Can I've a Docker file for this project?

I've Ubuntu 22 and it has Ruby 3 and this project supports Ruby 2. I don't have any experience in Ruby so while installing I was having this error, I tried doing some tweaks to Gem file but didn't work.

An error occurred while installing commonmarker (0.17.13), and Bundler cannot
continue.
Make sure that `gem install commonmarker -v '0.17.13' --source
'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  github-pages was resolved to 204, which depends on
    jekyll-commonmark-ghpages was resolved to 0.1.6, which depends on
      jekyll-commonmark was resolved to 1.3.1, which depends on
        commonmarker
The command '/bin/sh -c bundle install' returned a non-zero code: 5

This is the Dockerfile I was trying to make.

FROM ruby:2-alpine

WORKDIR /app

COPY . /app

RUN bundle install

CMD [ "bundle", "exec", "jekyll", "serve" ]

Hi @iamrobins! 👋 Thanks for opening this issue. A dockerfile sounds like a great idea, but unfortunately I don't really have any experience configuring docker for projects and I won't have any development time for this project in which I could learn Docker and contribute what you asking myself in the foreseeable future.

Would you like to contribute the solution yourself? I'll be happy to review and test a PR for it if you take the time to do so! 🙂

Yeah definitely, I've created a Dockerfile with Ruby 3.0 because older ruby versions were not working for me. Are you planning to upgrade the project to Ruby 3.0 with a new Gemfile.lock ?

I found the fix to run it on Ruby 3.0 in this issue #112

[iamrobins]

Hi @jglovier now there is no need to upgrade the project to Ruby 3.0 I have created the Dockerfile which works perfectly with the current state of the project. I've made a PR with 2 lines of instructions in the README. please take a look when you get time.

Thanks again, @iamrobins!! Resolved by #135.
