Question

我是谷歌云的新手，我正在尝试首次部署它。我的第一个部署是Ruby on Rails项目。

我基本上跟随this guide in the google cloud documentation。唯一的区别是我使用自己的项目而不是他们提供的“hello world”项目。

这是我的app.yaml文件

runtime: custom
vm: true
entrypoint: bundle exec rackup -p 8080 -E production config.ru
resources:
  cpu: 0.5
  memory_gb: 1.3
  disk_size_gb: 10

当我转到我的项目目录并运行gcloud preview app deploy时，它会启动部署但最终会超时。它给出了错误(gcloud.preview.app.deploy) Error Response: [4] DEADLINE_EXCEEDED。

进行一些研究我发现gcloud preview app deploy与--verbosity debug一起运行会提供额外的调试信息，但它无法帮助我找到导致其超时的内容。

这是控制台日志的最后一块。

这是最远的，但有时它会在它超时之前安装宝石的中途，有时它甚至不会安装宝石。

如何阻止这种情况发生？

Answer 1

Docker构建有一个10分钟的默认超时（runtime: custom App Engine构建工作的机制）。您可以通过运行gcloud config set app/cloud_build_timeout [NUMBER OF SECONDS]来增加此功能。

您也可以通过自己执行构建来解决这个问题：

docker build . -t gcr.io/myapp/myimage
gcloud docker push gcr.io/myapp/myimage
gcloud preview app deploy app.yaml --image-url=gcr.io/myapp/myimage

但是，一般来说，你的Docker构建不应该花这么长时间。通常情况下，拥有一个已经内置了所有依赖项的基本映像会更好，并且只需从该映像派生最终版本并安装您的应用程序。这样，您的构建将更快。

Answer 2

总体请求超时时，会引发此错误。

任务队列请求的执行限制为10分钟。您可以通过输入gcloud config set app/cloud_build_timeout [TIMEOUT_SECONDS]

来增加Google Cloud Shell的超时限制

示例

gcloud config set app/cloud_build_timeout 1000

每次我尝试部署时都会得到 - （gcloud.preview.app.deploy）错误响应：[4] DEADLINE_EXCEEDED
