chef-rails-dev-box

Introduction

This project automates the setup of a development environment for Ruby on Rails core development. This is port of rails-dev-box using by Chef.

Requirements

VirtualBox
Vagrant
version required v1.1.2 later.

How To Build The Virtual Machine

Building the virtual machine is this easy:

host $ git clone [email protected]:banyan/chef-rails-dev-box.git
host $ cd chef-rails-dev-box
host $ bundle install
host $ cd chef
host $ bundle exec librarian-chef install
host $ cd ../
host $ vagrant up

That's it.

If the base box is not present that command fetches it first. The setup itself takes about 15 minutes in my MacBook Air. After the installation has finished, you can access the virtual machine with

$ vagrant ssh
Welcome to Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-29-generic x86_64)
...
vagrant@chef-rails-dev-box:~$

Caveats

For Windows User

When vagrant bootup, shared folder is mounted by using NFS. NFS is not supported on Windows hosts. (See document)

Comment this line if you are Windows user.

-  config.vm.share_folder("v-root", "/vagrant", ".", "nfs" => true)
+  # config.vm.share_folder("v-root", "/vagrant", ".", "nfs" => true)

What's In The Box

Git
Ruby 2.0.0-p0 via rbenv
Bundler
SQLite3, MySQL, and Postgres
System dependencies for nokogiri, sqlite3, mysql, mysql2, and pg
Databases and users needed to run the Active Record test suite
Node.js for the asset pipeline
Memcached

Recommended Workflow

The recommended workflow is

edit in the host computer and
test within the virtual machine.

Just clone your Rails fork in the very directory of the Rails development box in the host computer:

host $ ls
README.md   Vagrantfile puppet
host $ git clone [email protected]:rails/rails.git

Vagrant mounts that very directory as /vagrant within the virtual machine:

vagrant@chef-rails-dev-box:~$ ls
/vagrant/chef  rails  README.md  Vagrantfile

so we are ready to go to edit in the host, and test in the virtual machine.

This workflow is convenient because in the host computer one normally has his editor of choice fine-tuned, Git configured, and SSH keys in place.

Virtual Machine Management

host $ vagrant suspend # just log out
host $ vagrant resume  # resume to hack again
host $ vagrant halt    # to shutdown
host $ vagrant up      # to boot it again
host $ vagrant status  # check status
host $ vagrant destroy # DANGER: all is gone

Please check the Vagrant documentation for more information on Vagrant.
