我的部署包含一个托管实例组和两个实例模板(A 和 B)。部署最初是使用引用实例模板 A 的实例组创建的。
我尝试使用部署管理器( gcloud beta deployment-manager deployments update my-deployment --template ... )更新实例模板 B 中的 sourceImage ,但出现以下错误:
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。
是否可以通过部署管理器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),我很高兴部署管理器这样做。但我不知道如何指示/强制部署经理采取该行动。
我不怀疑它可以在部署管理器之外完成,但我想避免配置漂移。
