使用 Deployment Manager 创建 compute.v1.instanceTemplate 时出现神秘的缺失字段错误

我正在尝试使用部署管理器（v2）创建一个compute.v1.instanceTemplate，但是出现以下错误：

Unexpected response from resource of type compute.v1.instanceTemplate: 400 {statusMessage=Bad Request, errors=[{message=Invalid value for field 'resource.properties': ''.  Instance Templates must provide instance properties., domain=global, reason=invalid}]}

我猜它抱怨缺少某个属性，但我无论如何也想不出是哪一个。我查看了实例模板资源和高级部署 例子，而我没有似乎遗漏了什么。不过，我很高兴被证明是错的。

以下是通过 获取的完整资源gcloud deployment-manager deployments describe --log-http name：

下面是一个更加人性化的版本finalProperties：

canIpForward: true
disks:
- autoDelete: true
  boot: true
  deviceName: boot
  initializeParams:
    diskSizeGb: 10
    diskType: pd-standard

有什么想法吗？或者，如果能提供成功compute.v1.instanceTemplate部署的示例，我们将不胜感激。

答案1

事实证明，其中一个高级部署示例确实有一个compute.v1.instanceTemplate 使用示例zone。资源应该指定一个，而不是一个project，这确实更有意义，尽管除了这个例子之外，似乎没有任何地方记录这一点。然而，不太合理的是，实际的instanceTemplate参数放在里面其他properties 对象。不确定这是从哪里来的，但这是我最终工作的 jinja 模板（请注意，一些字段正在使用其默认值，实际上可以省略）：

resources:
  - name: {{ env["name"] }}
    type: compute.v1.instanceTemplate
    properties:
      project: {{ env["project"] }}
      properties:
        machineType: {{ properties["machineType"] }}
        canIpForward: true
        scheduling:
          automaticRestart: true
          onHostMaintenance: MIGRATE
          preemptible: false
        tags:
          items:
            - redacted
        disks:
          - deviceName: boot
            boot: true
            autoDelete: true
            mode: READ_WRITE
            type: PERSISTENT
            initializeParams:
              diskSizeGb: 10
              diskType: pd-standard
              sourceImage: https://www.googleapis.com/compute/v1/projects/{{ env["project"] }}/global/images/redacted
        networkInterfaces:
          - network: $(ref.{{ properties["network"] }}.selfLink)
        serviceAccounts:
          - email: default
            scopes:
              - https://www.googleapis.com/auth/devstorage.read_only
