嘗試在 docker 下運行 rails 控制臺時遇到一些問題。所有其他 rails 命令都按預期作業，但控制臺沒有。

并且還docker-compose up照常作業。
我使用過許多類似的 docker 設定，沒有任何問題。我的想法不多了。
環境設定
- 寶石在 ./bundle 下
- 碼頭工人撰寫版本 1.29.2
- 紅寶石 2.7
- 導軌 6.1.4.4

非常感謝任何幫助。

每次執行docker-compose run時都會創建一個新容器，因此以前安裝的 gem 不再可用。
為了解決您的問題，您可以bundle install在 Dockerfile 中運行，將 gems 安裝在 app 檔案夾中，bundle install --path vendor/bundle 或者安裝默認情況下用于存盤 gems 的目錄包，通常/usr/local/bundle

我發現這個問題是在 spring 4.0 ( issue 669 ) 中引入的。Bundle env 變數被忽略。
降級到spring 3.1.1解決了這個問題。

gem 'spring', '~> 3.1.1'
