1. DEPLOY EVERYTHING WITH CAPISTRANO without the sweat and tears of frustration
2. Capistrano was originally designed to simplify and automate deployment of web applications to distributed environments, and was originally created to work with Ruby on Rails applications.
3. HOW IT WORKS $ bundle exec cap staging deploy SSH Remote push Update from Github
4. HOW TO USE IT Capfile The default Capfile generated by capify is pretty minimal config/deploy.rb This is the file that contains your Rails application’s deployment configuration config/deploy/environment_name.rb This file have specific configurations for the specific environment
5. Directory Structure [deploy_to] [deploy_to]/releases [deploy_to]/releases/20080819001122 [deploy_to]/releases/... [deploy_to]/shared [deploy_to]/shared/log [deploy_to]/shared/pids [deploy_to]/shared/system [deploy_to]/current -> [deploy_to]/releases/20100819001122 Where [deploy_to] is where you want Capistrano to be deploying to on your server
6. config/deploy.rb set :protected_stages, %w(production) # Capistrano will ask to confirm deployment to those stages require 'capistrano/ext/multistage' require "bundler/capistrano" require 'capistrano_colors' set :application, "app_name" set :repository, "git@github.com:davidslv/app_name.git" set :scm, "git" set :ssh_options, { :forward_agent => true } set :use_sudo, false set :deploy_via, :remote_cache # Saves time, as it doesn't git clone the repository every time! desc 'restart' deploy.task :restart, :roles => :web do run "touch #{current_path}/tmp/restart.txt" end ...
7. config/deploy/production.rb server 'hubberdb.domain.com', :app, :cron, :cdn, :backup, :db, :primary => true server 'hubberweb.example.com', :app, :web, :sync_cdn server 'powerserver1.example.com', :app, :queue, :sync_cdn server 'powerserver2.example.com', :app, :scheduler, :sync_cdn set :user, "squid" set :env, 'production' set :rails_env, 'production' set :branch, "production" set :keep_releases, 10 set :deploy_to, "/var/www/#{application}" after "deploy:restart", "deploy:cleanup" after 'deploy:symlink' do run "ln -s #{shared_path}/lib/file_name.rb #{release_path}/config/environments/" end before "maintenance:enable", "newrelic:disable_monitoring" after "maintenance:disable", "newrelic:enable_monitoring"
8. "We can't have continuous deployment without automating deployment!" -- Rob Harr
