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。

Post-install message from rdoc:
Depending on your version of ruby, you may need to install ruby rdoc/ri data:
<= 1.8.6 : unsupported
= 1.8.7 : gem install rdoc-data; rdoc-data --install
= 1.9.1 : gem install rdoc-data; rdoc-data --install
>= 1.9.2 : nothing to do! Yay!

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?
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
