Added message to Campfire chatroom for Capistrano deploys

# Gemfile
gem 'capistrano-campfire'
gem 'tinder'

# config/deploy.rb
require 'capistrano/campfire'
require 'tinder'

namespace :campfire do
  desc "Send a message to the campfire chat room"
  task :snitch do
    campfire = Tinder::Campfire.new YOUR_CAMPFIRE_ACCOUNT, :ssl => true, :token => YOUR_CAMPFIRE_TOKEN
    room = campfire.find_room_by_name YOURC_CAMPFIRE_CHATROOM
    snitch_message = fetch(:snitch_message) { ENV['MESSAGE'] || abort('Capfire snitch message is missing. Use set :snitch_message, "Your message"') }
    room.speak(snitch_message)
  end

  desc "Send a message to the campfire chat room about the deploy start"
  task :snitch_begin do
    set :snitch_message, "BEGIN DEPLOY [#{stage.upcase}]: #{ENV['USER']}, #{branch}/#{real_revision[0, 7]} to #{deploy_to}"
    snitch
  end

  desc "Send a message to the campfire chat room about the deploy end"
  task :snitch_end do
    set :snitch_message, "END DEPLOY [#{stage.upcase}]: #{ENV['USER']}, #{branch}/#{real_revision[0, 7]} to #{deploy_to}"
    snitch
  end

  desc "Send a message to the campfire chat roob about the rollback"
  task :snitch_rollback do
    set :snitch_message, "ROLLBACK [#{stage.upcase}]: #{ENV['USER']}, #{latest_revision[0, 7]} to #{previous_revision[0, 7]} on #{deploy_to}"
    snitch
  end
end

before :deploy do
  campfire.snitch_begin unless ENV['QUIET'].to_i > 0
end

after :deploy do
  campfire.snitch_end unless ENV['QUIET'].to_i > 0
end

Permission denied (publickey) error when trying to do cap deploy

My solution was to run in my terminal

ssh-add

Seemed like my there wasn't an identity associated with my ssh public key so Github rejected capistrano attempt to git clone from the deployment server.

Top 3 hosted CI (continuous integration) for Rails apps

Here's my summary of top 3 hosted solutions for Rails continuous integration are:

- https://semaphoreapp.com/features
- https://www.circleci.com/
- Tddium

Tddium looks very configurable and gives power to the commandline, eg. run builds from local console on branches. $15/mth for 10 worker hours.

http://docs.tddium.com/

CircleCI had good reviews and sounded like it runs builds really fast. Like Tddium, it's configurable via a yaml file. No official price plans on website but responded via twitter that theirs plans starts from $19.

http://blog.exceptional.io/news/circleci/

Semaphore selling point's their "simple stupid" approach to CI. Oauth via Github, add collaborators and boom. Runs are every git push and at a price of $14/mth, it seemed the cheapest of 'em lot.

https://semaphoreapp.com/features

My vote is for Semaphore since it's the cheapest and simplest to use for a small project.
