写一个awslightsail更换ip脚本

以下是一个使用Python编写的AWS Lightsail更换IP地址的脚本：

import boto3
import time

def get_instance_id():
    client = boto3.client('lightsail', region_name='us-west-2')
    response = client.get_instances()
    instances = response['instances']
    
    for instance in instances:
        if instance['state']['name'] == 'running':
            return instance['name']
    
    return None

def create_static_ip():
    client = boto3.client('lightsail', region_name='us-west-2')
    response = client.allocate_static_ip()
    return response['staticIp']['name']

def attach_static_ip(instance_id, static_ip):
    client = boto3.client('lightsail', region_name='us-west-2')
    response = client.attach_static_ip(
        staticIpName=static_ip,
        instanceName=instance_id
    )
    return response

def detach_static_ip(static_ip):
    client = boto3.client('lightsail', region_name='us-west-2')
    response = client.detach_static_ip(
        staticIpName=static_ip
    )
    return response

def release_static_ip(static_ip):
    client = boto3.client('lightsail', region_name='us-west-2')
    response = client.release_static_ip(
        staticIpName=static_ip
    )
    return response

def wait_for_running(instance_id):
    client = boto3.client('lightsail', region_name='us-west-2')
    while True:
        response = client.get_instance_state(
            instanceName=instance_id
        )
        state = response['state']['name']
        if state == 'running':
            break
        time.sleep(5)

def main():
    instance_id = get_instance_id()
    if not instance_id:
        print('No running instance found')
        return
    
    current_ip = None
    static_ip = None
    
    try:
        # 获取当前实例的静态IP
        client = boto3.client('lightsail', region_name='us-west-2')
        response = client.get_instance(instanceName=instance_id)
        current_ip = response['instance']['publicIpAddress']
        
        # 创建一个新的静态IP
        static_ip = create_static_ip()
        
        # 将新的静态IP分配给实例
        attach_static_ip(instance_id, static_ip)
        
        # 等待实例重新启动
        wait_for_running(instance_id)
        
        # 获取新的静态IP地址
        response = client.get_instance(instanceName=instance_id)
        new_ip = response['instance']['publicIpAddress']
        
        print(f'Old IP: {current_ip}')
        print(f'New IP: {new_ip}')
    except Exception as e:
        print(f'Error: {str(e)}')
    finally:
        if current_ip and static_ip:
            # 将新的静态IP从实例中分离
            detach_static_ip(static_ip)
            
            # 释放静态IP
            release_static_ip(static_ip)

if __name__ == '__main__':
    main()

请确保安装了AWS SDK for Python（Boto3），并将脚本中的region_name参数设置为您实际使用的区域。此脚本将执行以下操作：

1. 获取当前正在运行的实例的ID。
2. 获取当前实例的公共IP地址。
3. 创建一个新的静态IP地址。
4. 将新的静态IP地址分配给实例。
5. 等待实例重新启动。
6. 获取新的静态IP地址。
7. 打印旧IP地址和新IP地址。
8. 将新的静态IP地址从实例中分离。
9. 释放静态IP地址。

请注意，此脚本假设您在us-west-2区域使用AWS Lightsail。如果您使用其他区域，请相应地修改代码中的region_name参数
