Overview

Simple Example:

require 'kapost_deploy/task'

KapostDeploy::Task.new do |config|
  config.app = 'cabbage-democ'
  config.to = 'cabbage-prodc'

  config.after do
    puts "It's Miller time"
  end
end

A slightly more complex example which will create 6 rake tasks: before_stage, stage, after_stage, before_promote, promote, after_promote

KapostDeploy::Task.new(:stage) do |config|
  config.app = 'cabbage-stagingc'
  config.to = %w[cabbage-sandboxc cabbage-democ]

  config.after do
    sleep 60*2 # wait for dynos to restart
    notifier.ping "The eagle has landed. [Go validate](https://testbed.sandbox.com/dashboard)!"
    Launchy.open("https://testbed.sandbox.com/dashboard")
  end
end

KapostDeploy::Task.new(:promote) do |config|
  config.app = 'cabbage-sandbox1c'
  config.to = 'cabbage-prodc'

  config.before do
    puts 'Are you sure you did x, y, and z? yes/no: '
    confirm = gets.strip
    exit(1) unless confirm.downcase == 'yes'
  end
end
