如何在Docker容器中成功安裝rake和bundle？

Question

我有一個執行以下操作的docker文件：

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

我收到此錯誤日志：

$ bundle

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

當我嘗試如下安裝rake時：

gem install rake -v 10.3.2

作為構建作業中的命令，我得到：

安裝紅寶石和耙作為寶石。

apk add ruby && gem install rake

您也可以將ruby / 2.4-alpine用作基本映像，以避免手動安裝ruby。

FROM ruby/2.4-alpine
RUN gem install rake
