# What is Ruby?
|
|
|
|
Ruby is a dynamic, reflective, object-oriented, general-purpose, open-source
|
|
programming language. 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 which should be all you need to
|
|
bootstrap most applications. The build will `COPY . /usr/src/app` and `RUN
|
|
bundle install`.
|
|
|
|
You can 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 simple, single file projects, you may find it inconvenient to write a
|
|
complete `Dockerfile`. 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
