用于在将实例数据导出到CSV时列出超过30天的EBS快照的Boto3脚本

import boto3
import csv
from datetime import datetime, timedelta

# 配置AWS凭证
session = boto3.Session(
    aws_access_key_id='your_access_key_id',
    aws_secret_access_key='your_secret_access_key',
    region_name='your_region_name'
)

# 连接到EC2服务
ec2_client = session.client('ec2')

# 获取所有EBS快照信息
snapshots = ec2_client.describe_snapshots(OwnerIds=['self'])['Snapshots']

# 筛选超过30天的快照
today = datetime.now().replace(hour=0, minute=0, second=0, microsecond=0)
old_snapshots = []

for snapshot in snapshots:
    if (today - snapshot['StartTime']).days > 30:
        old_snapshots.append(snapshot)

# 设置CSV文件路径和文件名
csv_file = 'ebs_snapshots.csv'

# 将快照信息写入CSV文件
with open(csv_file, 'w', newline='') as file:
    writer = csv.writer(file)
    writer.writerow(["Snapshot ID", "Volume ID", "Start Time"])

    for snapshot in old_snapshots:
        writer.writerow([snapshot['SnapshotId'], snapshot['VolumeId'], snapshot['StartTime']])
