Question

我有一个部署，其中包括一个托管实例组和两个实例模板（A和B）。最初使用实例组引用实例模板A创建了部署。

我尝试使用Deployment Manager更新实例模板B中的sourceImage（ gcloud beta Deployment-manager部署更新了my-deployment --template ... ），但是出现了以下错误：

ERROR: (gcloud.beta.deployment-manager.deployments.update) Error in 
Operation [operation-1538798895713-57787898f4ae9-8b478716-0bb72a09]: 
errors:
- code: NO_METHOD_TO_UPDATE_FIELD
  message: No method found to update field 'properties' on 
  resource 'fwp-app-preprod-instance-template-a' of type 
  'compute.v1.instanceTemplate'. The resource may need to be
  recreated with the new field.

我应该明确指出，我对原始部署所做的唯一更改是实例模板的sourceImage。

是否可以通过Deployment Manager执行实例模板的更新，以便它引用更新的sourceImage？

该错误清楚地表明可能需要重新创建资源（实例模板），我很高兴Deployment Manager能够做到这一点。但是我不知道如何指示/强制部署管理器执行该操作。

我毫不怀疑它可以在Deployment Manager之外完成，但我想避免配置漂移。

我的app.jinja.schema：

imports:
- path: instance-group.jinja
- path: instance-template.jinja

我的app.jinja：

resources:
- name: instance-template-a
  type: instance-template.jinja
  properties:
    name: {{ env["deployment"] }}-instance-template-a
    machineType: g1-small
    sourceImage: "projects/my-project/global/images/my-image"
    diskSizeGb: '30'

- name: instance-template-b
  type: instance-template.jinja
  properties:
    name: {{ env["deployment"] }}-instance-template-b
    machineType: g1-small
    sourceImage: "projects/my-project/global/images/my-image"
    diskSizeGb: '30'

- name: fwp-instance-group
  type: instance-group.jinja

我的instance-group.jinja：

resources:

  type: compute.v1.regionInstanceGroupManager
  properties:
    baseInstanceName: ig-instance-{{ env["deployment"] }}
    instanceTemplate: '$(ref.{{ env["deployment"] }}-instance-template-a.selfLink)'
    targetSize: 1
    region: australia-southeast1

      minNumReplicas: 2
    target: $(ref.instance-group-{{ env["deployment"] }}.selfLink)

还有我的instance-template.jinja

resources:

要重述评论：

DM配置包括托管实例组的实例模板。更改源图像正在尝试更改模板中使用的图像。

很遗憾，instance templates are immutable once created

“因此，无法在创建现有实例模板后对其进行更新或更改。”

这说明了返回的错误消息。更改要用于托管实例组的映像的正确方法是创建一个新模板，并在该组上执行rolling update，并使用新实例模板。
