python-3.x - 在 GCP 中使用 python 代码创建 VM 实例时出现问题

问题描述

我正在尝试编写一个代码，该代码将从 excel 文件中读取值并在 Google Cloud 中创建虚拟机。我在两个位置遇到问题，如果我使用 'items': [tag] 创建标签，或者在创建服务帐户范围时它开始给我错误。

import os, json
import googleapiclient.discovery
from google.oauth2 import service_account
import csv

credentials = service_account.Credentials.from_service_account_file('G:/python/json/mykids-280210.json')
compute = googleapiclient.discovery.build('compute', 'v1', credentials=credentials)

def create_instance(compute, vm_name, image_project, image_family, machinetype, startupscript, zone, network,
                          subnet, project, scope, tag):
    # Get the latest Debian Jessie image.
    image_response = compute.images().getFromFamily(
        project=image_project, family=image_family).execute()
    source_disk_image = image_response['selfLink']

    # Configure the machine
    machine_type = "zones/" + zone + "/machineTypes/" + machinetype
    startup_script = startupscript

    config = {
        'name': vm_name,
        'machineType': machine_type,

        'description': 'This VM was created with python code',

        'tags': {
            'items': ['external', 'home', 'local']              #'items': [tag] <~~~~~~~~~~~
        },

        'deletionProtection': False,

        'labels': {'env': 'dev', 'server': 'mytower', 'purpose': 'personal'},

        # Specify the boot disk and the image to use as a source.
        'disks': [
            {
                'boot': True,
                'autoDelete': True,
                'initializeParams': {
                    'sourceImage': source_disk_image,
                }
            }
        ],

        # Specify a network interface with NAT to access the public
        # internet.
        'networkInterfaces': [{
            'network': 'global/networks/' + network,
            'subnetwork': 'regions/us-central1/subnetworks/' + subnet,
            'accessConfigs': [
                {'type': 'ONE_TO_ONE_NAT', 'name': 'External NAT'}
            ]
        }],

        # Allow the instance to access cloud storage and logging.
        'serviceAccounts': [{
            'email': 'default',
            'scopes': [
                #'https://www.googleapis.com/auth/devstorage.read_write', 'https://www.googleapis.com/auth/logging.write'
                #scope                          # scope      <~~~~~~~~~~~~~~~~~~~~
            ]
        }],
        'scheduling': {
            "preemptible": True
        },

        # Metadata is readable from the instance and allows you to
        # pass configuration from deployment scripts to instances.
         'metadata': {
            'items': [{
        # Startup script is automatically executed by the
        # instance upon startup.
                'key': 'startup-script',
                'value': startup_script
            }]
         }
    }

    return compute.instances().insert(
        project=project,
        zone=zone,
        body=config).execute()
# [END create_instance]

with open('vms.csv', newline='') as csvfile:
    data = csv.DictReader(csvfile)
    for row in data:
        vm_name = row['vm_name']
        image_project = row['image_project']
        image_family = row['image_family']
        machinetype = row['machinetype']
        startupscript = row['startupscript']
        zone = row['zone']
        network = row['network']
        subnet = row['subnet']
        project = row['project']
        scope = row['scopes']
        tag = row['tags']

        print(create_instance(compute, vm_name, image_project, image_family, machinetype, startupscript, zone, network,
                          subnet, project, scope, tag))
    csvfile.close()

使用范围变量时出错

G:\python\pythonProject\venv\Scripts\python.exe G:/python/pythonProject/read-excel-gcp/vm/create_vm.py
Traceback (most recent call last):
  File "G:\python\pythonProject\read-excel-gcp\vm\create_vm.py", line 100, in <module>

    return compute.instances().insert(

Process finished with exit code 1

当我使用标签变量时，我得到了类似的错误。

我在上面的代码中传递了 # 值。

以下是我的 csv 文件详细信息

vm_name,image_project,image_family,machinetype,startupscript,zone,network,subnet,project,scopes,tags
python-vm1,debian-cloud,debian-9,e2-micro,G:/python/json/startup-script.sh,us-central1-a,myvpc,subnet-a,mykids-280210,"https://www.googleapis.com/auth/devstorage.read_write',  'https://www.googleapis.com/auth/logging.write'","external', 'home', 'local'"
python-vm2,debian-cloud,debian-9,e2-micro,G:/python/json/startup-script.sh,us-central1-a,myvpc,subnet-a,mykids-280210,"https://www.googleapis.com/auth/devstorage.read_write',  'https://www.googleapis.com/auth/logging.write'","external', 'home', 'local'"

我不确定当直接传递值时它是否有效，但是当通过变量传递值时，它会失败。

我已经用<~~~~~~~~~~~~标记了问题区域

请建议是否有人理解这个问题。
