Mina::Multistage

Plugin for Mina that adds support for multiple stages.

Installation & Usage

Add this line to your application's Gemfile:

gem 'mina-multistage', require: false

And then execute:

$ bundle

Or install it yourself as:

$ gem install mina-multistage

Require mina/multistage in your config/deploy.rb:

require 'mina/multistage'
require 'mina/bundler'
require 'mina/rails'
require 'mina/git'

...

task setup: :environment do
  ...
end

desc 'Deploys the current version to the server.'
task deploy: :environment do
  ...
end

Then run:

$ bundle exec mina multistage:init

This will create config/deploy/staging.rb and config/deploy/production.rb stage files. Use them to define stage specific configuration.

# config/deploy/staging.rb
set :domain, 'example.com'
set :deploy_to, '/var/www/my_app'
set :repository, 'https://github.com/user/repo'
set :branch, 'master'
set :user, 'www'
set :rails_env, 'staging'

If you receive the following error, make sure that you've required 'mina/multistage' in your config/deploy.rb

$ bundle exec mina multistage:init
mina aborted!
Don't know how to build task 'multistage:init'

Now you can deploy the default stage with:

$ mina deploy # this deploys staging by default

Or specify a stage explicitly:

$ mina staging deploy
$ mina production deploy

Configuration

• stages - array of stages names, the default is the name of all *.rb files from stages_dir
• stages_dir - stages files directory, the default is config/deploy
• default_stage - default stage, the default is staging

If you want to override the default values for any of these options, they should be set before requiring mina/multistage.

# config/deploy.rb

set :stages, %w(development test staging production)
set :stages_dir, 'config/deploy_stages'
set :default_stage, 'development'

require 'mina/multistage'
require 'mina/bundler'
require 'mina/rails'
require 'mina/git'

...

task setup: :environment do
  ...
end

desc 'Deploys the current version to the server.'
task deploy: :environment do
  ...
end
