This is not exactly a bug. The simple docker compose YAML that is in our repo points to jekyll/jekyll:latest. The latest image uses ruby version 2.7.0, which is probably what is causing the errors you see. Devdocs is using Ruby 2.6.6. You can change the docker-compose file to use jekyll/jekyll:3.8.6 and it works.
