⁠About this image

This image is based on the official Ruby⁠ image for Docker. This image has been updated with the official repository packages to the latest available version. Also, the current Node.js LTS version⁠ has been added and the latest stable version for Yarn⁠.

⁠How to use this image

⁠Create a Dockerfile in your Ruby app project

FROM speedyrails/ruby:2.4.0

# throw errors if Gemfile has been modified since Gemfile.lock
RUN bundle config --global frozen 1

WORKDIR /app

COPY Gemfile Gemfile.lock ./
RUN bundle install

COPY . .

CMD ["./your-daemon-or-script.rb"]

Put this file in the root of your app, next to the Gemfile.

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

Generate a Gemfile.lock

The above example Dockerfile expects a Gemfile.lock in your app directory. This docker run will help you generate one. Run it in the root of your app, next to the Gemfile:

docker run --rm -v "$PWD":/app -w /app speedyrails/ruby:2.4.0 bundle install
