GCP kms加密env var并通过cloudbuild.yaml将加密密钥传递给谷歌应用引擎

Question

我正在尝试在部署到Google App Engine的RoR应用程序中加密Cloud SQL中的数据库env vars。遵循这个文档https://cloud.google.com/cloud-build/docs/securing-builds/use-encrypted-secrets-credentials

但是，运行gcloud builds submit和gcloud app deploy时出错。两者都出错了：

失败状态：UNKNOWN：错误响应：[4] DEADLINE_EXCEEDED / build步骤0“gcr.io/cloud-builders/gcloud”失败：退出状态1。

然后我检查gcloud builds described显示应用程序未能部署，但是，DATABASE_PASS显示工作/排队。我已将gcloud sdk中的Cloud Build组件增加到1000并测试超时：在cloudbuild.yaml;中，这两个选项都没有改进。

在使用Cloud Build之前，我的应用程序正在运行，但我正在删除凭据和使用加密凭据进行CI / CD管道的需要。另外，想在我的app.yaml中加密多个env var。

 <cloudbuild.yaml>
steps:
- name: 'gcr.io/cloud-builders/gcloud'
  args: ['app','deploy','app-beta.yaml']

- name: 'us.gcr.io/project_ID/image_name'
  #args: [ 'app', 'deploy', 'app-beta.yaml' ]
  secretEnv: [ "DATABASE_PASS" ]


secrets:
- kmsKeyName: projects/Project_id/locations/global/keyRings/Misc/cryptoKeys/Random
  secretEnv: 
      DATABASE_PASS:< base64 encoded encryption>
