用于创建 VM 实例的 GCP 云功能无法识别我的自定义映像

Question

我正在尝试在 Python 中创建一个云函数，该函数使用我之前创建的自定义映像构建 VM 实例。

源图像出现在图像部分：

但是，当我运行 Cloud Function 时，它找不到我的镜像来构建实例并返回以下错误：

Details: "Invalid value for field 'resource.disks[0].initializeParams.sourceImage': 'projects/<<project id>>/global/images/pandora-pagespeed-image'. The referenced image resource cannot be found.">

此外，如果我在控制台中手动创建 VM 实例，图像也不会出现在此处：

更奇怪的是，正在出现的图像（pandora-image）是昨天删除的旧图像。

这里可能发生了什么？

我的云函数代码是：

import os
from googleapiclient import discovery
from google.oauth2 import service_account

scopes = ['https://www.googleapis.com/auth/cloud-platform']
sa_file = <<credentials file>>
zone = 'europe-west2-c'
project_id = <<project id>> # Project ID, not Project Name

credentials = service_account.Credentials.from_service_account_file(sa_file, scopes=scopes)

# Create the Cloud Compute Engine service object
service = discovery.build('compute', 'v1', credentials=credentials)

def create_instance(compute, project, zone, name):
    # Get the latest Debian Jessie image.
    image_response = (
        compute.images()
        .getFromFamily(project="debian-cloud", family="debian-9")
        .execute()
    )
    source_disk_image = image_response["selfLink"]

    # Configure the machine
    machine_type = "zones/%s/machineTypes/n1-standard-1" % zone
    config = {
        "name": name,
        "machineType": machine_type,
        # Specify the boot disk and the image to use as a source.

            }
        ],
        "tags": {"items": ["http-server", "https-server"]},
    }

    return compute.instances().insert(project=project, zone=zone, body=config).execute()

def run(data, context):
    create_instance(service, project_id, zone, "vm-instance")

我现在意识到我做错了什么。

我在“machine images”部分而不是“图像”部分创建了我的图像。因此，为什么找不到我的图像...DOH！
