如何获取使用 boto3 创建的 spot 实例的 ip 地址

Question

我可以使用以下代码使用 boto3 创建 spot 实例

import boto3
import datetime, random, string
client = boto3.client('ec2')
response = client.request_spot_instances(
    DryRun=False,
    ClientToken=''.join(random.choices(string.ascii_uppercase + string.digits, k=10)),
    InstanceCount=1,
    Type='one-time',
    LaunchSpecification={
        'ImageId': 'ami-053ebee0bc662f9b3',
        'SecurityGroups': ['default'],
        'InstanceType': 't3.medium',
        'Placement': {
            'AvailabilityZone': 'us-east-1a',
        },
        'BlockDeviceMappings': [
            {
            },
        ],
        'EbsOptimized': True,
        'Monitoring': {
            'Enabled': True
        },
        'SecurityGroupIds': [
            'sg-03432e1f',
        ]
    }
)
print(response)

我得到的回复如下。我怎样才能得到所有创建的机器的IP地址。我知道请求是异步的，但是如果我想轮询创建实例的详细信息，有什么办法？

与常规实例相同。您必须获得 NetworkInterfaceId 个可以使用 describe_instances 获得的 spot 实例。调用的结果为您提供 InstanceLifecycle 等于 spot 的现货实例。

一旦您拥有 NetworkInterfaceId 个 spot 实例，您就可以使用 describe_network_interfaces 获得与接口关联的 PublicIp。
