使用boto3查看ec2实例附加的弹性IP

import boto3

ec2_client = boto3.client('ec2')

response = ec2_client.describe_instances()

for reservation in response['Reservations']:
    for instance in reservation['Instances']:
        instance_id = instance['InstanceId']
        elastic_ips = instance.get('NetworkInterfaces', [{}])[0].get('Association', {}).get('PublicIp')
        if elastic_ips:
            print(f"Instance ID: {instance_id}")
            print(f"Elastic IP: {elastic_ips}")
