我一直在尝试添加一个新的 App Engine Module使用托管 VM 而不是默认的 GAE 沙箱。目的是提供一个模块，我可以在其中运行更新版本的 SciPy 和 NumPy，我的面向用户的模块可以调用这些模块。 我已经在本地成功构建并运行了我的 Docker 镜像/容器，但是当我尝试部署到 Google 服务器上的自定义版本时遇到了很多问题。
以下是托管 VM 模块实例的串行控制台输出，由于似乎超出我控制的问题，该实例继续重启。
还有其他人遇到过这些吗？我在配置/部署过程中遗漏了什么吗？
FWIW:我已经使用 GAE 好几年了，甚至在我在 Google 期间也为它做出了贡献。我也有使用模块和 Docker 的经验。托管 VM 的文档和工具目前似乎还很不成熟，我已经筋疲力尽了。我需要帮助。

这个答案大部分是正确的，但是根据 curl 推断图像不存在是有缺陷的。 python-compat应该适合你，但是 python也是一个有效的图像，从运行 docker pull gcr.io/google_appengine/python 可以看出:
$ docker pull gcr.io/google_appengine/python

与贡献者讨论 jonparrott在 github repo 上查看 gcr.io/google_appengine/python docker 图像，各种 python 托管 VM/自定义运行时 docker 图像的关系是 clarified in a comment .
因此，我认为您在此处看到的问题(假设 VM 无法变得健康)可能与您从中获取的图像、您的 Dockerfile、您的应用程序代码或基础架构有关。前三个比最后一个更有可能，但这并非不可想象。似乎“Untar re-exec error: exit status 1: output: unexpected EOF”错误是串行控制台输出期间问题的第一个外在表现。
这可能值得放入 Google Cloud Platform Public Issue Tracker 的问题报告中以及您的 Dockerfile、您的应用程序代码(如果需要)、时间范围(如果它只是暂时发生)等信息。
原始答案
如果您检查容器注册表，您尝试获取的图像 FROM不存在:

python 运行时实际存在的容器注册表镜像是:
gcr.io/google_appengine/python-compat
这应该是解决部署失败的关键。
