What is Ruby
Ruby is a dynamic, reflective, object-oriented, general-purpose programming language. It was designed and developed in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan.
According to its authors, Ruby was influenced by Perl, Smalltalk, Eiffel, Ada, and Lisp. It supports multiple programming paradigms, including functional, object-oriented, and imperative. It also has a dynamic type system and automatic memory management.
How to use this image
Create a Dockerfile in your ruby app project
FROM ruby:2.1.2-onbuild
CMD ["./your-daemon-or-script.rb"]
Put this file in the root of your app, next to the Gemfile.
This image includes multiple ONBUILD triggers so that should be all that you need to bootstrap most applications. The build will ADD . /usr/src/app and RUN bundle install.
Then build and run the ruby image.
docker build -t my-ruby-app .
docker run -it --name my-running-script my-ruby-app
Run a single ruby script
For many single file projects, it may not be convenient to write a Dockerfile for your project. In such cases, you can run a ruby script by using the ruby docker image directly.
docker run -it --rm --name my-running-script -v "$(pwd)":/usr/src/myapp -w /usr/src/myapp ruby:2.1.2 ruby your-daemon-or-script.rb

Contributing
If you want to contribute new features or updates, we are always thrilled to receive pull requests, and do our best to process them as fast as possible.
We recommend discussing your plans through a GitHub issue before starting to code - especially for more ambitious contributions. This gives other contributors a chance to point you in the right direction, give feedback on your design, and maybe point out if someone else is working on the same thing.
