Mina multideploy

Useful tool for parallel deploying on multiple servers with mina.

How it works

This gem will help you deploy the application on multiple servers in parallel. It takes original mina deploy.rb file, changes application_name, domain and starts deploying process.

Installation

Add this line to your application's Gemfile:

gem 'mina-multideploy'

And then execute:

bundle install

Or install it yourself as:

gem install mina-multideploy

Getting Started

Start off by generating a configuration file:

bundle exec rails multideploy:init

It should give you a file in:

config/initializers/multideploy.rb

It should look something like this:

return unless defined? Mina::Multideploy

Mina::Multideploy.configure do |config|
  config.servers = {}
  # Default velues
  # config.original = 'config/deploy.rb'
  # config.w_dir = 'tmp/deploy'
end

Configuration

servers - hash at format domain => array of application_name's.

Example:

config.servers = {
  '84.155.207.209' => %w[carghana caryange cartanzania]
  '105.87.69.69'   => %w[poster]
  '48.84.207.183'  => %w[codica timebot]
}

It means that your code will be deployed to 3 servers, and there can be several applications on one server.

original - path to the original mina deploy.rb file which will be taken as a basic.

w_dir - path to directory where temoporary files and logs will be created.

Available features

After you have configured servers at config/initializers/multideploy.rb you can start deploying in two ways.

Semi-automatic deploy (recomended for first deploy)

Run this command:

bundle exec rails multideploy:prepare

You will get file servers_deploy.rb at working directory (tmp/deploy by default). Check it and run ruby ./tmp/deploy/server_deploy.rb.

Automatic deploy

Run this command:

bundle exec rails multideploy:start

It will make the same as multideploy:prepare, but the deployment will start automatically.

Additional information

all scripts are updated according config file before launch multideploy:prepare and multideploy:start
add public SSH key, so you can login to server without password. Run ssh-copy-id user@$host
