How to set up your VPS with Chef Solo

How to set up your VPS with Chef Solo

1. What is it?

There are many different provisioning tools out there, the most popular of which are Chef and Puppet. Chef uses Ruby, Puppet uses a DSL (Domain Specific Language), there are others that use simple bash too, but today we're going to focus on Chef Solo.

2. Dependencies

To get Chef working properly on your local machine you need a few things.

Make sure you use Ruby 1.9.x and not Ruby 2.x as you will get errors with the json 1.6.1 gem on 2.x. Use rbenv or RVM to manage several different Rubies on the one machine.

Objeto é a noção de uma entidade que é definida inteiramente pelo seu comportamento. E esse comportamento é dinâmicamente selecionado. Em outras palavras, eu "peço" um objeto para "andar," e como ele vai fazer isso é inteiramente definido pelo objeto.

O exemplo:


Captura bem essa idéia. Eu tenho uma mensagem "anda," mas eu não consigo dizer o que essa função faz direto do meu código, porque isso depende no comportamento dinâmico da execução do programa (em uma linguagem estáticamente tipada você consegue optimizar isso, mas o raciocínio do código continua o mesmo).
