我是 Google 云的新手，我正在尝试对其进行首次部署。我的第一个部署是 Ruby on Rails 项目。

我基本上是在关注this guide in the google cloud documentation .唯一的区别是我使用的是我自己的项目，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，它开始部署但似乎最终超时。它给出了错误 (gcloud.preview.app.deploy) Error Response: [4] DEADLINE_EXCEEDED。

做一些研究我发现使用 --verbosity debug 运行 gcloud preview app deploy 提供了额外的调试信息，但它没有帮助我找到导致它超时的原因。

这是控制台日志的最后一 block 。

这是它走得最远的地方，但有时它会在超时之前安装 gems，而其他时候它甚至没有安装 gems。

我怎样才能阻止这种情况发生？

最佳答案

Docker 构建有 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] 来增加它。

您也可以通过自己执行构建来变通:

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，您的 Docker 构建不应花费这么长时间。通常最好有一个已内置所有依赖项的基础镜像，并且只需从该镜像派生最终构建并安装您的应用程序。这样，您的构建会更快。
