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



我是谷歌云的新手,我正在尝试对它进行第一次部署。我的第一次部署是一个RubyonRails项目。

我基本上遵循谷歌云文档中的这个指南。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"你好世界"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,但似乎最终会超时。它给出了错误(gcloud.preview.app.deploy) Error Response: [4] DEADLINE_EXCEEDED

在做一些研究时,我发现用--verbosity debug运行gcloud preview app deploy会提供额外的调试信息,但这并不能帮助我找到导致它超时的原因。

这是控制台日志的最后一块。

这是它走得最远的一次,但有时它在安装宝石的中途就超时了,有时甚至还没有安装宝石。

我如何才能阻止这种情况的发生?

Docker构建(runtime: custom应用程序引擎构建的机制)默认超时10分钟。您可以通过运行gcloud config set app/cloud_build_timeout [NUMBER OF SECONDS]来增加此值。

您也可以通过自己执行构建来解决问题:

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

然而,一般来说,Docker构建不应该花费这么长时间。通常最好是有一个已经内置了所有依赖项的基本映像,然后从该映像派生出最终构建并安装您的应用程序。这样,你的构建会更快。

当整个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。你可以在谷歌云外壳上输入gcloud config set app/cloud_build_timeout [TIMEOUT_SECONDS] 来增加这个超时限制

示例

gcloud config set app/cloud_build_timeout 1000
