部署 Google 的 App Engine flex [nginx 示例] 时出错

Question

我正在尝试 deploy Google's nginx hello world example 通过 App Engine 的灵活环境。我使用的设置与快速入门指南中详述的设置相同，但添加到 app.yaml（文件内容如下）的网络设置除外：

runtime: custom
env: flex
network:
  name: my_network
  subnetwork_name: my_subnet

对于复制，我的确切过程是（来自 GCP 云 shell）：

克隆 Google's example repo,
cd进入nginx目录，
更新 app.yaml 以反映正确的网络设置（见上文），
运行 gcloud app deploy . 或 gcloud beta app deploy ..

结果是错误13：

53db376e88c7: Layer already exists
3baebd9b50ad: Layer already exists
1401df2b50d5: Layer already exists

ERROR: (gcloud.app.deploy) Error Response: [13] An internal error occurred.

我尝试使用不同的健康检查选项进行部署，但收到以下信息：

ERROR: (gcloud.app.deploy) INVALID_ARGUMENT: Legacy health checks are no longer supported for the App Engine Flexible environment. Please remove the 'health_check' section from your app.yaml and configure updated health checks. For instructions on migrating to split health checks see https://cloud.google.com/appengine/docs/flexible/java/migrating-to-split-health-checks

我认为这样做的建议已经过时了。

应用程序本身运行在 docker 容器中很好。欢迎任何建议

我也尝试重现您提到的相同场景，但没有向我抛出任何错误。将网络添加到您的 app.yaml 时，您必须确保使用网络的简称，here.

中提到了这一点

您 app.yaml 中的网络设置应如下所示：

network:
  instance_tag: TAG_NAME
  name: NETWORK_NAME
  subnetwork_name: SUBNETWORK_NAME
  session_affinity: true
  forwarded_ports:
    - PORT
    - HOST_PORT:CONTAINER_PORT
    - PORT/tcp
    - HOST_PORT:CONTAINER_PORT/udp

name 的位置：

Every VM instance in the flexible environment is assigned to a Google Compute Engine network when it is created. Use this setting to specify a network name. Give the short name, not the resource path (for example, default rather than https://www.googleapis.com/compute/v1/projects/my-project/global/networks/default). If you do not specify a network name, instances are assigned to the project's default network (which has the name default). If you want to specify a subnetwork name, you must specify a network name.

对于subnetwork_name：

Optional. You can segment your network and use a custom subnetwork. Ensure that the network name is specified. Give the short name, not the resource path (for example, default rather than https://www.googleapis.com/compute/v1/projects/my-project/global/networks/default/subnetworks/default).The subnetwork must be in the same region as the application.

如果您正在为您的项目使用 VPC 共享网络，这将帮助您做到这一点，您需要做的就是按照给定的步骤一步步进行 here。

Answer 2

Google 支持提供了一个对我有用的解决方案。不过Error 13比较笼统所以YMMV。在您的部署环境中，运行如下：

gcloud config set interactive/hidden true
gcloud app update --service-account=PROJECT_DEFAULT_APP_ENGINE_SA
gcloud app deploy

1 exposes hidden commands/flags 和 2 设置应用程序的活动服务帐户。

当心 - 项目的默认 App Engine SA 获得大量许可，因此可能值得将 App Engine 隔离到其自己的项目以最大限度地降低风险。
