I have been trying to create a docker image and run the ruby files
Following is the code for creating the docker image
FROM ruby:3
WORKDIR /app
COPY Gemfile Gemfile.lock ./
RUN gem install bundler && \
bundle config --global frozen 1 && \
bundle install
RUN gem install extensions
COPY app.rb config.ru database.rb utils.rb thin.rb ./
EXPOSE 8080
CMD exec thin -R config.ru -p 8080 start
I also tried CMD bundle exec thin start instead of last command above.
I then execute the following command to build the image
sudo docker build -t project3 .
And the build is successful.
But when I run docker run -p 8080:8080 project3
I receive the following error
mayuresh@mayuresh-Lenovo-ideapad-330-15IKB:~/Softwares/CS291_project3$ sudo docker run -p 8080:8080 project3

I tried implementing the code mentioned on Link1 Link2
Also, I would like to mention that earlier I have dockerized many projects with similar docker file, but I don't understand what could be the problem associated in this approach.
Thanks for help!
The release history for mustermann says that support for ruby v3.0.0 was added in v1.1.0.
You are using ruby v3.0.0 with mustermann v1.0.3.
Either downgrade ruby to 2.7, or upgrade mustermann to 1.1.0+
