gcloud 预览应用程序 运行 不会重新构建 docker 文件
gcloud preview app run doesn't re-build docker file
跟随managed VMs tutorial，我想运行本地一些后面的例子。 （就像我对 development/testing 所做的那样。）当我将我的项目部署到云端时，它工作得非常愉快，但是当我 运行 它在本地时 (gcloud preview app run ./app.yaml) 我收到一个导入错误，因为 flask 是未安装/docker 图像未更新。
有没有办法在本地构建和 运行 容器？
设置环境变量GAE_LOCAL_VM_RUNTIME为0:
export GAE_LOCAL_VM_RUNTIME=0
gcloud preview app run app.yaml
此行为在 Cloud SDK RELEASE_NOTES 0.9.71 版中进行了描述：
For several months on the Managed VMs team we've been testing a new mode of
dockerless local development on gcloud that makes developing a module for
Python, Java and Go users similar to development of regular App Engine
applications. This new mode relaxes the sandbox constraints present in the
devappserver for vm: false applications, and does not require Docker to be
installed.
You can currently opt-into this behavior by setting GAE_LOCAL_VM_RUNTIME=1;
In this release of the Cloud SDK, we will be making this behavior the
default for Managed VM users who are using gcloud.
You can still opt-out of this behavior by setting: GAE_LOCAL_VM_RUNTIME=0.
