Ruby 如何在docker容器中成功安装rake和bundle？

我有一个docker文件，它执行以下操作：

RUN apk update && apk add ruby ruby-irb ruby-rake ruby-io-console ruby-bigdecimal ruby-json ruby-bundler

我得到这个错误日志：

$ bundle

[33m`/opt/jenkins` is not writable.
Bundler will use `/tmp/bundler/home/jenkins' as your home directory temporarily.

当我尝试按如下方式安装rake时：

gem install rake -v 10.3.2

作为构建作业中的命令，我得到：

我如何解决这个问题？如何获得

将ruby和rake安装为gem

apk add ruby && gem install rake

您还可以使用ruby/2.4-alpine作为基本映像，以避免手动安装ruby

FROM ruby/2.4-alpine
RUN gem install rake
