Docker 运行给出错误 `initialize': wrong number of arguments (given 2, expected 1) (ArgumentError)

Question

我一直在尝试创建一个 docker 映像并运行 ruby​​ 文件

以下是创建docker镜像的代码

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

我也尝试了CMD bundle exec thin start，而不是上面的最后一个命令。

然后我执行下面的命令来构建镜像

sudo docker build -t project3 .

并且构建成功。

但是当我运行docker run -p 8080:8080 project3

我收到以下错误

我尝试实现上面提到的代码 Link1 Link2

另外，我想提一下，之前我已经使用类似的 docker 文件对许多项目进行了 docker 化，但我不明白这种方法可能存在什么问题。

感谢您的帮助！

release history for mustermann 表示在 v1.1.0 中添加了对 ruby​​ v3.0.0 的支持。

您正在使用 ruby​​ v3.0.0 和 mustermann v1.0.3。

要么将 ruby​​ 降级到 2.7，要么将 mustermann 升级到 1.1.0+
