使用 terraform 在 GCP 作曲家中因运行状况检查错误而失败

Question

我试图使用 terraform 在 GCP 中创建 Cloud Composer。我使用的是 terraform 版本 Terraform v0.12.5。但我无法使用 terraform 启动实例。

我收到以下错误

Error: Error waiting to create Environment: Error waiting for Creating Environment: Error code 3, message: Http error status code: 400

在 GCP 平台上创建 Composer 没有任何问题。使用 terraform 创建时，需要进行健康检查。

我已经在我的 GCP cloudshell Terraform 二进制文件中测试了您当前的用户案例，到目前为止没有出现任何问题，Composer 环境已成功创建：

$ terraform -v                                                                                                                                                                                          
Terraform v0.12.9
+ provider.google v3.1.0
+ provider.google-beta v3.1.0

我的一些担忧：

您报告的问题可能与使用旧版运行状况检查有关，这些检查基本上已弃用并由 split health checks 取代：

自 2019 年 9 月 15 日起，如果您使用的是旧版运行状况检查， 您的应用程序将继续运行并接收运行状况检查，但 您将无法部署应用程序的新版本。

你没有指定任何关于你的 Terraform GCP provider 版本的信息部分，我想这个问题可以隐藏在那里，正如我在这个 Changelog 中看到的那样，split_health_checks 在 google_app_engine_application.feature_settings 中被启用，因为3.0.0-beta.1已发布。

请随意添加更多见解，以支持您解决当前问题。
