云主机怎么实现

import tencentcloud.common.credentials
import tencentcloud.common.profile.client_profile
import tencentcloud.common.profile.http_profile
import tencentcloud.cvm.v20170312.cvm_client

# 配置凭证信息
cred = tencentcloud.common.credentials.Credential("SecretId", "SecretKey")
httpProfile = tencentcloud.common.profile.http_profile.HttpProfile()
httpProfile.endpoint = "cvm.tencentcloudapi.com"

clientProfile = tencentcloud.common.profile.client_profile.ClientProfile()
clientProfile.httpProfile = httpProfile
client = tencentcloud.cvm.v20170312.cvm_client.CvmClient(cred, "Region", clientProfile)

# 创建云主机请求
request = tencentcloud.cvm.v20170312.models.RunInstancesRequest()
request.ImageId = "img-xxxxxx"
request.InstanceType = "S2.SMALL1"
request.InstanceChargeType = "POSTPAID_BY_HOUR"
request.InstanceName = "TestInstance"
request.Placement = {"Zone": "ap-guangzhou-2"}
request.SystemDisk = {"DiskType": "CLOUD_PREMIUM", "DiskSize": 50}
request.VirtualPrivateCloud = {"VpcId": "vpc-xxxxxx", "SubnetId": "subnet-xxxxxx"}

# 发送请求
response = client.RunInstances(request)
print(response.to_json_string(indent=2))
