rvm1cap3

This is simple ruby app with one model and his migration. The purpose of the repo is to guide you through process of integration capistrano3 and setup multi staging deploy on server with rvm. There are two deployment servers production (use ruby env) and staging (use rvm)

passwordless login

This setup requires passwordless login from your dev machine to the remote machine and also that the server have passwordless read access to your git repo

One way to accomplish that is with private key and ssh key forwarding. More info:

required gems

capistrano3 is used for actual deployment

capistrano-rails is used for rails specific task like run rake db:migrate and rake assets:precompile

rvm1-capistrano3 is used for detection of ruby binary on the remote machine (where we want to deploy)

Add these to your Gemfile and install them

gem 'capistrano', '~> 3.2.0'
gem 'capistrano-rails', '~> 1.1'
gem 'rvm1-capistrano3', require: false

settings

capistrano

init capistrano

bundle exec cap install

init stages in our case production and staging

bundle exec cap install STAGES=staging,production

capistrano-rails

add this to your Capefile

require 'capistrano/rails'

rvm1-capistrano3

rvm1-capistrano3 are required to deploy only to the rvm server, add this to your Capefile

# Use rmv only for stageing 
task :use_rvm do
  require 'rvm1/capistrano3'
end

task 'staging' => [:use_rvm]

deploy configs

in config/deploy.rb specify application name and path to the git repository

set :application, 'rvm1cap3'
set :repo_url, 'git@github.com:vkdimitrov/rvm1cap3.git'

in config/deploy/<stagin.rb, production.rb>

You have to specify ruby version you want to use

set :rvm1_ruby_version, "2.1.1"

Tell the capistrano where to deploy

set :deploy_to, '/home/evomedia/rvm1cap3'

Fill your remote machine user and ip
