使用API快捷创建ECS

有时候会有不断重复的创建某个特定配置的ECS的需求，在第一次控制台页面上创建时，在快结束时，可以将调用代码保存下来，这样以后就可以直接调用快速创建。
比如，保存的创建某个8C32G、镜像CentOS7.9、设置好VPC,ROOT密码的ECS，它的python代码如下，这个是调用 huaweicloudsdkcore 和 huaweicloudsdkecs 提供的SDK/API来实现ECS创建。

# coding: utf-8

from huaweicloudsdkcore.auth.credentials import BasicCredentials
from huaweicloudsdkecs.v2.region.ecs_region import EcsRegion
from huaweicloudsdkcore.exceptions import exceptions
from huaweicloudsdkecs.v2 import *

if __name__ == "__main__":
    ak = "??RYLI??"
    sk = "??s7gcg3??"

    credentials = BasicCredentials(ak, sk) \

    client = EcsClient.new_builder() \
        .with_credentials(credentials) \
        .with_region(EcsRegion.value_of("cn-south-1")) \
        .build()

    try:
        request = CreateServersRequest()
        listPrePaidServerTagServerTagsServer = []
        listPrePaidServerMetadataServer = {
            "op_svc_userid": "???7ad4a00f2d41f5bc00a59???",
            "admin_pass": "",
            "__support_agent_list": "hss,ces"
        }
        extendparamPrePaidServerExtendParam = PrePaidServerExtendParam(
            charging_mode="0",
            region_id="cn-south-1"
        )
        listPrePaidServerSecurityGroupSecurityGroupsServer = [
            PrePaidServerSecurityGroup(
                id="???-4396-4e74-a148-???"
            )
        ]
        listPrePaidServerDataVolumeDataVolumesServer = []
        extendparamPrePaidServerRootVolumeExtendParam = PrePaidServerRootVolumeExtendParam(
            resource_spec_code="GPSSD",
            resource_type="3"
        )
        rootVolumePrePaidServerRootVolume = PrePaidServerRootVolume(
            volumetype="GPSSD",
            size=40,
            extendparam=extendparamPrePaidServerRootVolumeExtendParam,
            hwpassthrough=False
        )
        listPrePaidServerNicNicsServer = [
            PrePaidServerNic(
                subnet_id="???-a0ca-4df7-b865-5ca84ad2a7ee",
                ip_address=""
            )
        ]
        serverPrePaidServer = PrePaidServer(
            image_ref="???-ab5e-4b0c-bcc0-52949077090c",
            flavor_ref="t6.2xlarge.4",
            name="tas",
            user_data="???KZWNobyAncm9vdDokNiREcEJabFpMTSRnMGY2OU9qSm9aYWE5blBXLnRMejNQMlRGaTZvcXlmclNSOFk0amJsV3JjQnNJeDM3aDlWZFhSczAwTDc4VGNZcnFpZmdhSWNIaDdSNG94M3FUQi5XMScgfCBjaHBhc3N3ZCAtZTs=",
            vpcid="???-825b-4ce5-874f-f302e08257bc",
            nics=listPrePaidServerNicNicsServer,
            count=1,
            is_auto_rename=False,
            root_volume=rootVolumePrePaidServerRootVolume,
            data_volumes=listPrePaidServerDataVolumeDataVolumesServer,
            security_groups=listPrePaidServerSecurityGroupSecurityGroupsServer,
            availability_zone="cn-south-1c",
            extendparam=extendparamPrePaidServerExtendParam,
            metadata=listPrePaidServerMetadataServer,
            server_tags=listPrePaidServerTagServerTagsServer,
            description=""
        )
        request.body = CreateServersRequestBody(
            server=serverPrePaidServer
        )
        response = client.create_servers(request)
        print(response)
    except exceptions.ClientRequestException as e:
        print(e.status_code)
        print(e.request_id)
        print(e.error_code)
        print(e.error_msg)

然后在运行这个python3脚本前，先安装一下SDK：
pip3 install huaweicloudsdkcore huaweicloudsdkecs
然后运行就可以了，很快可以在页面上看到一台ECS在创建中，一会就创建好了。
