gcloud nodejs cloudbuild.yaml陷入死循环

Question

我有一个node.js网站，当我用node server.js在本地运行它时，它运行得很好。我正在尝试使用GCP在线部署它。我创建了一个项目，启用了应用引擎API，并为我的'@cloudbuild.gserviceaccount.com‘账户提供了应用引擎部署者角色权限。

我还在我的存储库中添加了一个cloudbuild.yaml文件：

steps:
- name: "gcr.io/cloud-builders/gcloud"
  args: ["app", "deploy"]

现在，如果我运行gcloud app deploy，我的构建会被触发，但似乎会导致构建的无限循环？例如，启动我的构建日志如下所示(当前未运行任何内容)：

​

​

我运行gcloud app deploy，它开始一个新的构建(1a19d9ba)：

​

​

但是这个构建的某些东西一直在触发新的构建吗？在我本地的计算机终端中，我运行gcloud app deploy得到的输出不断触发新的构建：

$ gcloud app deploy

这样继续下去，现在我有了更多的构建：

​

我的app.yaml：

runtime: custom
env: flex
manual_scaling:
  instances: 2

是不是我的cloudbuild.yaml文件有问题？我的文件夹中没有dockerfile

Answer 1

“这不是一个bug，而是一个特性！”但是它没有记录，或者我找不到它在哪里！实际上，使用App Engine Flex自定义运行时，您将创建一个容器。您可以定义一个cloudbuild.yaml文件或一个Dockerfile来描述容器的创建。这个容器是用Cloud Build创建的。

对于信息，如果您设置了特定的语言运行时，Buildpack用于创建容器，仍然在Cloud Build上；但是不再需要Dockerfile

因此，在您的案例中，正如您所描述的，您有一个部署App Engine flex自定义运行时的cloudbuild.yaml文件，它调用云构建来构建容器，其中的cloudbuild.yaml文件包含在部署的参数中……(循环！)

现在，如何解决这个问题?2个解决方案

• 将cloudbuild.yaml文件的名称更改为与此默认命名不匹配(例如cloudbuild-noloop.yaml)。在触发器配置或gcloud builds submit --config=cloudbuild-noloop.yaml command
• Update your cloudbuild.yaml deploy步骤中设置此名称，如以下

所示

steps:
- name: "gcr.io/cloud-builders/gcloud"
  args: ["app", "deploy","--ignore-file=cloudbuild.yaml"]
