Learning Chef (Sandbox)

This is my chef sandbox, this repository host code of my crash course trying to understand and make Chef-Solo work with Vagrant.

The work done here is a mashup of Chef documentation, Peepcode screencast and recently rubygems-aws recipes.

I've added to the mix Berkshelf so I can manage the recipes without downloading them into my repository.

I haven't scratched the surface of Chef, heck, most likely I have no idea what I'm doing 😃

Objectives

Not only be able to understand the mixture of concepts of Chef (recipe, role, knife, data_bags, attributes, templates, ough) but also be able to get my own customized environment.

At this time I'm mixing everything into one single box (app_db) but ideally it should be able to scale and configure different apps servers from db servers.

Questions I have

• I want to run multiple applications on the same box, should I define each one as a recipe?

• Each application should have it's own database

I saw database cookbook might offer what I need, but still don't know how to use it (goes along the application? should be a data_bag or attributes?)

• Applications should be using Nginx + Puma (sockets)

I want each application uses Puma so rolling deploys can be achieved. (While I know unicorn does, I'm not a fan of it, Puma model works better to me).

Getting Started

This repository uses Bundler to manage the Ruby dependencies

gem install bundler
bundle install

Once all the gems (berkshelf, vagrant, chef) are installed, you can install the cookbooks:

berks install

All those will be installed in ~/.berkshelf

Now, you can start the app_db box with chef-solo:

vagrant up app_db

And provision it every time:

vagrant provision app_db

As mentioned before: none of the ideas here are originally mine, I bluntly stole code from everywhere (thanks Google!), so feel free to use it as you please, but don't sue me if things don't work.
