A Capistrano Rails Guide

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

	load 'deploy/assets'

	namespace :deploy do
	namespace :assets do
	desc 'Run the precompile task locally and rsync with shared'
	task :precompile, :roles => :web, :except => { :no_release => true } do
	%x{bundle exec rake assets:precompile}
	%x{rsync --recursive --times --rsh=ssh --compress --human-readable --progress public/assets #{user}@#{host}:#{shared_path}}
	%x{bundle exec rake assets:clean}
	end

	#!/bin/sh
	# Just copy and paste the lines below (all at once, it won't work line by line!)
	# MAKE SURE YOU ARE HAPPY WITH WHAT IT DOES FIRST! THERE IS NO WARRANTY!

	function abort {
	echo "$1"
	exit 1
	}

	set -e

	if exists("b:did_indent")
	finish
	endif
	let b:did_indent = 1

	require 'rubygems'
	require 'eventmachine'
	require 'em-http' # gem install em-http-request
	require 'yajl' # gem install yajl-ruby

	class String
	def bold
	"\033[1m#{self}\033[0m"
	end
	end

	for (var i = 0; i < 1024 * 1024; i++) {
	process.nextTick(function () { Math.sqrt(i) } )
	}
