如何在不计费的情况下在灵活的环境中部署 GAE 项目？

Question

我一直在使用 Flask 和其他第三方库开发一些 REST 服务，我想将它部署到灵活环境中的 GAE。我通常部署到 GAE 标准环境，但我想尝试新的灵活环境。目前我希望在不启用计费的情况下部署到灵活的环境，Google 支持向我保证可以在不启用计费的情况下通过 GAE 灵活的环境进行部署。

运行我的代码在本地工作正常，并且有以下 yaml 文件：

runtime: python
env: flex
entrypoint: gunicorn -b :$PORT whereismybus230.starter:app

runtime_config:
  python_version: 3

所以我通过 Google 云控制台网页（像往常一样）创建了一个新项目，并在我的本地机器上创建了一个新的 gcloud 配置文件，所以我将它部署到这个新项目。然后我运行:

gcloud app deploy --verbosity=info

我知道正在构建一个 docker 图像，在某个时候它会被推送到计算引擎，但它在几分钟后失败了：

使用IAM服务，我确定我的账户是项目的所有者，甚至检查了所有权限。由于灵活的环境依赖于计算引擎 (VM)，我尝试从网页上进行检查，它告诉我需要启用计费才能使用此功能。

我做错了什么吗？谢谢！

来自 App Engine Pricing:

Instances within the standard environment have access to a daily limit of resource usage that is provided at no charge defined by a set of quotas. Beyond that level, applications will incur charges as outlined below. To control your application costs, you can set a spending limit. To estimate costs for the standard environment, use the pricing calculator.

Go to the pricing calculator

For instances within the flexible environment, services and APIs are priced as described below.

来自Flexible environment instances：

Applications running in the App Engine flexible environment are deployed to virtual machine types that you specify. This table summarizes the hourly billing rates of the various computing resources:
US
Resource  Unit    Unit cost
vCPU  per core hour   [=10=].0526
Memory    per GB hour     [=10=].0071
Persistent disk   per GB per month    [=10=].0400

与标准环境不同，弹性环境没有免费配额。这符合您的观察，即开发人员控制台需要为运行 GAE flex 实例启用计费。

如果不启用计费功能，您可能能够部署您的应用程序（但实际上并没有为它启动 GAE 实例，所以不确定它的用处，因为您想尝试一下）通过使用 --no-promote 选项：

--promote

Promote the deployed version to receive all traffic.

True by default. To change the default behavior for your current environment, run:
  $ gcloud config set app/promote_by_default false
Overrides the default promote_by_default property value for this command invocation. Use --no-promote to disable.

旁注：当您遇到问题时，您可能还想使用 --verbosity=debug 来获取有关故障的更多相关信息。
