使用botocore.client在Python中批量删除AWSEC2实例

发布时间：2023-12-23 08:24:38

要使用botocore.client在Python中批量删除AWSEC2实例，首先需要安装boto3库。然后可以按照以下步骤进行操作：

1. 引入必要的库和模块

import boto3
from botocore.exceptions import NoCredentialsError

2. 设置AWS认证凭证

ACCESS_KEY = 'your_access_key'
SECRET_KEY = 'your_secret_key'

请将"your_access_key"和"your_secret_key"替换为您的实际访问密钥。

3. 创建EC2客户端

def create_ec2_client(access_key, secret_key):
    try:
        ec2_client = boto3.client('ec2', aws_access_key_id=access_key, aws_secret_access_key=secret_key)
        return ec2_client
    except NoCredentialsError:
        print("AWS认证凭证不正确或缺失")
        return None

4. 批量删除EC2实例

def delete_ec2_instances(ec2_client, instance_ids):
    response = ec2_client.terminate_instances(InstanceIds=instance_ids)
    return response

这里的instance_ids是一个实例ID列表，表示要删除的EC2实例的ID。

5. 完整示例

import boto3
from botocore.exceptions import NoCredentialsError

ACCESS_KEY = 'your_access_key'
SECRET_KEY = 'your_secret_key'

def create_ec2_client(access_key, secret_key):
    try:
        ec2_client = boto3.client('ec2', aws_access_key_id=access_key, aws_secret_access_key=secret_key)
        return ec2_client
    except NoCredentialsError:
        print("AWS认证凭证不正确或缺失")
        return None

def delete_ec2_instances(ec2_client, instance_ids):
    response = ec2_client.terminate_instances(InstanceIds=instance_ids)
    return response

def main():
    ec2_client = create_ec2_client(ACCESS_KEY, SECRET_KEY)
    if ec2_client is not None:
        instance_ids = ['instance_id1', 'instance_id2', 'instance_id3']  #替换为您要删除的实例ID列表
        response = delete_ec2_instances(ec2_client, instance_ids)
        print(response)

if __name__ == '__main__':
    main()

这个示例代码将会删除instance_ids列表中指定的EC2实例。请确保将"your_access_key"、"your_secret_key"和实例ID列表都替换为适当的值。
