Supported tags and respective Dockerfile links

The tag details are as follows

Usage

Create a Dockerfile in your Ruby app project

FROM openeuler/distroless-ruby:3.2.2-oe2403lts

RUN bundle config --global frozen 1

WORKDIR /usr/src/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":/usr/src/app -w /usr/src/app openeuler/distroless-ruby:3.2.2-oe2403lts bundle install

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, for example:

$ docker run -it --rm $PWD/example:/usr/src/myapp -w /usr/src/myapp openeuler/distroless-ruby:3.2.2-oe2403lts ruby example.rb

Run Applications as a Non-Root User

For implementation details, refer to the distroless-base-nonroot documentation.
