亚马逊网络服务boto3 -如何运行spot实例？

import boto3

ec2_client = boto3.client('ec2')

spot_request_params = {
    'InstanceCount': 1,  # 实例数量
    'LaunchSpecification': {
        'ImageId': 'ami-12345678',  # 镜像ID
        'InstanceType': 't2.micro',  # 实例类型
        'KeyName': 'my-key-pair',  # 密钥对名称
        'SecurityGroupIds': ['sg-12345678'],  # 安全组ID列表
        'SubnetId': 'subnet-12345678'  # 子网ID
    },
    'SpotPrice': '0.01',  # Spot实例价格
    'Type': 'one-time'  # Spot实例请求类型
}

response = ec2_client.request_spot_instances(**spot_request_params)
spot_request_id = response['SpotInstanceRequests'][0]['SpotInstanceRequestId']

waiter = ec2_client.get_waiter('spot_instance_request_fulfilled')
waiter.wait(SpotInstanceRequestIds=[spot_request_id])

spot_instance_id = ec2_client.describe_spot_instance_requests(
    SpotInstanceRequestIds=[spot_request_id]
)['SpotInstanceRequests'][0]['InstanceId']

ec2_client.create_tags(
    Resources=[spot_instance_id],
    Tags=[
        {'Key': 'Name', 'Value': 'My Spot Instance'}
    ]
)
