lightchef

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
