RubyBuildInfo 
Rack middleware to output build information such as version control, bundled gems, and specified files to JSON.
Installation / Usage
Add this line to your application's Gemfile:
gem 'ruby_build_info'
And then execute:
$ bundle
Or install it yourself as:
$ gem install ruby_build_info
In your config\environment\development.rb or environment file of your choosing:
config.middleware.use(RubyBuildInfo::Middleware)
By default this will output Git revision if available, and output of bundle show.
You can specify an array optional file paths, such as version files.
config.middleware.use(RubyBuildInfo::Middleware, file_paths: ['../custom_file_1', '../custom_file_2'])
You can also provide an optional token in your environment file. When provided, you must pass the token as a parameter to access the endpoint.
config.middleware.use(RubyBuildInfo::Middleware, token: 'foo')
http://localhost:3000/build_info?token=foo
Go to /build_info in your Ruby application to see output, supplying token paramater if configured.
