very very very basic guide for deploy rails application to local application

capistrano deploy to local vagrant

# assumptions: virtualbox, vagrant already installed
# and there is a box lucid32

1. rails new appdmeo , gem capistrano , then bundle
2. vagrant init lucid32
3. capify .

# !important 
# vagrant ssh-config >> ~/.ssh/config
# vagrant ssh-config | grep IdentityFile | awk '{print $2}' that's where private key located
# then change the file's(~/.ssh/config) first line "host localhost" to "host vagrant"
# then modify deploy.rb:

set :application, "capdemo"
set :scm, :none
set :repository,  "."
set :local_repository, "."

server 'vagrant', :web, :app, :db
set :user, "vagrant"
set :use_sudo, false

set :deploy_to, "/home/#{user}/apps"
set :deploy_via, :copy
set :copy_exclude, "log/*"

4. cap deploy:setup

5. ssh to your vagrant box , you'll find the deployed app location in /home/vagrant/apps
   ssh vagrant or vagrant ssh , both are ok now , because in ~/.ssh/confg there is a config file we copyed from vagrant ssh-config
