有什么线索吗？

Answer 1

1. 修复第一个(如果你的应用程序中没有dockerfile，它应该自动生成。)

   转到部署失败的 ruby​​ 示例文件。 (我的是如下所示的“2-cloud-sql”)

   $ cd 2-cloud-sql

然后我执行了下一个命令。

$ gcloud preview app gen-config --custom

如果你质疑“现在更新？”回答是(是)。然后“app.yaml”文件成为自定义文件，但原始文件保持原样，并制作“dockerfile”。

接下来我被要求更新一些 Cloud SDK 组件，所以在下面编写命令。

$ gcloud components update

我在下面做了

$ bundle install

1. 您的示例应用程序中应该已经有“Dockerfile”。打开看看。

在我的例子中，这 3 个地方(在黄色方 block 中)被缩进并且不自然地转到下一行。~但是在另一个谷歌教程中，没有这样奇怪的行，所以在那种情况下我不需要更改“dockerfile” .请看dockerfile看看下面有没有像我这样改的地方~

Go and check a picture

所以我像这样修复了这些奇怪的部分。

Here is a picture

在“if”之前有一个奇怪的换行，在“&&\”之前也是如此。

修复并保存 Dockerfile 后

我像谷歌指令一样执行了这些命令。

$ RAILS_ENV=production rake assets:precompile


$ gcloud preview app deploy

以上就是我的全部，希望对你有所帮助。
