? Why I separated into serverspec and specinfra

Slide 29

Slide 29 text

I’ve created a very simple conﬁguration management tool as a proof of concept

You can create Another type of serverspec with SpecInfra easily

Slide 34

Slide 34 text

But higher abstraction brings more complexity …

Slide 35

Slide 35 text

Why I started this project ?

Slide 36

Slide 36 text

I’m heavy Puppet user since 2007

Slide 37

Slide 37 text

My old puppet manifests are not fully modularized

Slide 38

Slide 38 text

I’ve decided to refactor my puppet manifests

Slide 39

Slide 39 text

Refactoring needs test code

Slide 40

Slide 40 text

But there are no testing tools meet my needs

Slide 41

Slide 41 text

So I made my own testing tool

Slide 42

Philosophy "

Slide 43

Slide 43 text

Simpleness

Slide 44

Slide 44 text

Easy to use

Slide 45

Slide 45 text

Support Ruby 1.8.7 (Because for supporting RHEL/CentOS)

Slide 46

Slide 46 text

No need other than Ruby

Slide 47

Slide 47 text

Even Ruby is not needed with SSH

Slide 48

Slide 48 text

Independent from any conﬁguration management tools

Slide 49

Slide 49 text

I love the UNIX philosophy, KISS principle
