Lightchef

Configuration management tool like Chef which is simpler and lighter than Chef

Concept

Lighter than Chef
It's just like Chef. No compatibility.
No idempotence
DSL like Chef
Without compilation
- All code in recipes will be executed when they are evaluated.
- To write recipes easier
Use Ohai
No role, environment and cookbook

Examples of Recipes

resource "name" do
  action :action
  property "value"
end

Usage

$ sudo lightchef execute -j example/node.json example/recipe.rb
