Question

我正在尝试部署到Google AppEngine。（更确切地说：托管VM。）

早些时候，我尝试在Windows中执行此操作，Docker内置于云端，但失败了（请参阅StackOverflow question）;所以现在我尝试从Linux开始，在本地构建Docker。

这也失败了，但原因不同。它从各种Linux开发机器一直失败。当我们从Google Cloud中的Linux VM运行相同的命令时，它会成功。

我可以做些什么来部署它？

gcloud preview app deploy  /shared/yaml-war/app.yaml --version=joshua20160317a --project=mytest-test1

Linux控制台输出

gcloud preview app deploy  /shared/yaml-war/app.yaml --version=joshua20160316a --project=mytest-test1WARNING: The `gcloud preview app` surface is rapidly improving. Look out for
changing flags and new commands before the transition out of the `preview`
component. These changes will be documented in the Cloud SDK release notes
<https://dl.google.com/dl/cloudsdk/release/RELEASE_NOTES> and via deprecation notices for changing commands.

If you would like to avoid changing behavior, please pin to a fixed version of
the Google Cloud SDK as described under the "Alternative Methods" section of the
Cloud SDK web site: <https://cloud.google.com/sdk/#alternative>.

Answer 1

我无法回答 -

我在使用gcloud进行部署时遇到了类似的超时/错误，并且通过升级gcloud工具本身或者有时升级SDK总是为我修复。您是否正在运行最新版本的gcloud？

Answer 2

您的构建失败了这一行：

ERROR: gcloud crashed (SSLError): The write operation timed out

这可能是从gcloud到你的（本地）docker守护进程的HTTP请求。 docker客户端（即gcloud）正在将docker构建上下文（调用docker build的目录的tarball）发送到docker守护程序。看到写入超时是很奇怪的。您的项目是否过大（例如GiB +）？您是否尝试在同一目录中运行vanilla docker build？

您可以尝试--verbosity debug获取其他调试信息。实际上，我认为这只会打印出您在日志文件中找到的内容（感谢您粘贴日志文件）。

由于超时而无法部署AppEngine版本
