gcloud nodejs cloudbuild.yaml陷入无限循环

Question

当我使用 node server.js 在本地运行它时，我有一个运行良好的 node.js 网站。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，并授予了我的“@cloudbuild.gserviceaccount.com”帐户应用引擎部署者角色权限。

我还在我的仓库中添加了一个 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，但在我看来会导致构建的无限循环？例如，开始我的构建日志看起来像这样（当前没有运行）：

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

但是这个构建的某些东西不断触发新构建？在我的本地计算机终端中，运行gcloud app deploy 得到的输出不断触发新的构建：

$ gcloud app deploy

继续，现在我有更多的构建：

我的 app.yaml：

runtime: custom
env: flex
manual_scaling:
  instances: 2

这与我的 cloudbuild.yaml 文件有关吗？我的文件夹中没有 dockerfile

Answer 1

“这不是错误；这是一项功能！”但它没有记录，或者我没有找到在哪里！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cloudbuild.yaml 文件或Dockerfile 来描述容器创建。这个容器是用 Cloud Build 创建的。

关于信息，如果你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，在您的情况下，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，该文件调用 Cloud Build 来构建容器，并在部署的参数中使用 cloudbuild.yaml 文件。 ....（循环！）

好的，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 命令中设置此名称
• 像这样更新您的 cloudbuild.yaml 部署步骤

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