Mina::Proteus

Plugin for Mina that adds support for multiple stages and multiple apps to Mina, specifically built for Hanami ruby framework. This gem is based on endoze's mina-multistage gem, huge thanks to him!

Installation & Usage

Add this line to your application's Gemfile:

gem 'mina-proteus', require: false

And then execute:

$ bundle install

Or install it yourself as:

$ gem install mina-proteus

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

# config/deploy.rb

require 'mina/proteus'
require 'mina/bundler'
require 'mina/git'

...

task setup: do
  ...
end

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

You then need to specify your hanami apps like this:

# config/deploy.rb

set :hanami_apps, %w(app1 app2 app3)

That's the only required parameter, optional parameters are:

# config/deploy.rb

set :stages, %w(staging production)   #specify your stages
set :stages_dir, 'config/deploy'      #specify which directory will have all the configurations files
set :default_stage, 'staging'         #specify your default stage

#this is used to deploy a single application in a specific environment
set :bundle_prefix, -> { %{HANAMI_ENV="#{fetch(:current_stage)}" HANAMI_APPS="#{fetch(:current_app)}" #{fetch(:bundle_bin)} exec} }

Note that current_stage and current_app are respectively the stage and the application being called.

Then to create every file run:

$ bundle exec mina proteus:init

This will create config/deploy/staging.rb and config/deploy/production.rb stage files and config/deploy/staging/app1.rb, config/deploy/staging/app1.rb, etc. Use them to define stage and app specific configuration.

Now you can deploy the default stage with:

$ mina <APP-NAME> deploy # this deploys to :default_stage

Or specify a stage explicitly:

$ mina staging <APP-NAME> deploy
$ mina production <APP-NAME> deploy
