由于超时，部署 AppEngine 版本失败

Question

我正在尝试部署到 Google AppEngine。 （更准确地说：托管虚拟机。）

之前，我尝试在 Windows 中使用云端构建的 Docker 执行此操作，但失败了（请参阅 StackOverflow question）；所以现在我在 Linux 上尝试了，Docker 在本地构建。

这也失败了，但原因不同。它在各种 Linux 开发机器上始终失败。当我们从 Google Cloud 中的 Linux 虚拟机运行相同的命令时，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

因为我无法评论而回答-

我在使用 gcloud 进行部署时遇到过类似的超时/错误，我总是通过升级 gcloud 工具本身或有时升级 SDK 来解决这个问题。您运行的是最新版本的 gcloud 吗？

Answer 2

你的构建失败了，这行：

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

这可能是从 gcloud 到您的（本地）docker 守护进程的 HTTP 请求。 docker 客户端（即 gcloud）将 docker build 上下文（调用 docker build 的目录的压缩包）发送到 docker 守护进程。看到写超时很奇怪。您的项目是否过大（例如 GiB+）？您是否尝试过在同一目录上运行 vanilla docker build？

您可以尝试--verbosity debug 以获取更多调试信息。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）。
