Ruby 2.5 Container Image

Redistributable SLSA Provenance: Available


Ruby is a dynamic, reflective, object-oriented, general-purpose, open-source programming language. It supports multiple programming paradigms, including functional, object-oriented, and imperative. It also has a dynamic type system and automatic memory management.


To deploy an application, install dependencies, copy the sources, and configure the application's main script:


# displays an error message if Gemfile and Gemfile.lock are not in sync
RUN bundle config --global frozen 1


COPY Gemfile Gemfile.lock ./
RUN bundle install

COPY . .

CMD [ "ruby", "./main-script.rb" ]

Build and run the container image:

$ podman build -t my-ruby-app .
$ podman run -it --rm my-ruby-app

The example above assumes that there is a Gemfile.lock file in the application directory. To generate a Gemfile.lock file, use the following command:

$ podman run --rm -v "$PWD":/app:Z -w /app bundle lock

To run a single script inside a container, use the following command:

$ podman run --rm -v "$PWD":/app:Z -w /app ruby script.rb


The Ruby image sets the locale environment variable LANG to C.UTF-8.

Additional tools

In addition to the standard SLE BCI development packages the following additional tools are included in the image:

  • gcc-c++
