我试图复制在谷歌网站https://cloud.google.com/compute/docs/tutorials/python-guide上找到的以下指南
我不知道桶和计算是什么意思。我需要向脚本中传递什么类型的参数?如果我想开始我的私有镜像,我应该在getFromFamily( project='debian-cloud',family='debian-8').execute()中放什么?我是不是像下面这样传入变量?
create_instance(compute,projectname, us-east1-a, instance-1, bucket)我简化了脚本,如下所示。我去掉了我不需要的参数。
def create_instance(compute, project, zone, name, bucket):
image_response = compute.images().getFromFamily(
project='debian-cloud', family='debian-8').execute()
source_disk_image = image_response['selfLink']
# Configure the machine
machine_type = "us-east1-b/%s/machineTypes/f1-micro" % zone
startup_script = open(
os.path.join(
os.path.dirname(__file__), 'startup-script.sh'), 'r').read()
config = {
'name': instance-1,
'machineType': f1-micro,
# Specify the boot disk and the image to use as a source.
'disks': [
{
'boot': True,
'autoDelete': True,
'initializeParams': {
'sourceImage': /global/imagename,
}
}
],
# Specify a network interface with NAT to access the public
# internet.
'networkInterfaces': [{
'network': 'global/networks/default',
'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',
]
}],
# 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
}, {
'key': 'bucket',
'value': bucket
}]
}
}
return compute.instances().insert(
project=project,
zone=zone,
body=config).execute()发布于 2017-03-01 19:37:05
这在这里已经有一段时间了,但这里有一些信息。
仅当您希望实例具有共享存储位置(文档here)时,才需要bucket。如果不需要存储桶,则应该删除元数据bucket键值(尽管我很惊讶地看到使用假存储桶名称创建实例不会失败)。
compute是经过身份验证的客户端对象,用于与“计算引擎”服务进行交互。要获取客户端,您需要遵循这些instructions来获取密钥、密钥和刷新令牌。下面是一个代码示例:
from googleapiclient import discovery
from oauth2client.client import GoogleCredentials
from oauth2client import GOOGLE_TOKEN_URI
credentials = GoogleCredentials(access_token=None, client_id='your-client-id',
client_secret='your-client-secret',
refresh_token='your-refresh-token',
token_expiry=None, token_uri=GOOGLE_TOKEN_URI,
user_agent='Python client library')
compute = discovery.build('compute', 'v1', credentials=credentials)至于私有镜像,如果您想使用相同的代码,那么您需要在您的GCE console中找到并识别它们,并提供project和family标识符。您也可以使用该接口按名称获取镜像:
image = compute.images().get(project='your-project-id', image='your-image-name').execute(),其中需要提供与实例config中的sourceImage相同的image['selfLink']

这个例子已经过时了:注意oauth2client现在已经过时了,Google Auth是当前的客户端库。这是一个最新的解决方案。关键的一步是生成正确的更新json。这可以通过在授权的服务帐户下使用等效的REST命令转换您的预期实例来实现。

import google.auth
import googleapiclient.discovery
PROJECT_ID = "<your project ID>"
ZONE = "<your zone>"
credentials, _ = google.auth.default()
compute = googleapiclient.discovery.build('compute', 'v1',
credentials=credentials)
config = "{generate your instance's json from equivalent REST}"
compute.instances().insert(project=PROJECT_ID, zone=ZONE,
body=config).execute()https://stackoverflow.com/questions/40764114
