我试图容器化我的Rails应用程序，并通过docker-compose启动它。该应用程序通过docker-compose build构建良好，但当试图启动时，它失败了:
$ docker-compose up

puma | /usr/local/bundle/gems/bootsnap-1.10.3/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:15:in `require': cannot load such file -- nokogiri (LoadError)
我特别纠结于最后一行:
1.10.3/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:15:in `require': cannot load such file -- nokogiri (LoadError)
我的Dockerfile如下:
# syntax=docker/dockerfile:1
FROM ruby:3.0.4
RUN apt-get update && apt-get install -y nodejs postgresql-client zlib1g-dev liblzma-dev patch
RUN gem install nokogiri --platform=ruby
WORKDIR /myapp
COPY Gemfile /myapp/Gemfile
COPY Gemfile.lock /myapp/Gemfile.lock
RUN bundle install
# Add a script to be executed every time the container starts.
COPY entrypoint.sh /usr/bin/
RUN chmod +x /usr/bin/entrypoint.sh
ENTRYPOINT ["entrypoint.sh"]
EXPOSE 3000
# Configure the main process to run when running the image
CMD ["rails", "server", "-b", "0.0.0.0"]
我试着遵循这里的建议，注意到Docker是用Debian构建镜像的。但是，这似乎不起作用。
我也看到了这篇文章，但在这种情况下，我不是用Alpine Linux构建，我使用默认的ruby镜像，它似乎在Debian上运行。我也尝试在我的M1 macOS(11.3.1)机器上启动。
这里有什么建议或技巧吗?我对通过Docker构建Rails应用程序比较陌生，任何提示都将非常感激🙇🏻。
