Vagrant Setup

This tutorial guides you through creating your first Vagrant project.

We start with a generic Ubuntu VM, and use the Chef provisioning tool to:

Afterwards, we'll see how easy it is to package our newly provisioned VM

	namespace :db do desc "Backup project database. Options: DIR=backups RAILS_ENV=production MAX=7"
	task :backup => [:environment] do
	datestamp = Time.now.strftime("%Y-%m-%d_%H-%M-%S")

	base_path = File.join(base_path, ENV["DIR"] \|\| "backups")
	backup_base = File.join(base_path, 'db_backups')
	backup_folder = File.join(backup_base, datestamp)
	backup_file = File.join(backup_folder, "#{RAILS_ENV}_dump.sql")
	FileUtils.mkdir_p(backup_folder)
	db_config = ActiveRecord::Base.configurations[RAILS_ENV]
