Capistrano task to notify Ratchet.io about deployment

deploy.rb

# I am trying out Ratchet.io and I want to add their deployment notification to my
# normal capistrano deployment process. Here is my first working attempt.

# Add this task to your deploy.rb
namespace :rollbar do
  task :notify, :roles => [:web] do
    set :revision, `git log -n 1 --pretty=format:"%H"`
    set :local_user, `whoami`
    set :rollbar_token, YOUR_ACCESS_TOKEN
    rails_env = fetch(:rails_env, 'production')
    run "curl https://api.rollbar.com/api/1/deploy/ -F access_token=#{rollbar_token} -F environment=#{rails_env} -F revision=#{revision} -F local_username=#{local_user} >/dev/null 2>&1", :once => true
  end
end

# Then add this task to your deployment flow, i.e.
after  "deploy:restart", "rollbar:notify"

Whoa, I just saw the comments and updated the gist accordingly. Thanks @brianr & @ferblape !
