What I’m Going to Talk About

3. Hieradata
the single source of truth

4. with Hiera it’s easy to
specify parameter values specific to
a location, role, profile, fqdn, or
whatever facts you decide

5. no defaults in modules
to be the single source of truth for all modules
allows Hieradata

6. Roles
defined exclusively in Hiera

7. roles provide the layer
of abstraction between
business logic and
operations logic

8. Profiles
modules that abstract modules

9. profiles provide the
layer of
abstraction between
operations logic and
module logic

10. Testing
using rspec-puppet and beaker

11. Test Driven Development
● Provides rapid feedback
● Produces high quality,
robust code

12. Unit tests are provided using the
rspec-puppet Gem.
They help to ensure that your
module passes the compilation
phase.

13. • Acceptance tests are provided
using the Beaker Gem.
• They help to ensure that your
module does what you expect
on a live node.
• The Serverspec Gem allows
you to compare the end state of
that live node to a set of RSpec
• Expectations.
