CapGun

DESCRIPTION

Tell everyone about your releases! Send email notification after Capistrano deployments! Rule the world!

Drop your ActionMailer configuration information into your deploy.rb file, configure recipients for the deployment notifications, and setup the callback task.

Setup and configuration are done entirely inside your deploy.rb file to keep it super simple. Your emails are sent locally from the box performing the deployment, but CapGun queries the server to grab the necessary release info.

This even includes the Net::SMTP TLS hack inside as a vendored dependancy to allow super easy email sending without setting up an MTA.

CONFIG

In your Capistrano config file (usually deploy.rb):

# require cap_gun (the path will depend on where you unpacked or if you are just using it as a gem)
require 'vendor/plugins/cap_gun/lib/cap_gun' # typical Rails vendor/plugins location

# setup action mailer with a hash of options
set :cap_gun_action_mailer_config, {
  :address => "smtp.gmail.com",
  :port => 587,
  :user_name => "[YOUR_USERNAME]@gmail.com",
  :password => "[YOUR_PASSWORD]",
  :authentication => :plain 
}

# define the options for the actual emails that go out -- :recipients is the only required option
set :cap_gun_email_envelope, { 
  :from => "project.deployer@example.com", # Note, don't use the form "Someone project.deploy@example.com" as it'll blow up with ActionMailer 2.3+
  :recipients => %w[joe@example.com, jane@example.com] 
}

# register email as a callback after restart
after "deploy:restart", "cap_gun:email"

# Test everything out by running "cap cap_gun:email"

USAGE

Good news: it just works.

By default CapGun includes info like the user who is deploying and what server its being deployed to. CapGun is biased for git (patches accepted for other SCMs), so it will include details like your current branch, the revisions since last deployment, the current commit being deployed.

Want to make the notifications even better and explain why you're deploying? Just include a comment in the cap command like so, and CapGun will add the comment to the email notification.

cap -s comment="fix for bug #303" deploy

REQUIREMENTS

Capistrano 2+
A Gmail account to send from, or an MTA (mail transport agent) installed locally to send from
Something to deploy

TODO & KNOWN ISSUES

displays the release times in UTC (Capistrano default) - could be flipped to specified time zone
some stuff will probably break on windows - patches welcome
