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. + +> [wikipedia.org/wiki/Ruby_(programming_language)](https://en.wikipedia.org/wiki/Ruby_(programming_language)) + +JRuby leverages the robustness and speed of the JVM while providing the same +Ruby that you already know and love. +With JRuby you are able to take advantage of real native threads, enhanced +garbage collection, and even import and use java libraries. + +# How to use this image + +## Create a `Dockerfile` in your Ruby app project + + FROM jruby:.1.7.15-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 which should be all you need to +bootstrap most applications.
