Send notifications for the changes deployed in each build, compared to the previous build. It is a good practise to create GIT tags for each deployment. DeployChangesNotifier compares the latest deployed tag with the previous deployed tag and sends the list of new commits deployed to a Slack channel.

Add this line to your application's Gemfile:

gem 'deploy_changes_notifier'

And then execute:

$ bundle

Or install it yourself as:

$ gem install deploy_changes_notifier

Or use the github url:

gem 'deploy_changes_notifier', git: "https://github.com/subodhkhanduri1/deploy_changes_notifier.git"

Require the gem

require 'deploy_changes'

Send notification

notifier = DeployChanges::Notifier.new do |config|
  config.git_repo_url = 'https://github.com/<your_organization>/<your_repo_name>'
  # Tags are expected to be numbered in sequential order. Build numbers would work nicely.
  config.tag_prefix = 'app-prd-'
  config.deploy_job_name = '<your_deploy_job_name>'
  config.deploy_job_build_number = 3 # The latest deploy job build number
  config.slack_channel = 'Production'
  config.slack_bot_api_token = '<some_token>'
end

notifier.send_deploy_changes_notification

To supply the config parameters to a script, pass in environment variables with the same name as the config variables. If you pass in environment variables, there is no need to pass config variables in the constructor.

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
