Capistrano deployment email notifier for Rails 3

 

Do you need to send email notifications after application deployments?

 

Christopher Sexton developed a Simple Capistrano email notifier for rails. You can find details at http://www.codeography.com/2010/03/24/simple-capistrano-email-notifier-for-rails.html.

 

Here is Rails 3 port of the notifier.

 

The notifier sends an email after application deployment has been completed.

 

How to use it?

 

 1. Add this file to config/deploy folder.

 2. Update the file with your google credentials and from email address.

 3. Add the following content to config/deploy.rb.

 

    require 'config/deploy/cap_notify.rb'

 

    # add email addresses for people who should receive deployment notifications

    set :notify_emails, ["EMAIL1@YOURDOMAIN.COM", "EMAIL2@YOURDOMAIN.COM"]

 

    after :deploy, 'deploy:send_notification'

 

    # Create task to send a notification

    namespace :deploy do

      desc "Send email notification"

      task :send_notification do

        Notifier.deploy_notification(self).deliver

      end

    end

 

 4. Update deploy.rb with destination email addresses for the notifications.

 5. To test run this command:

 

    cap deploy:send_notification

 

=end

 

require "action_mailer"

 

ActionMailer::Base.delivery_method = :smtp

ActionMailer::Base.smtp_settings = {

  :enable_starttls_auto => true,

  :tls => true,

  :address => "smtp.gmail.com",

  :port => 587,

  :domain => "gmail.com",

  :authentication => "plain",

  :user_name => "YOUR USER NAME",

  :password => "YOUR PASSWORD"

}

 

class Notifier < ActionMailer::Base

  default :from => "YOUR FROM EMAIL"

 

  def deploy_notification(cap_vars)

    now = Time.now

    msg = "Performed a deploy operation on #{now.strftime("%m/%d/%Y")} at #{now.strftime("%I:%M %p")} to #{cap_vars.host}"

   

    mail(:to => cap_vars.notify_emails,

         :subject => "Deployed #{cap_vars.application} to #{cap_vars.stage}") do |format|

      format.text { render :text => msg}

      format.html { render :text => "<p>" + msg + "<\p>"}

    end

  end

end
