A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

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".

// REQUIRED VARS. Defaults to a 950px wide, 24-column grid that has 30px wide units and 10px wide
// gutters. If you do the fluid grid, then this 950/24/30/10px size will become the maximum size.
$grid_type: fixed !default
$grid_columns: 24 !default
$grid_column_width: 30 !default
$grid_gutter_width: 10 !default

// GENERATED VARS. You can ignore these.
$grid_full_width: $grid_columns * $grid_column_width + $grid_columns * $grid_gutter_width - $grid_gutter_width
$grid_column_width_percent: ($grid_column_width / $grid_full_width * 100) * 1%

# Who needs HAML when you have YAML + ERB? :)

# See example.yaml below for an example. You can run this code
# by cloning this gist and then `ruby _yerb.rb example.yaml`.

# Notice that you need Ruby 1.9 so the hash order is preserved.
# Obviously, this is just for fun. Definitely slow as hell.

# 1) Point *.example.com in your DNS setup to your server.

# 2) Setup an Apache vhost to catch the star pointer:

# 3) Set the current account from the subdomain
