation of concerns
organize in terms of specificity:
puppet, common, generic, application, site, instance…

A New Set of Issues
What files goes where, and why
Manage dependencies
Collaboration within and between organizations

Isn’t there an app for that?

Geppetto Project
What is Geppetto?
Why did we create it?
What does it do?
How can I get it?
How can I contribute?

Geppetto Objectives
Flatten the learning curve
Support Puppet best practices
Encourage sharing

What is in Geppetto
Puppet Manifest editor
Module meta data editor
Incremental builders
validates puppet manifests
validates cross references (functions, types, definitions)
validates modulefiles
keeps metadata in sync (files and checksums)
Project wizards
Streamlined module publication/consumption to/from the Puppet Forge.

Puppet Manifest Editor
Syntax coloring
set your own preferences
Integrated fast validation / error markers
Quick fixes
Templates
add your own
Code completion

Incremental Builders
Validates Puppet Manifests
Validates cross references
functions, types, definitions, classes, parameters
understands visibility as defined by dependencies
Validates modulefiles
Keeps metadata in sync
files and checksums in metadata.json

Project Wizards
New Puppet Module
Get Module from Forge
Empty (blank) Puppet project
Export Module for upload to Forge

Packaging
All in one download, ready to use
integrated with svn and git
As Eclipse plugins
Command line interface (enhanced puppet module tool).
Open source (Apache, EPL)

How to contribute

Collaboration / Roadmap for the Forge
Collaboration
within and between organizations using the same mechanisms.
Support full set of use cases
get/update, install/use, repair/modify, share/contribute
Support additional composition patterns
Group/lineup
Fragments
Private vs. Exported (everything is API)
Improved dependency management
install a module, also get its dependencies
only gives you latest version (problem: stability)
no version ranges
Use of git
